Laser, Microneedling or Radiofrequency for Stretch Marks: How Dermatologists Choose the Method

She noticed them in a changing-room mirror, under lighting nobody would choose: a fan of silvery lines across each hip, left behind by a growth spurt at fifteen and a pregnancy at thirty. The internet offered her a cream that promised to erase them, a celebrity who apparently had none, and three clinical words she did not fully understand. Laser. Microneedling. Radiofrequency.

Behind those words sits a surprisingly orderly decision. When a dermatologist looks at stretch marks, they are not asking which machine is newest. They are asking how old the marks are, what color they are, how the surrounding skin tends to heal, and what the person in front of them can realistically live with for the next few weeks. Seeing stretch mark treatment options compared side by side, the way a clinician actually weighs them, makes the choice far less mysterious.

This explainer walks through that reasoning, including the parts marketing tends to leave out.

What a stretch mark actually is, and why removal is the wrong word

A stretch mark, which doctors call a stria, is a scar that forms inside the skin rather than on its surface. When skin is stretched faster than it can adapt, the dermis (the middle layer that gives skin its strength and bounce) tears in a controlled way. Collagen, the protein that acts like scaffolding, and elastin, the fibers that let skin snap back, are disrupted and then laid down again in a thinner, flatter pattern. The result is a line that looks and feels different from the skin around it, even after it heals.

That word, scar, is the key to everything that follows. Scars can be softened, flattened and made less visible. They cannot be un-made. The NHS is direct about this: stretch marks usually fade over time and treatment is unlikely to remove them completely. Mayo Clinic says the same, adding that stretch marks are harmless and need no treatment at all unless their appearance troubles you.

They are also extraordinarily ordinary. The NHS estimates that around 8 in 10 women develop stretch marks during pregnancy, and Cleveland Clinic notes that estimates for the general population run from roughly half to 90 percent of people. Puberty, rapid muscle gain, weight change, corticosteroid medicines and certain genetic conditions all count as triggers, according to Mayo Clinic and MedlinePlus.

So the honest question is never how to erase stretch marks. It is how to reduce their contrast and texture enough that they stop catching your eye, using the method that best fits your marks and your skin. That reframing is the first thing a good clinician offers, before any device is switched on.

Stretch mark treatment options compared at a glance

Three energy-based approaches dominate modern stretch mark care, and each nudges the skin toward repair in a different way. Laser uses focused light. Microneedling uses tiny mechanical punctures. Radiofrequency uses electrical energy that heats tissue from within. A clinician’s choice depends on what the mark needs most: color correction, collagen rebuilding, or both.

Method	What it does	Usually chosen for	Main trade-off
Vascular or non-ablative fractional laser	Targets redness and stimulates collagen with columns of light, skin surface mostly intact	Newer red or purple marks; lighter to medium skin tones	Multiple sessions; light-based methods carry more pigment risk in deeper skin tones
Ablative fractional laser	Vaporizes microscopic columns of skin to trigger deeper remodeling	Older, wide, textured white marks	Longest downtime; highest pigment and scarring risk
Microneedling	Fine needles create controlled micro-injuries that prompt new collagen	White marks; all skin tones, including darker skin	Course of repeated sessions; gradual, modest change
Radiofrequency microneedling	Needles deliver heat directly into the dermis, bypassing the surface	Textured, indented marks; skin tones where lasers feel risky	Newer evidence base; sessions repeated

Reading the table from left to right, notice what does not appear: a winner. The columns describe fit, not ranking. A method that is ideal for a fresh red mark on fair skin can be the wrong tool for a decade-old white mark on deep brown skin. That is why two friends with similar marks can leave the same clinic with different plans, and why comparison lists online that crown one technique as best are quietly misleading.

The rest of this article unpacks each row, then shows how a clinician moves through them.

How laser treatment for stretch marks works

Picture sunlight through a magnifying glass, but tuned. A laser emits one wavelength of light, and different wavelengths are absorbed by different things in the skin. Some are soaked up by hemoglobin, the red pigment in blood. Others are absorbed by water, which every skin cell is full of. Dermatologists exploit this selectivity.

