Cryotherapy, Topical Treatment or Lesion Removal for Molluscum: How the Options Compare

The bumps started as three pearly dots on a seven-year-old’s ribs, easy to mistake for goosebumps. By swim season there were twenty, some with a red halo, one weeping where a towel had caught it. The parent in the exam room has already read the message boards and arrives with the question that brings most families to a dermatology visit for this condition: freeze them, put something on them, or scrape them off?

Adults ask the same thing about a cluster on the inner thigh or lower abdomen, usually with more embarrassment and the same urgency. The honest answer to cryotherapy vs topical molluscum treatment is less dramatic than the internet suggests. Each approach works on a different principle, each has a different trade-off between speed, discomfort and scarring, and the strongest evidence points to something people rarely want to hear: patience is a legitimate treatment plan.

What follows is a plain account of what each option involves, who is usually offered which, and what the research does and does not support.

What molluscum contagiosum is, and why treatment is really a timing question

Molluscum contagiosum is a skin infection caused by a poxvirus, a family of viruses that live in the outer layer of skin and trigger small, dome-shaped bumps. The bumps are typically 2 to 5 millimeters across, firm, flesh-colored or pink, and many have a tiny dimple in the center, according to MedlinePlus. Inside each one sits a core of virus-laden material, which is why scratching a bump and then touching skin elsewhere can seed new ones.

The virus spreads by skin-to-skin contact, by shared towels or sports equipment, and by sexual contact in adults. Children pick it up in daycare, at the pool and through wrestling on the living room floor. Adults with a weakened immune system, and people with eczema, tend to develop more bumps and keep them longer.

Here is the fact that reframes every treatment conversation. The immune system usually clears molluscum by itself. The CDC notes that bumps typically resolve within 6 to 12 months without treatment, though in some people the process can stretch to 4 years. The NHS puts the usual window at up to 18 months. New bumps may keep appearing while older ones fade, so the total course often looks longer than the life of any single spot.

That is why a clinician weighing cryotherapy against a topical agent or curettage is really weighing three questions. How much are the bumps bothering this person, physically or socially? How fast are they spreading, and to whom? And would a treatment with its own discomfort and scarring risk actually beat the natural course by enough to justify it? The rest of this article is about how each option answers those questions.

Cryotherapy vs topical molluscum treatment: what each approach actually does

The three options in the title work by three different mechanisms, and understanding them makes the trade-offs obvious.

Cryotherapy is the application of extreme cold, almost always liquid nitrogen, to freeze the bump and the shallow skin beneath it. Freezing kills the virus-filled cells directly and provokes a small blister; as the blister heals, the dead tissue and the viral core lift away with it. The effect is immediate and local. Whatever the clinician freezes is treated that day, and whatever they do not freeze is not.

Topical treatments are creams, gels or solutions applied to the skin. Most work by irritation rather than by killing the virus outright. A blistering agent such as cantharidin lifts the top of the bump off within a day or two. Peeling agents such as salicylic acid or potassium hydroxide dissolve the outer layers over repeated applications. Retinoid creams speed skin turnover. Some agents, including a newer nitric oxide-releasing gel, aim to disrupt the virus more directly. All of them rely on the local inflammation they cause to wake the immune system up to the infection.

Lesion removal, most often curettage, is mechanical. A curette is a small spoon-shaped instrument that scrapes the bump and its core out of the skin. Some clinicians instead squeeze the core out with forceps or use a fine needle. Laser treatment, which vaporizes the bump with focused light, is a less common variant in the same category.

So the real cryotherapy vs topical molluscum comparison is about speed against control. In-office procedures are fast but hurt in the moment and depend on catching every bump. Home topicals are gentler per application but slower, and their pace depends on skin sensitivity and how consistently they are used.

