Lasers, peels and microneedling on deeper skin tones

Lasers, peels and microneedling can leave dark or light patches, or burns, on deeper skin. What changes the risk, and questions to ask a provider.

Education, not a diagnosis. Only a clinician who examines your skin can say what you have. Every point below shows how strong the evidence is and links to its source.

Who it affects

  • Anyone can have side effects from these procedures. With lasers and light devices, medium to deep skin is reported to face more dark marks, light patches, burns and scarring, including keloids, because pigment near the surface absorbs the energy.[1,2]Supported
  • Dermatology guidance notes that permanent lighter or darker patches are possible after peels and laser hair removal on darker skin.[2,3]Mechanistic only
  • People with melasma or a history of dark marks can see them get worse after procedures.[4,5,6]Supported
  • In a study of superficial peels at one expert center, side effects were uncommon and cleared up, but people with the deepest skin type had higher odds of one.[7]Thin

What it can look like

  • Side effects can include new dark marks, light patches, crusting, redness, blistering burns and scarring.[1,7,8]Supported
  • Intense pulsed light (IPL) on darker skin can occasionally cause unexpected extra hair growth in the treated area.[1]Thin

What helps

Who does it matters

  • The American Academy of Dermatology advises a board-certified dermatologist with experience treating darker skin for lasers and peels.[2,3]Mechanistic only
  • In one reported case, IPL given by an unqualified operator caused blistering burns on medium-brown skin, with dark marks still there months later. One case cannot show how often this happens.[8]Thin
  • Results from a single expert center may not match what happens in other settings.[7]Thin

What experienced clinicians do to lower the risk

These are clinician decisions. They are here so you know what to ask about.

  • Reviews describe longer laser wavelengths, conservative energy settings and longer pulses as ways to reduce risk on deeper skin.[1,9]Mechanistic only
  • A test spot before full treatment shows how your skin reacts before a larger area is treated.[1]Mechanistic only
  • Sun protection before and after is part of the plan for laser treatments and peels.[1,2,3]Mechanistic only
  • A clear talk about risks before treatment is part of good practice.[1]Mechanistic only

Chemical peels

  • Light peels heal in about a week. Medium and deep peels take one to three weeks and need more aftercare.[3]Mechanistic only
  • Superficial glycolic and salicylic acid peels showed low side-effect rates on darker skin in a few studies. A 2026 review found only 7 studies good enough to include, all small and short.[7,10]Thin
  • Burns from improper peel use have been reported.[10]Thin

Lasers for dark marks

  • For dark marks after inflammation, lasers are generally tried after creams and gels, because response varies, cost is high and complications are possible.[11]Mechanistic only
  • In a review of studies where most participants were Black, laser treatment on its own sometimes made marks worse.[12]Thin
  • Some laser types show promise for stubborn marks when settings suit the skin. That does not make any device right for a given person.[11]Thin
  • In a small split-face study on acne scars in medium to deep skin, a fractional CO2 laser improved scars more than microneedling but left dark marks more often.[13]Thin

Microneedling

  • Reviews suggest microneedling carries a lower risk of color change and scarring on deeper skin than traditional resurfacing.[14]Thin
  • In a review of radiofrequency microneedling on skin types III to VI, several studies still reported temporary dark marks, and one reported permanent scarring.[15]Thin

Procedures and melasma

  • For melasma, peels and lasers gave mixed results with more side effects than creams, and can make it worse, particularly in people of color.[4,5,16]Supported
  • Procedures are not a first step for melasma, and it tends to come back.[5,17]Supported

What to avoid

  • Booking with someone who can't tell you how often they treat skin like yours.[2,3,8]Mechanistic only
  • Skipping a test spot on deeper skin.[1]Mechanistic only
  • Unprotected sun exposure around the time of treatment.[2,3]Mechanistic only
  • Improper use of peels, which has led to burns.[10]Thin
  • Seeing a procedure as a quick fix for melasma.[4,5]Supported
  • Taking device marketing that says melanin-safe as a promise of low risk for you.[1,2]Mechanistic only
  • Picking at crusts or scabs while skin heals, which adds injury.[18,19]Mechanistic only

When to see a clinician

  • Blistering or a burn appears after a procedure.[8,10]Thin
  • New dark or light patches appear after treatment.[1,3]Supported
  • Melasma or dark marks get worse after a procedure.[5,6]Supported
  • Before booking, if melasma, dark marks or keloids are part of your skin history.[1,5,18]Mechanistic only

Questions to ask a provider

  • How often do you do this procedure on people with my skin tone?
  • Which device, wavelength, or peel type and depth do you plan to use, and why does it suit deeper skin?
  • Will you do a test spot first, and how long will we wait before checking it?
  • What is the chance of dark or light patches, burns or scarring for me, and what happens if they occur?
  • Should I avoid sun or change any skin-care products before or after, and for how long?
  • I have a history of melasma or dark marks. Could this procedure make it worse?
  • Is it worth trying a cream or gel first?