For a fresh, red or purple stretch mark, the redness comes from tiny dilated blood vessels in the injured dermis. A vascular laser sends light that hemoglobin absorbs, gently heating and collapsing those vessels so the mark blanches toward skin color. This does little for texture, but color is often what makes a new mark so visible.

For older marks, clinicians turn to fractional lasers. Fractional means the beam is split into a grid of microscopic columns, treating perhaps a fraction of the surface while leaving untouched skin between the dots. Those healthy islands speed healing. Non-ablative fractional lasers heat the dermis without breaking the surface, coaxing fibroblasts (the cells that make collagen) into producing new, better-organized fibers. Ablative fractional lasers go further, vaporizing the columns entirely, which triggers stronger remodeling at the cost of open micro-wounds and more recovery.

Mayo Clinic lists light and laser therapies among the options that may improve the appearance of stretch marks, while stressing they do not remove them. The mechanism explains why. Lasers persuade the skin to reorganize its scar; they do not replace scar with virgin dermis. Results build over weeks as collagen matures, and several sessions are typical, spaced to let the skin recover between them. Your clinician will set that spacing based on how your skin responds.

How microneedling for stretch marks works

Microneedling is almost disarmingly simple. A handheld device studded with very fine, sterile needles is rolled or stamped across the numbed skin, creating thousands of tiny channels that reach into the dermis. Each puncture is a controlled injury, too small to scar but large enough to sound an alarm. The skin responds the way it responds to any wound: platelets release growth factors, fibroblasts arrive, and new collagen and elastin are laid down over the following weeks.

The elegance is that nothing is heated and nothing is removed. Because microneedling does not rely on light being absorbed by pigment, it carries a lower risk of unwanted darkening or lightening than lasers, which is why dermatologists often favor it for deeper skin tones. Cleveland Clinic describes it as a treatment used for stretch marks and other textural scars, performed as a course of repeated sessions rather than a single visit, with redness that typically settles over a few days.

What microneedling does well is texture. The slightly sunken, crinkly surface of an old white mark can become flatter and more even as new collagen fills in beneath it. What it does less well is color. It will not blanch a red mark the way a vascular laser can, and it will not restore pigment to a white one, though some clinicians combine it with other approaches for that reason.

Expect gradual change. Collagen remodeling continues for months after a session, so the picture at week two is not the final picture. Your care team will judge whether to continue after seeing how the first few treatments settle.

How radiofrequency and RF microneedling treat stretch marks

Radiofrequency, usually shortened to RF, uses electrical energy at a frequency that passes through skin and generates heat in the tissue it meets. Unlike a laser, that heat does not depend on color. It does not care whether the skin is fair or deep brown, or whether the mark is red or white. This single property explains much of its appeal.

Two forms exist. Surface RF devices heat the dermis through intact skin, aiming to tighten existing collagen and stimulate new fibers. The effect is gentle and tends to suit mild, shallow marks. RF microneedling combines the two ideas discussed above: insulated needles enter the skin and release radiofrequency energy from their tips, placing heat precisely at the depth where the scar tissue sits while sparing the surface. The result is deeper remodeling than plain microneedling with less surface disruption than an ablative laser.

Dermatologists often reach for RF microneedling when a mark is wide, indented and textured, and when the person’s skin tone makes light-based treatments a pigment gamble. Because the surface is largely bypassed, the risk of post-inflammatory hyperpigmentation (darkening after inflammation) is generally considered lower than with ablative lasers, though it is not zero.

Honesty is due here. Radiofrequency for stretch marks has a younger and thinner evidence base than lasers or conventional microneedling. Studies exist and many report improvement in texture, but they tend to be small and short, and they vary in how they measure results. Mainstream references such as Mayo Clinic and the NHS do not list RF as a standard first-line option in the way they list laser and microneedling. That does not make it ineffective; it means the claim should be stated as promising rather than proven, and discussed with a clinician who uses it regularly.