What happens during a cryotherapy appointment for molluscum

Cryotherapy for molluscum is a brief clinic procedure, usually done in the same visit as the diagnosis if everyone agrees to proceed. No anesthetic injection is typically needed, though a numbing cream is sometimes applied beforehand for younger children or for bumps in tender areas.

The clinician uses either a spray canister or a cotton-tipped applicator dipped in liquid nitrogen. Each bump is frozen for a few seconds until a small white halo of frost forms around it, then allowed to thaw. The freeze-thaw cycle is sometimes repeated once. Most people describe the sensation as a sharp sting followed by a burning ache that settles within minutes. A child with twenty bumps will feel this twenty times, which is the main reason cryotherapy is used cautiously in young children.

Over the next hours, the treated spots redden and may swell. A blister, sometimes filled with clear or blood-tinged fluid, often forms within a day. The blister dries into a scab over several days and the scab falls away, ideally taking the bump with it. Because cryotherapy only treats what is visible on the day, bumps still incubating under the skin can appear afterward, so repeat sessions spaced a few weeks apart are common practice; the CDC lists cryotherapy among treatments that may require more than one visit.

The main risks are temporary pain, blistering, and a pale or dark mark where the skin was frozen. In darker skin tones, loss of pigment at the treated site can persist for months and occasionally longer. Small, pitted scars are possible if the freeze is deep or the blister becomes infected. Cryotherapy is generally avoided on the eyelids and used sparingly on the face.

Which topical treatments are used for molluscum, and how they work

Topical options fall into two groups: those applied by a clinician in the office and those used at home under instruction.

Cantharidin is the best-known office-applied agent. It is a blistering compound derived from a beetle, painted onto each bump with a fine applicator and washed off after a set time given by the clinician. Because it is painless on application and blisters only later, it has long been used in children. The blister that forms over the next day or two lifts the bump away. It is not used on the face or genital area because blistering there is unpredictable. It must be applied by a trained clinician; this is not a home treatment.

Home-applied agents include podophyllotoxin, a plant-derived compound that stops infected cells dividing; potassium hydroxide solution, which dissolves the outer skin; salicylic acid, a peeling agent familiar from wart preparations; and retinoid creams such as tretinoin, which speed skin turnover. Imiquimod, a cream that stimulates immune activity in the skin, was once popular, but the evidence discussed later in this article does not support it for molluscum. A nitric oxide-releasing gel is a newer prescription option that works on the virus itself.

All home topicals share a rhythm. They are applied to individual bumps, not spread across the whole area, for a period of weeks. Redness, stinging and mild peeling are expected signs that the agent is working rather than reasons to stop, but a raw or weeping patch means the skin has had enough and the prescriber should be told. The prescribing clinician sets how often to apply, for how long, and when to pause. None of these agents should be used on a bump that has not been confirmed as molluscum, since a mistaken diagnosis could delay treatment of something else.

Molluscum curettage removal and other lesion removal: what the appointment involves

Curettage is the most direct way to get rid of a molluscum bump. After cleaning the skin, and usually after applying a numbing cream and waiting for it to take effect, the clinician uses the curette to scoop out the bump along with its central core in a single motion. Each bump takes seconds. A little pinpoint bleeding is normal and is controlled with pressure or a dab of a chemical that seals small vessels.

The appeal is obvious. The bump is gone when the patient leaves, and there is no waiting for a blister or weeks of cream. The core, the most infectious part, is removed rather than left to leak during a blistering phase. For a handful of bumps in an older child or adult, or for a stubborn bump in an awkward spot such as an armpit or the edge of a diaper area, curettage is often the first thing a dermatologist reaches for.

The disadvantages scale with numbers. Scraping fifty bumps off a squirming five-year-old is not realistic without sedation, which brings its own risks and is rarely justified for a self-limiting condition. Even with numbing cream, the sensation is unpleasant, and children who have one bad experience can refuse future visits. Each scraped site is a tiny open wound, so infection and a small scar are possible, and pigment changes can follow in darker skin.

