Who Is a Candidate for Laser Resurfacing? Skin Tone, Recent Tanning and Healing History

She had already paid for the beach week before the consultation was booked, and she arrives with the tan to prove it: a faint line at the strap, a glow on the cheekbones that would look lovely in photographs. The clinician glances at it and gently moves the conversation away from the laser and toward a question she had not expected: how did your skin heal after that appendix scar?

That small pivot sums up how laser resurfacing candidates are actually chosen. The lines or the acne marks matter, but so do the quieter facts: how your skin responds to sun, how it mends, whether cold sores visit when you are run down, which medicines you have taken in the past year.

None of those details is a verdict. Each one changes the odds of a smooth recovery, and a careful team weighs them before any device is switched on.

What laser resurfacing actually does to the skin

Laser resurfacing is a procedure in which a focused beam of light is used to remove or heat the outer layers of skin so that new, more evenly textured skin forms as the area heals. The light is absorbed mainly by water inside skin cells, which converts it to heat. What happens next depends on the type of laser.

Ablative lasers vaporize the thin surface layer (the epidermis) and heat the layer beneath (the dermis). The heat causes collagen fibers, the protein scaffolding that gives skin its firmness, to tighten and prompts the body to produce more over the following weeks. Carbon dioxide and erbium lasers belong to this group. Because the surface is removed, the treated area is effectively a controlled wound until it re-epithelializes, the medical term for new surface skin growing back.

Nonablative lasers leave the surface intact and heat only the deeper layer. There is no open wound, recovery is shorter, and the change is gentler, which is why these treatments are often repeated in a series. Both ablative and nonablative devices can be delivered in a fractional pattern, meaning the beam is split into thousands of microscopic columns that treat a fraction of the skin and leave untouched skin between them. Those untreated islands act as reservoirs of healthy cells, and the Mayo Clinic notes that fractional approaches shorten recovery compared with treating the whole surface.

Why does any of this matter for candidacy? Because the deeper and more complete the injury, the more the outcome depends on your skin’s own repair machinery. A tan, a tendency to scar thickly, a dormant virus or a drug that slows wound healing all act on exactly that machinery. The assessment is less about whether the laser can reach your wrinkles and more about whether your skin can be trusted to rebuild afterward.

Who are the usual laser resurfacing candidates, and who is asked to wait?

Most people referred for resurfacing share a short list of features. They have a concern the laser can plausibly address, such as fine lines around the eyes or mouth, sun-damaged or mottled skin, enlarged pores, uneven texture, or certain acne or surgical scars. Their skin is currently calm, with no active infection or flare of a skin condition. They are not tanned. They understand that results arrive gradually and that redness is part of the process. And they can commit to strict sun protection before and after treatment.

The people who are usually asked to wait, or to consider a different approach, are not being judged. They simply carry one or more factors that the Mayo Clinic and Cleveland Clinic list as raising the chance of a complication: a recent tan, isotretinoin use within roughly the past year, a history of keloid scarring, active acne or a current cold sore, previous radiation therapy to the face, or a very deep natural skin tone being considered for a fully ablative treatment.

Factor	Usually proceeds	Usually asked to wait or reconsider
Skin tone	Lighter to medium tones; darker tones with adjusted settings	Deepest tones for fully ablative treatment
Sun	No tan, consistent sunscreen use	Visible tan or sunburn
Healing history	Previous scars flat and faded	Keloids or thick raised scars
Infections	No active lesions	Current cold sore, acne flare or skin infection
Medicines	No recent isotretinoin; stable prescriptions reviewed	Isotretinoin in the past year; unreviewed drugs that affect clotting or immunity
Expectations	Wants gradual improvement	Expects a single session to erase deep lines

Treat the table as a map of the conversation, not a scoring sheet. A clinician may proceed with one risk factor and decline with another, because context, laser type and depth of treatment all shift the balance.

Laser resurfacing for dark skin: what the evidence says about pigment risk

The most searched question about laser resurfacing candidates concerns skin tone, and the honest answer has two halves. Darker skin can be treated. Darker skin also carries a higher risk of a specific complication, and the decision turns on how that risk is managed.

Clinicians often describe tone using a skin phototype scale (the Fitzpatrick scale), which groups skin by how readily it burns or tans in the sun rather than by ethnicity. Skin with more melanin, the pigment that gives skin its color, has pigment-producing cells that react more vigorously to injury and inflammation. After a laser wound those cells may overproduce pigment, leaving darker patches, or they may underproduce it, leaving lighter ones. The Mayo Clinic lists these color changes among the recognized risks of resurfacing and notes they are more likely in people with darker skin. The Cleveland Clinic makes the same point and describes post-inflammatory hyperpigmentation, the darkening that follows any skin injury, as more common in people of color.