Laser vs microneedling for stretch marks: which is better?

This is the question most people arrive with, and the honest answer is that it depends on three things your dermatologist can see and you may not.

The first is color. A red or purple mark is still inflamed and vascular, and a laser that targets hemoglobin can address that directly. Microneedling cannot. For fresh marks, laser often leads.

The second is skin tone. Lasers work by light absorption, and melanin, the pigment that gives skin its color, absorbs light too. In deeper skin tones, some of the energy meant for the scar is captured by pigment in the surrounding skin, raising the risk of patches that end up darker or lighter than before. Microneedling sidesteps that physics. For many people with medium to deep skin, microneedling or RF microneedling is the safer first choice, and clinicians will often say so plainly.

The third is downtime and depth. Ablative fractional laser delivers the strongest remodeling for old, wide, indented marks, but it means days of raw, weeping skin and strict sun avoidance. Microneedling asks for a few days of redness and can be repeated more comfortably. Non-ablative fractional laser sits between the two.

Head-to-head evidence is limited. Small comparative studies have found both methods improve the appearance of striae, with differences that are modest and inconsistent between trials. No major guideline body declares one superior. That is not a cop-out; it reflects the data. The practical conclusion is that the best method is the one matched to your mark and your skin, delivered by someone experienced with that device, with expectations set for improvement rather than disappearance.

Red stretch marks vs white stretch marks: why color drives the plan

Ask a dermatologist the single most useful thing to know before treatment, and many will say: look at the color.

New stretch marks, called striae rubrae, are red, pink or purple. They may be slightly raised and can itch. Under the surface, the dermis is inflamed, blood vessels are dilated, and the collagen network is still actively reorganizing. This is a window. Tissue that is still remodeling is more responsive to intervention, which is why vascular lasers and non-ablative fractional treatments tend to show their best results on red marks. Mayo Clinic notes that treatments generally work better on newer marks than on old ones.

Over months to years, the inflammation resolves and the marks mature into striae albae: white or silvery, flat or slightly sunken, with a fine wrinkled surface. The blood vessels have gone, so there is no redness to target. Pigment-producing cells are sparse in the scar, which is why it looks pale against tanned or darker skin. Collagen has settled into a stable, thin arrangement that is harder to persuade into change. White marks respond to fractional lasers, microneedling and RF microneedling, but more slowly and more modestly.

This does not mean old marks are hopeless. It means the goals shift. With red marks, a clinician may aim to reduce color and prevent the mark from maturing as visibly. With white marks, the aim is to improve texture and soften the border so the eye slides past. Some clinicians also discuss approaches to encourage pigment return in pale marks, though evidence there is thinner.

If you are deciding whether to act now or later, color is the clock worth watching, together with your clinician’s view of your skin’s healing tendencies.

Who is usually a candidate, and who is usually asked to wait

Good candidates share a few traits: their skin heals predictably, they are not pregnant or breastfeeding, their weight is reasonably stable, and they understand that the goal is improvement. Beyond that, the specifics of the mark and the skin guide the method, as earlier sections describe.

Several groups are commonly asked to wait or to choose differently. Pregnancy tops the list. Energy-based treatments are generally deferred until after delivery, and the NHS notes that the marks themselves often fade naturally in the months afterward, so treating during pregnancy would be both premature and poorly studied. Retinoid creams, which Mayo Clinic lists as a possible option for newer marks, are avoided in pregnancy because of concern about effects on the developing baby; that decision rests with the prescribing clinician.

People who have recently taken oral retinoid medicines for acne are often asked to wait before ablative procedures, because of concern about impaired healing. Anyone with a history of keloid or hypertrophic scarring (raised, overgrown scars) needs careful discussion, since any treatment that injures skin could provoke the same response. Active skin infection, uncontrolled diabetes, or conditions that affect wound healing are reasons to pause.