Squeezing bumps with forceps to express the core is a quicker variant with similar trade-offs. Laser treatment is reserved for extensive cases, particularly in adults with immune suppression where standard approaches have not helped. The CDC lists both curettage and laser among physical removal options and notes that scarring is a recognized risk of the physical methods.

Who is usually offered treatment for molluscum, and who is usually asked to wait

Because molluscum clears on its own in most people, the default recommendation in healthy children is to leave it alone. The NHS advises that treatment is not usually needed, and the CDC describes watchful waiting as a reasonable option. Parents often find this frustrating, so it helps to understand who moves off the waiting list and why.

Treatment is more likely to be offered when bumps are on the face, neck or genital area, where they are visible or socially awkward and where spread is hard to prevent. It is considered when bumps are inflamed, itchy or repeatedly bleeding, when a child with eczema is scratching them into an ever-widening patch, or when new bumps are appearing faster than old ones fade. Adults with genital molluscum are usually offered treatment both for comfort and to reduce spread to partners. People with a weakened immune system, including those with untreated HIV, may develop large or numerous bumps that do not resolve, and for them treatment of the underlying condition matters as much as anything applied to the skin.

People commonly asked to wait include infants and toddlers with a few bumps on the trunk or limbs, anyone whose bumps are already showing signs of clearing, and those for whom the discomfort of treatment would outweigh the nuisance of the bumps. Pregnant people are usually steered away from certain topical agents, and the treating clinician will make that call.

A middle path exists. Many clinicians treat only the bumps that are bothersome or in high-risk spots and leave the rest, revisiting the plan in a few months. Whichever path is taken, it is a shared decision with the treating team, revised as the picture changes.

Cryotherapy vs topical molluscum vs curettage: how the options compare side by side

The table below summarizes the practical differences most families and adults ask about. It is descriptive, not a ranking, and the right column for one person can be the wrong one for another.

Feature	Cryotherapy	Topical treatments	Curettage or removal
Where it happens	Clinic	Clinic (cantharidin) or home (most others)	Clinic
Discomfort during	Sharp sting per bump	Little to none at application; later stinging or blistering	Pressure or pinch with numbing cream
Speed of effect	Days to a few weeks per session	Weeks of repeated use	Immediate
Repeat visits	Often needed as new bumps appear	Follow-up to review skin and progress	Sometimes, for new bumps
Main side effects	Blister, pigment change, small scar	Irritation, blistering, pigment change	Bleeding, infection, small scar
Suits many bumps?	Moderately	Yes, within tolerance	Poorly in young children
Use on face or genitals	Cautious	Agent-dependent; some avoided	Case by case
Usual candidates	Older children, adults, limited bumps	Children who cannot tolerate procedures; widespread bumps	Few bumps; older children and adults

Two patterns stand out. First, the procedures win on speed and lose on tolerability, and that trade-off tilts sharply with age. Second, no column is free of pigment change or scarring, which is the strongest argument for treating only the bumps that genuinely matter. In practice, clinicians mix and match: cantharidin on the trunk of a young child, cryotherapy on an adult’s thigh, curettage for the one bump at the eyelid margin that keeps getting rubbed. The systematic review evidence in the next section explains why this pragmatism is justified.

What the evidence actually shows about molluscum treatments

For a condition this common, the quality of treatment research is thin. The most rigorous summary is a Cochrane systematic review of interventions for cutaneous molluscum contagiosum, indexed on PubMed. A systematic review is a study that collects and grades all the trials on a question, and Cochrane reviews are widely regarded as the most cautious of these.

Its central finding is worth quoting in spirit: no single treatment was shown to be convincingly effective compared with placebo or with waiting. Most trials were small, many had design flaws, and follow-up was often too short to separate a treatment effect from natural clearance. The review did reach one moderate-quality conclusion of practical importance: imiquimod cream was no more effective than an inactive vehicle cream in children, and it caused more skin reactions. That is why a cream that once appeared on many prescriptions has faded from guideline lists.