Label claims to question

“Melanin-safe or safe for dark skin”
May mean a device or clinic has experience with deeper skin. No regulatory definition was found, and procedures described this way still carry a higher risk of dark marks, light patches and burns on deeper skin.[1,2]
“For all skin tones”
Suggests broad use. It does not show the treatment was studied on medium to deep skin, or at the settings used on you.[1,20]
“Clinically proven”
Procedure studies on deeper skin are mostly small, short or from single expert centers. Ask which study, on which skin types, and with what follow-up.[4,7,10]

Where the evidence is thin

  • Safety evidence for procedures on deeper skin comes from small studies, single centers and expert reviews. No pooled complication rates were found for lasers.
  • No data were found on medium or deep peels in the deepest skin types.
  • Complication rates from expert centers may understate what happens elsewhere, as the case of burns from an unqualified operator suggests.
  • Cooling is described in one review as a way to lower laser risk, but a systematic review found cooling devices worsened dark marks in its studies. The sources do not settle this.
  • The evidence that microneedling is gentler on pigment comes from reviews that were not systematic and from small studies.

  9. [9]Postinflammatory hyperpigmentation: a review of the epidemiology, clinical features, and treatment options in skin of color · J Clin Aesthet Dermatol 3(7):20–31, 2010Establishes: PIH is more frequent and more severe in darker skin. Cites a 2002 acne study reporting PIH in 65.3% of African-American, 52.7% of Hispanic and 47.4% of Asian acne patients. Explains epidermal vs dermal PIH. First-line care is treating the underlying inflammation plus photoprotection and depigmenting agents; treatment irritation can worsen PIH. Agents covered: hydroquinone 2–4% (ochronosis risk with prolonged use), azelaic acid 20%, retinoids (irritation in up to about 50%), niacinamide, kojic acid (contact dermatitis common), vitamin C. Glycolic and salicylic peels need care. Longer laser wavelengths are described as lower-risk.Does not establish: Graded evidence — it is a narrative review, 16 years old.

Overall complications look uncommon.Does not establish: Much about treating hyperpigmentation — only one study addressed it as the target. Study quality was heterogeneous.
  16. [16]Melasma · Skin of Color Society, 2026Establishes: Melasma mostly affects women (90% is cited) and people of colour, with higher prevalence said to occur in Latin America, Asia, the Middle East and Northern Africa. Even small amounts of light can trigger it. Pregnancy melasma often fades after delivery. Peels, microdermabrasion and lasers give inconsistent results and may worsen it.Does not establish: Country-level prevalence data.
  17. [17]Melasma · DermNet (NZ), 2025Establishes: Melasma mainly affects women aged 20–40 with Fitzpatrick III–IV skin. Hormonal factors, UV and visible light, and family history are involved. Year-round SPF50+ sunscreen with iron oxides is advised. Relapse is common, and peels and lasers can worsen it.Does not establish: Population prevalence figures. The page's statement that melasma is less common in very dark skin is not sourced.
  18. [18]10 tips for clearing acne in darker skin tones · American Academy of Dermatology, 2026Establishes: Advises treating acne and dark spots together and early, to lower the chance of keloids and dark spots, and starting benzoyl peroxide at a low strength (2.5%) to limit irritation. Suggests swapping oil-based hair products for water- or glycerin-based ones if acne is on the forehead or temples ('pomade acne'), and using non-comedogenic products and gentle care. Says to avoid scrubbing and picking, and to see a dermatologist before peels, microdermabrasion or lasers, which can leave lasting light or dark spots in darker skin without expertise.Does not establish: How often these complications happen, or trial evidence for the tips. It does not address isotretinoin.

[19]Postinflammatory Hyperpigmentation (StatPearls) · NCBI Bookshelf (Lawrence, Syed, Al Aboud), 2024Establishes: PIH is more common in Fitzpatrick IV–VI; up to 65% in darker-skinned acne patients. Triggers include acne, dermatitis, infections, lasers, peels, cryotherapy and burns. Epidermal PIH resolves in about 6–12 months; dermal PIH is slow and may be permanent. Prevention: sunscreen, gentle care, not picking, treating inflammation early. Combination therapy is described as most effective.Does not establish: Systematic grading — it is not a systematic review. Does not discuss niacinamide or tranexamic acid.
  20. [20]Photoprotection for people with skin of colour: needs and strategies · Br J Dermatol 188(2):168–175, 2023 · read at abstract levelEstablishes: People with skin of colour remain vulnerable to UV-exacerbated pigmentary disorders and use photoprotection less often. Suitable sunscreens need good cosmetic acceptability (no white residue), high SPF, broad spectrum, UVA1 coverage and visible-light protection.Does not establish: Product performance — it tests none.