Skin tone is not a barrier but a steering factor. Deeper skin tones are more prone to post-inflammatory pigment change, so clinicians often favor microneedling or RF microneedling over ablative laser, and may test-treat a small area first.

Someone in the middle of rapid weight change or muscle building is usually advised to let their body settle. Treating marks that are still being stretched is a little like repainting a wall that is still moving. Timing, in this field, is its own kind of treatment.

What the following days and weeks usually look like

Recovery differs more between methods than most people expect, and it is often the deciding factor once safety and fit are settled.

After microneedling, the treated skin typically looks like a moderate sunburn: pink, warm, faintly swollen, sometimes with pinpoint spots of dried blood. Cleveland Clinic describes redness that generally eases within a few days, and many people resume normal activities the next day while avoiding heavy exercise, hot baths and direct sun until the skin calms. Gentle cleansing and a bland moisturizer are the usual instructions.

Non-ablative fractional laser tends to produce a few days of redness and a rough, sandpaper feel as tiny treated columns shed. Ablative fractional laser is a different experience: the skin weeps, crusts and peels over roughly a week or more, with pinkness that can linger for weeks. Wound care matters, and strict sun protection continues for months, because freshly remodeled skin darkens easily.

RF microneedling usually sits closer to plain microneedling in downtime, with redness and mild swelling for a few days, though deeper settings can extend that.

Across all three, the visible change arrives late. Collagen remodeling continues for weeks to months after each session, so improvement at the two-week check is only a preview. Clinicians typically schedule sessions with enough gap for the skin to finish one healing cycle before the next begins; your team will set that interval rather than any generic calendar.

Photographs help. Because change is gradual and marks are often somewhere you cannot see easily, standardized before-and-during photos taken by the clinic are the fairest way to judge progress. Memory is a poor instrument for measuring a hip.

Do stretch mark creams work? Retinoids, hyaluronic acid and the rest

Most people try a cream before they ever see a dermatologist, so it is worth being clear about what the shelf can and cannot do.

Prescription retinoids, a class of vitamin A derived medicines, are the only topical approach with reasonable evidence for stretch marks, and even that is limited to newer, red marks. They work by speeding skin cell turnover and stimulating collagen production in the dermis. Mayo Clinic lists retinoid cream as an option that may help improve the appearance of recent stretch marks, while noting it is unlikely to help mature white ones and must be avoided in pregnancy and breastfeeding. Whether it suits you, and for how long, is a decision for the prescribing clinician; irritation is common early on.

Hyaluronic acid, a molecule that holds water in the dermis, has some small studies suggesting modest benefit on early marks when massaged in regularly. The evidence is thin and the effect, where seen, is small.

Cocoa butter, almond oil, olive oil, vitamin E and the many products marketed for prevention have been studied, mostly in pregnancy. The NHS states plainly that there is little evidence creams or oils prevent stretch marks. Massaging them in is harmless and pleasant, and moisturized skin may itch less, but the marks appear or do not largely according to genetics and how fast the skin is stretched.

Self-tanners and body makeup do nothing to the mark itself but can reduce contrast for an event, which the NHS mentions as a legitimate camouflage option. That is not treatment, but it is honest, and sometimes it is enough.

How to get rid of stretch marks: what the evidence honestly shows

Type that phrase into a search bar and the results promise a lot. The medical literature promises considerably less, and the gap deserves a straight explanation.

Three mainstream sources agree on the ceiling. The NHS says treatments are unlikely to get rid of stretch marks completely. Mayo Clinic says none of the available treatments removes stretch marks, though some may improve their appearance. Cleveland Clinic frames the aim as making marks less noticeable. These are not cautious lawyers talking; they are summarizing what happens when scar tissue is treated.

What the evidence does support is improvement. Reviews of laser, microneedling and radiofrequency studies consistently report reductions in redness, width and textural irregularity, with participants and blinded assessors rating marks as less visible after a course of treatment. The size of that improvement varies widely between studies, depends heavily on whether marks were red or white, and is measured with tools that differ from one trial to the next. No guideline body publishes a percentage you could reasonably apply to your own skin, so this article will not invent one.