What changes in practice? Several things. Nonablative or fractional devices, which spare the surface and reduce total heat, are generally preferred over fully ablative treatment in deeper tones. Energy settings are lowered and the treated fraction reduced. Many clinicians start with a test patch in a discreet area and wait several weeks to see how pigment responds. Sun avoidance is enforced more strictly, since ultraviolet exposure further stimulates pigment cells during healing. Some teams also use pigment-calming topical preparations before and after treatment; whether and how that applies to you is a prescribing decision for your clinician.

The line that matters most is this: skin tone is a reason to adjust the plan, rarely a reason to refuse it outright, and a clinician experienced with a wide range of skin tones will usually say so clearly rather than quoting a single rule for everyone.

Laser resurfacing after tanning: why even a light tan changes the plan

A tan is a visible record of recent sun exposure, and it tells the clinician two things at once. First, the skin’s pigment cells are currently switched on and producing extra melanin. Second, the barrier has recently been stressed by ultraviolet light, even if nothing burned.

Both facts matter. Laser energy is absorbed by chromophores, the molecules in tissue that take up light, and melanin is one of the strongest. More melanin in the surface means more energy is captured there rather than in the target layer below, which can cause uneven heating, blistering, and the same pigment changes that worry teams treating darker skin tones. A tan temporarily moves lighter skin further along the risk spectrum, and it does so unpredictably, because the tan is uneven and fading.

This is why the Mayo Clinic advises avoiding unprotected sun exposure for a period before and after resurfacing, with the organization specifically describing a window of up to a year before and after for people prone to pigment problems, and why most teams will simply postpone when a tan is present. Sunless tanning products deserve a mention too: they stain the outer skin layer and can affect how the surface absorbs light and how the clinician judges the skin’s true tone, so most teams ask that they be stopped well before treatment and fully faded.

Sunburn is a firmer stop. The NHS describes sunburn as a radiation injury that leaves skin inflamed and sometimes blistered; layering a laser wound on top of that is not something a careful clinician will do. The practical message is unglamorous but clear. If you are considering treatment, the preparation starts with shade, hats and broad-spectrum sunscreen weeks ahead of the appointment, and it continues long after the redness fades.

Healing history: keloids, raised scars and past radiation

Here is the question from the opening scene, and it is worth taking seriously. How your skin closed its last wound is one of the best clues to how it will close the next one.

A keloid is a scar that keeps growing beyond the edges of the original injury, forming a firm, raised, sometimes itchy or tender mound. MedlinePlus describes keloids as more common in people with darker skin and notes that they can follow surgery, piercings, burns, acne or even minor scratches. Hypertrophic scars are raised too, but they stay within the original wound boundaries and often flatten over time. Both patterns indicate that the person’s fibroblasts, the cells that lay down collagen during repair, respond to injury with more enthusiasm than the situation requires.

Ablative resurfacing creates a broad, shallow wound across the face. In someone with a keloid tendency, that is precisely the kind of injury that can trigger abnormal scarring across a large, highly visible area, which is why the Mayo Clinic lists a history of keloids among the reasons a clinician may advise against the procedure. Nonablative or very conservative fractional treatment may still be considered in some cases, usually after a test patch and a frank discussion of the trade-off.

Previous radiation therapy to the face is a separate concern. Irradiated skin has fewer functioning sweat glands and hair follicles, and those structures are the reservoirs from which new surface skin regrows after an ablative wound. Fewer reservoirs mean slower, less reliable healing. Clinicians also ask about any skin condition that produces new lesions at sites of injury, such as psoriasis or vitiligo, since resurfacing can provoke a flare in the treated area.

Bring your scar history to the consultation in detail: where, how old, how it looked at its worst and how it looks now. Photographs on your phone are genuinely helpful.

Cold sores, acne and infections: the quiet reasons teams say not yet

Cold sores are caused by herpes simplex virus, which after the first infection stays dormant in nerve cells and can reactivate when the skin or the immune system is stressed. MedlinePlus notes that triggers include sun exposure, illness and skin injury. Laser resurfacing is a substantial skin injury, and a reactivation across freshly treated skin is not a minor nuisance: the virus can spread over the open surface, delay healing and leave scars.