The review found low-quality or insufficient evidence for cryotherapy, curettage, cantharidin, salicylic acid, potassium hydroxide and the other agents in this article. That does not mean they do nothing. Clinicians see bumps disappear after freezing or scraping every week. It means the trials have not been large or long enough to prove that treated people end up clear sooner than they would have anyway, and no head-to-head comparison has crowned a winner.

Since that review, two prescription topical products have been approved by the United States regulator specifically for molluscum, based on their own randomized trials. Their approval establishes that they can outperform an inactive comparator over the trial period; it does not tell us how they compare with cryotherapy or curettage, because those comparisons have not been run.

The honest reading is this. Treatment is a reasonable choice for the right person, waiting is a reasonable choice for many, and confident claims that one method is best are ahead of the data.

What the days and weeks after molluscum treatment usually look like

Whatever is chosen, the skin follows a predictable arc, and knowing it prevents unnecessary alarm.

After cryotherapy, expect redness within the hour and a blister within a day or two at some or all treated sites. The blister may be clear or blood-tinged. Leaving it intact is best; if it bursts, gently clean the area and cover it. A scab forms over several days and separates on its own in one to two weeks. Picking the scab off early raises the chance of a scar. Once the scab is gone, a pink or pale mark usually fades over weeks to months.

After cantharidin, the sequence is similar but delayed: a blister appears the day after application and resolves over about a week. The clinician will say when to wash the agent off and what to do if the blistering is more vigorous than expected.

Home topicals run on a slower clock. The first few days may show nothing. Over one to several weeks, treated bumps typically redden, flatten and peel. Redness around a bump is often the sign the immune system has found it, and untreated bumps sometimes fade at the same time. Persistent rawness is a signal to pause and check in with the prescriber.

After curettage, each site is a shallow wound that seals within a few days and heals fully in one to two weeks, leaving a pink dot that fades.

Across all options, new bumps can appear for weeks after treatment. These were incubating beneath the skin when the visit happened, not caused by the treatment. The CDC notes that even when treated, molluscum can recur or persist, and most clinicians schedule a review a few weeks out to decide whether a second round is warranted. Ordinary activities, including school, can continue, with covering of open sites as described below.

Molluscum treatment for children: what parents most often ask

Children are the main group affected, and their treatment path is shaped as much by temperament as by biology. Molluscum treatment for children is therefore less about which agent is strongest and more about what a particular child can tolerate without trauma.

The first question is almost always whether treatment is needed at all. For a healthy child with bumps on the trunk or limbs, most pediatric guidance, including the NHS, favors waiting. The CDC notes that treatment can be considered to reduce spread and for cosmetic or comfort reasons, and it is more often chosen when bumps are on the face, inflamed, or spreading across eczema-prone skin.

If treatment is chosen, cantharidin applied in the clinic is often favored for younger children because it does not hurt at the time of application. Cryotherapy and curettage are generally reserved for older children who can understand what is happening and consent to a brief sting, and for small numbers of bumps. Home topicals suit children with many scattered bumps, provided the parent can apply them consistently and stop if the skin becomes raw.

Preparation matters. Children do better when told truthfully what to expect, given a job such as holding a cold pack, and allowed to bring a comfort object. Numbing creams, when used, need time to work, so arriving early may be part of the plan. A clinician who offers to treat a few bumps first and see how the child copes is being sensible, not indecisive.

Schools and daycares in the United States do not generally exclude children with molluscum, and the CDC does not recommend keeping children home. Covering bumps with clothing or a watertight bandage during contact sports and swimming reduces spread to others. Decisions about which agent, how often and for how long rest with the treating clinician, never with a leaflet or a parenting forum.

Does molluscum go away on its own without any treatment?