Equally well supported is the tendency of stretch marks to fade on their own. The NHS notes that marks usually become paler and less noticeable over time, particularly after pregnancy. Some of what a treatment appears to achieve in the first year after a mark forms would have happened anyway, which is one reason clinicians photograph carefully and avoid promising outcomes.

Where does that leave someone weighing stretch mark treatment options compared against simply waiting? With a genuine choice, not a false one. Treatment can accelerate and deepen an improvement that nature offers slowly and partially. It cannot deliver skin that was never stretched.

What people often get wrong about stretch mark treatment

Myths cluster around stretch marks the way they cluster around anything visible and common. A few are worth correcting directly.

The first is that a celebrity’s smooth skin proves a method works. Photographs are lit, retouched, tanned and posed; the person in them may have had treatment, may have used body makeup, or may simply have genes that spared them. No public medical record exists for what any famous person did about their stretch marks, and even if it did, their skin type, mark age and healing response would not be yours.

The second is that another country holds a secret. The idea that people in one nation have discovered how to remove stretch marks does not survive contact with the evidence. Clinics everywhere use the same categories of laser, microneedling and radiofrequency described here, drawn from the same published studies. Skincare cultures that emphasize hydration and sun protection may keep skin looking healthier, which is a fine habit, but it does not undo a dermal scar.

The third is that more aggressive is better. Deeper settings and more ablation raise the risk of pigment change and new scarring, especially in deeper skin tones. The right intensity is the one your skin can heal from cleanly.

The fourth is that a cream prevented someone’s marks. Prevention studies are largely negative, as the NHS summarizes; the person who used a butter through pregnancy and has no marks most likely has skin that would not have marked anyway.

The last is that men do not get them, or that only weight gain causes them. Puberty, bodybuilding, corticosteroid medicines and genetic connective tissue conditions all cause striae, according to Mayo Clinic and MedlinePlus, in every gender and at every size.

Questions to ask your care team before choosing a method

A consultation is more useful when you walk in with questions rather than a preference for a device. These are the ones that tend to change decisions.

• Which of my marks are still red or purple, and which have matured? Does that change what you would start with?
• Given my skin tone, what is my risk of darkening or lightening, and would you test a small area first?
• Are you recommending laser, microneedling or radiofrequency for my marks specifically, and what makes that the better fit than the others?
• How many sessions do you anticipate, how far apart, and at what point would you reassess whether to continue?
• What will my skin look and feel like in the first week, and what activities should I avoid?
• How will we measure improvement? Will you take standardized photographs?
• Are there reasons in my history, such as past keloids, recent oral retinoid use, pregnancy plans or medicines I take, that mean I should wait?
• If I do nothing, how would you expect these marks to change over the next year or two on their own?
• What would make you stop treatment or switch methods?
• Who do I contact if something looks wrong afterward, and how quickly?

Notice what these questions do. They move the conversation from which treatment is best in the abstract to which is right for this skin, these marks and this life. A clinician who welcomes them is telling you something about how they practice.

Bring a list of everything you apply to your skin and every medicine you take, including supplements. Some topical acids and oral medicines affect how skin heals, and your team will want to plan around them.

When to call your doctor

Stretch marks themselves are harmless, and most treatment recovery is uneventful. A few situations do warrant a prompt call rather than watchful waiting.

After any laser, microneedling or radiofrequency session, contact your care team the same day if you notice spreading redness beyond the treated area, increasing rather than easing pain, pus or cloudy discharge, blistering, a fever, or skin that turns unexpectedly dark, gray or white in patches. These can signal infection, a burn or an early pigment change, and all are easier to manage when caught early. Cold sores or other rashes appearing in the treated zone also need a quick review.