For that reason, the Mayo Clinic describes two standard precautions. Anyone with an active cold sore or other visible infection is asked to wait until it has fully cleared. And people with a history of cold sores are commonly prescribed a preventive course of antiviral medicine around the time of treatment, a class of drug that blocks the virus’s ability to copy itself. Whether that applies to you, and for how long, is a decision for the prescribing clinician; the point for candidacy is that forgetting to mention your cold sore history can turn a routine recovery into a complicated one.

Acne works similarly. Active, inflamed breakouts mean the skin is already dealing with bacteria and inflammation, and resurfacing can worsen both. Teams usually prefer to treat acne scars once the acne itself is quiet. The Cleveland Clinic also lists bacterial infection among the possible complications of resurfacing, and any current skin infection, including impetigo or an infected hair follicle, is a reason to postpone.

One more category deserves a mention. Conditions that weaken the immune system, or medicines that suppress it, reduce the body’s capacity to control the ordinary bacteria living on skin once the barrier is removed. This does not automatically rule anyone out, but it changes the monitoring plan, the choice of device and sometimes the timing, and it is information the laser clinician needs from you rather than something to assume is already in the notes.

Medicines and health conditions that change the picture

The medication history matters as much as the skin exam, and three groups come up repeatedly.

Isotretinoin is an oral retinoid used for severe acne. It shrinks oil glands and alters how skin cells mature, and those effects persist for months after the last capsule. Because of long-standing reports of poor healing and abnormal scarring after procedures in recent users, the Mayo Clinic lists having taken isotretinoin in the past year as a reason a clinician may decline to perform resurfacing. The usual advice is a waiting period, with the exact interval decided by the treating team based on the depth of the planned procedure.

Medicines that affect clotting, including some over-the-counter pain relievers, certain supplements and prescribed anticoagulants, can increase bruising and pinpoint bleeding from treated skin. The Mayo Clinic notes that your clinician may ask about these before treatment. The correct response is to list everything you take and let the prescribing clinician decide what, if anything, changes; never pause a prescribed medicine on your own, because the condition it treats can carry far more risk than the laser.

Topical retinoids, exfoliating acids and other active skincare are a gentler version of the same issue. They thin the outer layer and heighten sensitivity, so teams often ask for a pause in the days before treatment and a careful reintroduction afterward.

Underlying conditions complete the picture. Poorly controlled diabetes slows wound healing and raises infection risk. Autoimmune diseases, and the immunosuppressing drugs used to manage them, do the same. Pregnancy is generally a reason to defer elective skin procedures, partly because pregnancy hormones themselves stimulate pigment cells. None of these is a secret disqualifier. They are variables, and the more complete the information you give, the more precisely the team can set the plan or advise waiting.

Smoking, sun habits and the expectations conversation

Two lifestyle factors have an outsized effect on resurfacing outcomes, and both are within reach of change.

Smoking narrows small blood vessels and lowers the oxygen available to healing tissue. Nicotine does the same even when it arrives through a vape or a patch. The Mayo Clinic advises people who smoke to stop for a period before and after resurfacing, describing a window of about two weeks on either side, because healing skin depends on a brisk blood supply to rebuild its surface and lay down orderly collagen. Clinicians will sometimes decline fully ablative treatment in someone who cannot or does not wish to stop, and will more often steer toward a lighter approach.

Sun habits are the long game. Resurfaced skin is new skin, and new skin burns and pigments easily. The investment of recovery is quickly undone by unprotected exposure, and the risk of patchy darkening remains elevated for months. Someone whose work or hobbies keep them outdoors without reliable shade may be a better candidate in a season when that can change, and a clinician will say so.

Then there is the conversation about what the procedure can and cannot do. Laser resurfacing improves surface texture, fine lines and some discoloration. It does not lift sagging tissue, remove deep folds caused by volume loss, or change the underlying bone structure of the face. The Cleveland Clinic is explicit that results vary between people and that deeper concerns may need a different approach altogether. A good candidate hears that and still wants to proceed; a poor fit is someone expecting a single session to deliver what a surgical procedure might, because that person will be disappointed regardless of how well the skin heals.

Ask yourself a plain question before the consultation: if the change were modest but real, would it still have been worth the recovery? Your answer is useful data for the clinician.

What a thorough assessment of laser resurfacing candidates looks like

The consultation should feel less like a sales meeting and more like a medical history taken by someone who is genuinely curious about your skin. The NHS, in its guidance on cosmetic procedures, advises checking that whoever treats you is a registered healthcare professional with specific training in the procedure, and that you are given time to think before committing.