Yes, in the large majority of people with a normally functioning immune system, molluscum resolves by itself. This is the single most important fact in any decision about treating it, and it is worth stating plainly because so much online content implies that untreated molluscum lingers indefinitely.

The mechanism is immune recognition. The virus lives in the outermost layer of skin, partly hidden from immune surveillance, which is why the bumps can sit quietly for months. Eventually the immune system finds them. When that happens, the bumps often turn red, swell and may look worse for a week or two before shrinking and disappearing. Clinicians sometimes call this the beginning-of-the-end sign, and it is frequently mistaken for infection or for the treatment going wrong.

The timelines from mainstream sources are consistent. The CDC states that molluscum usually resolves within 6 to 12 months without treatment and can take as long as 4 years in some people. The NHS advises that the bumps usually clear within 18 months. Individual bumps come and go within that span, so a parent may watch one crop fade while another arrives, which makes the overall course feel endless even when it is progressing normally.

Once the immune system has cleared the infection, the bumps do not scar unless they were scratched, picked or treated aggressively. That is a real advantage of waiting that gets lost in the impatience of the moment.

The exceptions are people with weakened immunity, in whom molluscum can be extensive and persistent, and people with eczema, whose disrupted skin barrier lets the virus spread more readily. For them, the natural course is less reliable and the treating team is more likely to intervene. For everyone else, waiting is not neglect. It is a plan with the best safety record of any option in this article.

How to stop molluscum spreading at home, at school and at the pool

Whether or not treatment is chosen, limiting spread is something every household can do, and it often matters more than the choice of agent. The virus moves in two ways: from one part of the body to another on fingers and towels, and from person to person by skin contact or shared items.

Within the person, scratching is the main culprit. Keeping fingernails short, controlling itch in children with eczema, and covering inflamed bumps with a small bandage all reduce self-seeding. Shaving over bumps spreads them in lines, so adults with molluscum on the legs, face or pubic area are advised to avoid shaving those areas until the bumps have gone. Avoid picking or squeezing bumps at home; the core is the most infectious part, and popping it releases it onto surrounding skin and under the nails.

Between people, the CDC recommends not sharing towels, clothing, razors or bath water, and washing hands after touching bumps. Bumps do not need to be covered under everyday clothing, but a watertight bandage is sensible during contact sports, gymnastics and swimming, where wet skin and shared equipment raise the risk. The virus does not spread through pool water itself; it spreads on shared towels, kickboards and skin-to-skin contact at the poolside.

Children do not need to stay home from school or daycare, and the CDC does not advise exclusion. Adults with genital molluscum should avoid sexual contact until the bumps have resolved, since condoms cover only part of the affected skin; a sexual health clinician can also check for other infections that are sometimes present alongside.

Household contacts who develop bumps should be seen for confirmation rather than self-treated, because other conditions can look similar. The virus does not survive long on dry surfaces, so ordinary laundering and cleaning are sufficient; no special disinfection is needed.

What people often get wrong about molluscum treatment

Several beliefs circulate widely enough to shape decisions, and most do not survive contact with the evidence.

Freezing is the strongest option, so it must be the best. Cryotherapy is fast and visible, but the Cochrane review found no convincing evidence that it clears molluscum faster than other methods or than waiting. Its main advantage is immediacy; its main cost is pain and pigment change.

Untreated molluscum lasts for years. The CDC’s typical range is 6 to 12 months, with 4 years as the outer bound in a minority. Most children are clear well within two years, treated or not.

Red, angry bumps mean infection or failed treatment. Redness around a bump is often the immune response that precedes clearance. True bacterial infection looks different: spreading warmth, pus, increasing pain and sometimes fever, covered in the red-flag section below.

Apple cider vinegar, tea tree oil or duct tape clear molluscum. None has trial evidence for this condition, and acids and oils applied to a child’s skin can cause chemical burns and contact dermatitis. If a home remedy appears to work, the most likely explanation is that the bumps were already resolving.