Separately from treatment, new stretch marks deserve a medical look when they appear without an obvious cause. Mayo Clinic and MedlinePlus list corticosteroid medicines and Cushing syndrome, a condition of excess cortisol, among causes of striae. Wide purple marks arriving alongside unexplained weight gain around the trunk, a rounded face, easy bruising, muscle weakness or high blood pressure should prompt an appointment with your doctor, who may check hormone levels. Widespread striae in a child or teenager who is not growing rapidly, or marks accompanied by very stretchy skin and joints that dislocate easily, can point toward inherited connective tissue conditions that a clinician should assess.

Finally, if the appearance of your stretch marks is affecting your mood, your relationships or your willingness to swim, exercise or be intimate, that is a legitimate reason to see a doctor too. Body image distress is treatable, and a good clinician will take it as seriously as the marks themselves. Every decision about whether and how to treat sits with you and your treating team, not with a search result.

Frequently asked questions

What is the most effective stretch mark treatment?

There is no single most effective treatment; the right method depends on the mark’s color and age, your skin tone and your tolerance for downtime. Vascular and non-ablative lasers suit red marks, while fractional laser, microneedling and radiofrequency microneedling target white marks. Mainstream sources agree all methods improve appearance rather than remove marks.

Which is better, laser or microneedling for stretch marks?

Neither is better across the board. Laser can reduce redness and remodel collagen but carries more pigment risk in deeper skin tones. Microneedling improves texture with lower pigment risk and shorter downtime but cannot blanch red marks. Small comparative studies show both help, with modest and inconsistent differences, so fit matters more than ranking.

How did Kim Kardashian get rid of stretch marks?

No verified medical account exists of what any celebrity did about stretch marks, and interviews or social posts are not clinical records. Photographs are also lit, posed and often retouched. Even if a specific procedure were confirmed, another person’s mark age, skin tone and healing response would not predict your outcome.

How do Koreans get rid of stretch marks?

There is no national secret. Clinics in Korea, as elsewhere, use the same categories of laser, microneedling and radiofrequency described in published research. Korean skincare culture emphasizes hydration and sun protection, which supports healthy-looking skin but does not undo a dermal scar. Choosing a treatment should rest on your skin and a local clinician’s assessment.

What is radiofrequency microneedling for stretch marks?

It combines fine needles with radiofrequency energy released at the needle tips, heating the dermis precisely where scar tissue sits while sparing the surface. Because it does not rely on light absorption, it is often considered for deeper skin tones and textured marks. Evidence is promising but comes from smaller, shorter studies than those for laser or plain microneedling.

Can stretch marks be removed completely?

No. The NHS states treatments are unlikely to get rid of stretch marks completely, and Mayo Clinic says none of the available options removes them. Because a stretch mark is a scar within the skin, the realistic goal is reduced redness, flatter texture and less contrast with surrounding skin.

Is the best treatment for stretch marks different during and after pregnancy?

Yes. Energy-based treatments and retinoid creams are generally avoided during pregnancy and breastfeeding, with the decision left to the treating clinician. The NHS notes that around 8 in 10 women develop stretch marks in pregnancy and that they usually fade afterward, so clinicians often suggest waiting several months postpartum before assessing what remains.

How long does it take to see results from stretch mark treatment?

Visible change is gradual because collagen remodeling continues for weeks to months after each session. Redness from microneedling typically settles within a few days, according to Cleveland Clinic, while ablative laser recovery takes longer. Clinicians usually schedule several sessions and judge progress with standardized photographs rather than at the first follow-up.

Do stretch mark creams really work?

Prescription retinoid creams have modest evidence for newer red marks, according to Mayo Clinic, and are avoided in pregnancy. Over-the-counter butters, oils and vitamin E have little evidence for treatment or prevention, as the NHS summarizes. Moisturizing can ease itching and self-tanner can reduce contrast, but neither changes the scar itself.

Are stretch mark treatments safe for darker skin?

They can be, with the right method. Lasers work by light absorption, and melanin absorbs light too, raising the risk of darker or lighter patches in deeper skin tones. Dermatologists therefore often favor microneedling or radiofrequency microneedling, use conservative settings, and may test a small area first. Strict sun protection afterward matters for everyone.