Expect the following. A review of your full medical history, including skin conditions, autoimmune disease, diabetes, pregnancy plans and every medicine and supplement. Direct questions about isotretinoin, cold sores, previous scars and any past skin procedures or radiation. A look at your skin under good light to assess tone, sun damage, active lesions and the specific concern you came in with. Photographs taken for the record. A discussion of which type of laser is being proposed and why, how deep it will go, and what the alternatives are.

Many clinicians perform a test spot: a small area, often behind the ear or at the hairline, treated with the planned settings and reviewed after several weeks. The Cleveland Clinic describes this as a way to see how an individual’s skin, particularly darker skin, responds before committing the whole face. A test spot adds time to the process, which is exactly why it is reassuring; a team willing to wait is a team watching for problems rather than rushing past them.

You should also leave with written aftercare instructions, a plan for sun protection starting now, any prescriptions the clinician judges necessary, and a clear way to reach the team if something seems wrong during recovery. If any of those elements is missing, or if your questions about risk are met with reassurance rather than specifics, that is a reason to pause, regardless of how suitable your skin appears.

Laser skin resurfacing recovery time: what the days and weeks usually look like

Recovery is where candidacy proves itself, and it is also where the gap between ablative and nonablative treatment is widest.

After ablative resurfacing the treated skin is raw, swollen and often weeping in the first days. The Mayo Clinic describes a healing period of roughly one to two weeks for the surface to close, while the Cleveland Clinic notes that complete surface healing can take up to two to three weeks depending on depth. During this time the skin is typically kept covered with a protective ointment or dressing and cleaned gently as instructed. Itching is common as new skin forms. Once the surface has healed, it is pink to red, and the Mayo Clinic notes that this redness can persist for several months before settling. Makeup is usually allowed once the surface is intact, with timing set by the team. Strict sun avoidance continues throughout.

Nonablative resurfacing is a different experience. The Mayo Clinic describes swelling and redness that typically last from a few hours to a few days, and most people return to ordinary activities quickly. The trade-off is that improvement is gradual and often requires a series of sessions spaced weeks apart.

Fractional treatments of either type fall between those extremes, with recovery scaled to how much of the surface was treated.

Whatever the device, the first follow-up appointment matters. It is when the team confirms the surface is healing cleanly, looks for early signs of infection or pigment change, and adjusts care. People who travel for treatment sometimes miss this visit, which removes the safety net exactly when it is most useful. Build the follow-up into your plan before the first appointment rather than after.

Risks worth weighing before you decide

Every honest account of resurfacing includes a list of things that can go wrong, and reading it is part of becoming a good candidate. The Mayo Clinic and Cleveland Clinic describe the following.

Redness, swelling and itching are expected rather than complications, but in some people redness lasts longer than anticipated, especially after ablative treatment. Acne flares and small white bumps called milia can appear during healing, often linked to the thick ointments used to protect new skin. Infection, whether bacterial, viral or fungal, is a real risk while the barrier is open, with reactivated herpes simplex the most characteristic.

Changes in skin color are the complication that most shapes candidacy. Darkening tends to appear in the weeks after treatment and often fades slowly; lightening can develop later and may be long-lasting. Both are more likely in darker skin tones and after sun exposure.

Scarring is uncommon but can follow infection, overly deep treatment or an underlying tendency such as keloid formation. Ectropion, an outward turning of the lower eyelid, is a rare complication of aggressive treatment close to the eye.

Finally, there is the risk that the result is simply less than hoped. That is not a medical complication, but it is a predictable disappointment when expectations and procedure are mismatched.

Two things make this list useful rather than frightening. First, most of these risks are modifiable by the choices discussed throughout this article: device, depth, timing, sun protection, infection prophylaxis and honest history. Second, none of them is a reason to decide alone. The weight you give each risk is personal, and the clinician’s job is to tell you how your particular skin shifts the odds, not to decide for you whether the odds are acceptable.

Alternatives if you are asked to wait or steered elsewhere

Being told not yet is not the same as being told no, and in many cases the delay is short. A tan fades in weeks. A cold sore clears. The year after isotretinoin passes. During that time, consistent sun protection and a calm skincare routine prepare the skin for a later attempt, and the clinician may suggest a test spot once the obstacle has resolved.