Topicals are the gentle option. Cantharidin blisters, potassium hydroxide can burn, and podophyllotoxin can inflame surrounding skin. Gentleness depends on the agent, the skin and the supervision, not on the category.

Popping bumps at home is the same as curettage. Curettage is done with sterile instruments, numbing, wound care and, crucially, someone who can tell molluscum from a mole, a wart or something that needs a biopsy. Squeezing at home spreads the core and invites scarring and infection.

Once treated, molluscum is gone. Bumps still incubating under the skin can surface weeks later. This is expected, not treatment failure, and it is why review visits are built into most plans.

Questions to ask your care team before choosing a molluscum treatment

A good consultation for molluscum ends with a plan the household understands and can follow. These questions help get there, and none of them is impertinent.

• Are you confident this is molluscum, and is there anything about these bumps that makes you want to rule out something else?
• Given the location and number of bumps, would you recommend waiting, treating some, or treating all, and what would change your mind?
• If we treat, which method do you suggest for this person and this part of the body, and why that one over the alternatives?
• What will the skin look like in the first week afterward, and what would be a sign that something is not healing as expected?
• How likely is a pale, dark or pitted mark at the treated site, and how does that risk compare with the mark left if we do nothing and the bumps clear on their own?
• If new bumps appear after treatment, do we come back, or is there a threshold we should wait for?
• For a home-applied agent, what does normal irritation look like, and when should we stop and call?
• Are there activities, sports or swimming to adjust, and for how long?
• Is there anything about eczema, other skin conditions or medicines already being taken that changes the plan?
• For an adult with genital bumps, should a sexual health check be part of this visit?
• When will you review progress, and who do we contact between visits?

Writing the answers down, or asking for them in a summary note, is worth doing. Molluscum plans stretch over months, and the details of which bumps to cover, which to treat and what counts as a reason to return are easy to blur. The final decision on method, timing and follow-up rests with the treating clinician, who can weigh the individual skin, the individual temperament and the individual household routine in a way no article can.

When to call your doctor about molluscum: red-flag signs

Molluscum itself is rarely dangerous, but its complications and its look-alikes sometimes are. Contact the treating clinician promptly, or seek same-day care, if any of the following develops.

• Signs of bacterial infection at a bump or a treated site: spreading redness or warmth, swelling, pus, increasing rather than easing pain, or a red streak tracking away from the area.
• Fever, chills or a generally unwell child or adult alongside skin changes.
• Bumps on or very near the eyelid margin, or any eye redness, discharge, grittiness or light sensitivity, since molluscum near the eye can inflame the eye surface and needs specialist assessment.
• A rapidly expanding rash or sudden appearance of many new bumps, particularly in someone with eczema, which can signal a widespread skin infection rather than ordinary molluscum spread.
• Large or unusually numerous bumps, or bumps that persist for years, in anyone with a weakened immune system or in an adult whose immune status has not been checked.
• A bump that bleeds without being scratched, grows steadily, changes color, or does not look like the others, because other skin conditions can mimic molluscum and may need a biopsy.
• After a topical treatment: raw, weeping, blistered skin beyond the treated bumps, severe burning, or blistering that is much larger than described.
• After cryotherapy or curettage: a wound that is not closing after two weeks, or one that reopens or enlarges.
• Any allergic-type reaction such as hives, facial swelling or difficulty breathing after a topical application, which needs emergency care.
• Genital bumps in an adult, which should prompt a sexual health assessment, or bumps in the genital area of a child, which the clinician will want to evaluate in person.

Between visits, uncertainty is itself a reason to call. Most of the trouble with molluscum comes not from the virus but from over-treatment, picking and misdiagnosis, all of which a quick conversation with the care team can head off.

Frequently asked questions

Is cryotherapy or topical treatment better for molluscum?