When the obstacle is more durable, such as a keloid history, a very deep skin tone combined with a wish for an ablative result, or a medical condition that compromises healing, the conversation turns to alternatives. These fall into a few broad groups, and the Cleveland Clinic and Mayo Clinic describe most of them.

Lower-intensity devices include nonablative fractional lasers, intense pulsed light and radiofrequency treatments that heat deeper tissue without removing the surface. They carry lower pigment and scarring risk and are often chosen for darker skin tones, at the cost of subtler change per session.

Non-laser resurfacing includes chemical peels of varying depth, which use acids to remove surface layers, and microneedling, which creates fine controlled punctures to stimulate collagen. Superficial peels and microneedling are frequently used in skin tones where ablative lasers are avoided, though they too require sun avoidance and carry some pigment risk.

Topical treatment, including prescription retinoids and pigment-regulating agents, works slowly over months and is often used both as an alternative and as preparation for a procedure. Whether and how these are used is a prescribing decision.

For concerns the laser was never going to fix, such as sagging or deep folds from volume loss, the honest alternative may be a surgical or injectable approach, or simply the decision that the trade-off is not worth it. All of these are legitimate outcomes of a good consultation.

What people often get wrong about laser resurfacing

Some of the most persistent myths about laser resurfacing candidates come from a decade when fully ablative carbon dioxide treatment was the only option, and others come from marketing that drifts past the evidence. Five are worth correcting.

Darker skin cannot be lasered. Untrue. The risk of pigment change is higher and the approach must be adjusted, but nonablative and conservative fractional treatments are widely used across skin tones. The accurate statement is that darker skin needs a clinician experienced in treating it, not that it needs to be refused.

A light tan does not count. It does. Melanin absorbs laser energy regardless of how the tan looks in the mirror, and clinicians postpone for faint tans for the same reason they postpone for deep ones.

Nonablative means no risk. Gentler is not the same as risk-free. Pigment change and infection are less likely but not absent, and sun protection rules still apply.

If I healed well from surgery I will heal well from a laser. Often true, and a reassuring sign, but not a guarantee. A surgical scar is a narrow line; ablative resurfacing wounds a broad surface, which places different demands on repair, and isotretinoin or a new medicine can change how skin heals since that last operation.

Results are permanent. Resurfacing removes existing damage and builds new collagen, but it does not stop time or sun. The Mayo Clinic notes that as you age and if you continue sun exposure, lines and discoloration will return, which is why clinicians treat sun habits as part of the candidacy assessment rather than an afterthought.

A sixth misconception deserves a sentence: that the decision belongs to the person holding the laser. It belongs to you, informed by a clinician who has told you how your own skin changes the odds.

Questions to ask your care team

Walk into the consultation with questions written down. The quality of the answers tells you as much about your suitability as the skin exam does.

• Which type of laser are you proposing for me, and why that one rather than a gentler or stronger option?
• Given my skin tone, what is my specific risk of darkening or lightening, and what will you do to reduce it?
• Do you recommend a test spot first, and how long will you wait before reviewing it?
• How much recent sun exposure or tan is too much, and how far ahead of treatment should I start strict protection?
• I have had a cold sore before; what does that change in my plan?
• I have this scar from a previous injury or operation; does the way it healed concern you?
• I took isotretinoin or currently take these medicines and supplements; which of them matter, and who decides whether anything changes?
• What will my face look like on day two, day seven and week four, and when can I expect to return to work or social settings?
• How many sessions do you anticipate, and what happens if the first produces less change than expected?
• What signs during recovery should prompt me to call you, and how do I reach the team outside normal hours?
• What are the alternatives if you decide I should wait or should not proceed?
• What training and experience do you have treating skin like mine?

The NHS encourages people considering cosmetic procedures to take time after the consultation rather than booking on the spot, and to ask directly about the practitioner’s qualifications. A team confident in its assessment will welcome every question above, answer with specifics, and be comfortable with you going home to think. If you sense impatience with the list, treat that as information too.

When to call your doctor

Most recoveries are uncomfortable but uneventful. A small number are not, and the difference between a minor problem and a lasting one is often how quickly it is seen. Contact the team that treated you, or seek urgent care if you cannot reach them, if you notice any of the following.

Signs of infection: increasing rather than decreasing pain after the first few days, spreading redness beyond the treated area, yellow or green discharge, a foul smell, or a fever. Clusters of small fluid-filled blisters, especially with tingling or burning, can indicate herpes simplex reactivation and need same-day assessment because the virus can spread rapidly across healing skin.

Signs of abnormal healing: areas that remain open or weeping well past the expected window, thickening or raised firm tissue within the treated area, or patches that are becoming distinctly darker or lighter than surrounding skin. Early review gives the team the most options.

Eye symptoms after treatment near the eyelids: a lower lid that looks pulled down or will not close fully, persistent eye pain, or changes in vision.

Anything that frightens you. Severe swelling that makes it hard to open the eyes or mouth, difficulty breathing, or an allergic reaction to a dressing or ointment all warrant immediate medical attention.

Keep the written aftercare instructions and the team’s contact details somewhere obvious, and do not wait for the scheduled follow-up if something feels wrong before then. Resurfaced skin changes quickly in both directions, and the clinicians who treated you would far rather see a false alarm than a late presentation. The decision about what to do next, including whether any medicine is needed, rests with the treating team who can examine the skin directly.

Frequently asked questions

Who should not get laser resurfacing at all?

Firm reasons to avoid or defer include an active skin infection or cold sore, a visible tan or sunburn, isotretinoin use within roughly the past year, a history of keloid scarring, and prior radiation therapy to the face. Pregnancy and poorly controlled conditions that impair healing are usually reasons to wait. Most other factors adjust the plan rather than exclude you, and the final judgment belongs to the clinician who examines your skin.

Is laser resurfacing safe for dark skin?

It can be, with the right approach. Darker skin carries a higher risk of pigment change after any skin injury, so clinicians typically favor nonablative or conservative fractional devices, lower energy settings, strict sun avoidance and often a test spot first. Fully ablative treatment is generally avoided in the deepest tones. Experience treating a wide range of skin tones matters more than the device name.

How long after tanning can I have laser resurfacing?

There is no single number, because tans fade at different rates and clinicians judge by looking at your skin rather than counting days. The Mayo Clinic advises avoiding unprotected sun before and after treatment, describing a window of up to a year for people prone to pigment problems. Expect your team to postpone until any visible tan has fully faded and you have been protecting your skin consistently.

What is the typical laser skin resurfacing recovery time?

Ablative treatment leaves raw skin that usually takes about one to two weeks to close, and up to two to three weeks for deeper procedures, followed by redness that can last several months. Nonablative treatment typically causes swelling and redness for a few hours to a few days, with a quicker return to normal activity but a need for repeated sessions. Fractional treatments fall between the two.

Can I have laser resurfacing if I get cold sores?

Usually yes, provided there is no active sore at the time and your team knows your history. Resurfacing can reactivate the herpes simplex virus across healing skin, so people with previous cold sores are commonly given a preventive course of antiviral medicine around the procedure. Whether that applies to you, and the timing, is decided by the prescribing clinician. Any active lesion means postponing.

Why does a past keloid matter for a facial laser?

A keloid shows that your skin tends to overproduce scar tissue after injury. Ablative resurfacing wounds a broad, highly visible area, so the same tendency could produce raised scarring across the face. The Mayo Clinic lists keloid history among reasons a clinician may advise against the procedure. Some teams consider very conservative nonablative treatment after a test spot, but many prefer non-laser alternatives.

How long after isotretinoin can I have laser resurfacing?

The Mayo Clinic lists isotretinoin use within the past year as a factor that may lead a clinician to decline resurfacing, because the drug alters skin healing for months after it is stopped. The exact waiting interval is set by your treating team based on the depth of treatment planned. Tell every clinician you see that you have taken it, even if it was some time ago.

Does a test spot really predict how my face will respond?

It gives useful evidence rather than a guarantee. A small area treated with the planned settings and reviewed after several weeks shows whether your skin heals cleanly and whether pigment darkens or lightens. The Cleveland Clinic describes this as particularly helpful for darker skin tones. A reassuring test spot lowers risk; it does not remove the need for sun protection and careful aftercare.

Do I need to stop my medicines before laser resurfacing?

Never stop a prescribed medicine on your own. Some drugs and supplements affect clotting, immunity or skin healing, and your team may ask about them. Any change is a decision for the clinician who prescribed the medicine, weighed against the condition it treats. Your job is to provide a complete list, including over-the-counter products and topical skincare, so nothing is overlooked.

Will laser resurfacing results last forever?

No. Resurfacing removes existing damage and stimulates new collagen, but skin continues to age and sun exposure continues to cause damage. The Mayo Clinic notes that lines and discoloration can return over time. Consistent sun protection extends the benefit and reduces the risk of new pigment problems, which is why clinicians treat your sun habits as part of deciding whether you are a good candidate.