Neither has been shown to be clearly superior. A Cochrane systematic review found no single molluscum treatment convincingly more effective than others or than waiting. Cryotherapy is faster but stings and can leave pigment changes; topicals are gentler per application but take weeks and can irritate skin. Clinicians usually choose based on age, number and location of bumps, and how much discomfort the person can tolerate, rather than on evidence that one method wins.

Does molluscum go away on its own without treatment?

Yes, in most people with a normal immune system. The CDC reports that molluscum typically resolves within 6 to 12 months without treatment, occasionally taking up to 4 years, and the NHS gives a usual window of up to 18 months. Bumps often redden and swell shortly before they disappear, which is the immune system recognizing the virus. People with weakened immunity or eczema may have a longer, less predictable course.

Does molluscum treatment for children hurt?

It depends on the method. Cryotherapy causes a sharp sting per bump, and curettage involves a pinch or pressure even with numbing cream, so both are usually reserved for older children with few bumps. Cantharidin, applied in the clinic, does not hurt at application but blisters the next day. Home creams typically cause stinging or peeling over weeks. Many clinicians treat a few bumps first to see how a child copes before committing to more.

How long does it take for molluscum to clear after cryotherapy?

Treated bumps usually blister within a day or two, scab over several days, and shed the scab within one to two weeks. However, cryotherapy only treats bumps visible on the day, and new bumps incubating beneath the skin can appear over the following weeks. The CDC notes molluscum can persist or recur after treatment, so most plans include a review visit and, if needed, a repeat session.

What is molluscum curettage removal and does it leave scars?

Curettage is the scraping out of a molluscum bump and its core with a small spoon-shaped instrument, usually after numbing cream. The bump is gone immediately, leaving a shallow wound that heals in about one to two weeks. A small pink dot typically fades, but a tiny pitted scar or a pale or dark mark is possible, especially in darker skin or if the site becomes infected. Scarring risk is one reason it is used selectively.

How can I stop molluscum spreading to other family members?

Avoid sharing towels, clothing, razors and bath water, and wash hands after touching the bumps. Keep fingernails short and discourage scratching, since the virus spreads from bump to skin on fingers. Cover bumps with a watertight bandage during contact sports and swimming. Do not shave over affected areas. The CDC does not recommend keeping children out of school or daycare. Adults with genital bumps should avoid sexual contact until they have resolved.

Can I pop or squeeze molluscum bumps at home?

No. The central core is the most infectious part of the bump, and squeezing it at home spreads virus onto surrounding skin and under the nails, raises the risk of bacterial infection, and increases the chance of a scar. Clinic curettage differs because it uses sterile instruments, numbing, wound care and, crucially, confirmation that the bump is molluscum rather than a wart, mole or something needing a biopsy.

Do home remedies like apple cider vinegar or tea tree oil work on molluscum?

There is no trial evidence that vinegar, tea tree oil, duct tape or similar remedies clear molluscum. Acids and essential oils can cause chemical burns and contact dermatitis, particularly on a child’s skin, and inflamed skin can spread the virus further. When a home remedy appears to work, the most likely explanation is that the bumps were already resolving on their own, as most do within 6 to 12 months according to the CDC.

Why do molluscum bumps turn red and swollen before they go away?

Redness and swelling around a bump usually mean the immune system has recognized the virus and is clearing it. This inflammatory phase can last a week or two and often looks worse before the bump shrinks and disappears. It is frequently mistaken for infection. True bacterial infection differs: spreading warmth, pus, increasing pain, or fever. If those features appear, or if you are unsure, contact the treating clinician.

Should adults with genital molluscum be treated?

Treatment is more often offered for genital molluscum in adults because the bumps are readily passed to partners and because the area is uncomfortable and socially distressing. A sexual health assessment is usually advised at the same time, since other infections can be present alongside. Cryotherapy and curettage are commonly used; some topical agents are avoided on genital skin. Avoiding sexual contact until bumps have resolved reduces spread. The treating clinician decides the approach.
