Scar and Pigment Treatment for Darker Skin: What to Know First

Why darker skin needs its own plan

Maybe a pimple left a dark mark that lasted longer than the pimple did. Maybe a small cut turned into a raised scar, or someone told you lasers are not for skin like yours. If you have medium to dark skin, it makes sense to ask how scar and pigment treatment works for you before you book anything.

Darker skin is not off limits. A StatPearls review on laser treatment of pigmented lesions, hosted by the NIH, says people with deeply pigmented skin, including Fitzpatrick type VI, can still receive laser treatments, but special care is needed. The reason is melanin, the pigment that gives skin its color. It absorbs laser light across a wide range of wavelengths, so in darker skin it competes with whatever the laser is aimed at.

The AAD puts the result plainly: lasers can be used on all skin types, but darker skin is more prone to burns and dark marks after laser treatment. Your Fitzpatrick skin type is one of the first things a provider should assess. If your question is about a tattoo rather than a scar or spot, the tattoo removal for skin of color guide covers that side.

Four skin problems that are more common in darker skin

Official sources point to a few conditions that show up more often, or more visibly, in medium to dark skin. Knowing which one you have shapes the whole plan.

• Keloids. The AAD says keloids are more common in Black and Latin American people in the United States, and that Black people between ages 10 and 30 have the greatest risk. About one-third of people with keloids have a close relative who gets them. The guide keloid vs. hypertrophic scar explains how to tell raised scars apart.
• Dark marks after inflammation. The AAD says dark spots and patches are one of the most common reasons people with darker skin see a dermatologist, and it names post-inflammatory hyperpigmentation as one cause. A StatPearls review says this condition is more common and more severe in darker skin. Acne, psoriasis, bites, cuts, burns and irritating skin products can all trigger it.
• Melasma. The AAD says melasma develops more often in medium and dark skin tones, especially in women of Latin, Asian, Black or Native American heritage. It can look tan, brown, grayish brown or bluish gray.
• Lighter patches. A 2023 medical review describes lighter skin after inflammation, called post-inflammatory hypopigmentation, as more noticeable in skin of color.

How careful providers lower the risk

The same StatPearls review explains that melanin absorbs less laser energy as the wavelength gets longer, so longer wavelengths should be used whenever possible on darker skin. It also says it is critical to test a small area of skin before treating the whole area, whatever your skin color. A test area shows how your skin reacts before a larger patch is at stake.

Pigment treatments need extra care. A StatPearls review on post-inflammatory hyperpigmentation says several laser types, including picosecond lasers, have been used to treat dark marks, but that they should be used cautiously because they can cause irritation and more hyperpigmentation. For melasma, the AAD notes that some treatments can irritate darker skin and make melasma darker, and that results often take longer in darker skin.

Laser Eraser's site says its providers can build in test spots when caution is warranted, and its melasma treatment page describes conservative settings, often starting with a small test area. If you have melasma, sun spots or dark marks and are not sure which, the guide melasma vs. sun spots vs. PIH explains how they differ.

Steps that protect your skin before any treatment

Much of what lowers your risk happens before the first appointment. These steps come from AAD guidance:

• Get active skin conditions under control. The AAD says that to clear dark marks caused by acne, eczema or psoriasis, the condition has to be treated first, or new marks keep forming.
• Protect your skin from the sun every day. The AAD recommends a tinted sunscreen with iron oxide, which helps block visible light, another cause of dark spots. Avoid tanning before laser treatment.
• Use gentle products. Products that burn or sting can irritate the skin and lead to new dark spots, according to the AAD.
• List your medicines and skin products. The AAD notes that some medicines make skin more sensitive to laser light, and you may need to pause products such as topical retinoids.
• Skip unlabeled skin lighteners. The AAD reports that some imported products contained steroids or mercury that were not listed on the label.

Questions worth asking at a consultation

A good consultation should leave you knowing what the provider thinks your scar or spot is and how they will protect your skin. Asking about skin type is not rude. It is part of safe care. These questions help:

• What do you think this is: a keloid, a raised scar, dark marks, melasma or something else?
• How often do you treat skin with a tone like mine?
• Will you test a small area first, and how long will we wait to judge it?
• What could go wrong for my skin type, such as darker or lighter patches, and what is the plan if it happens?
• Should I start with sunscreen or creams before any laser?

When another doctor should go first

Some situations call for a different first stop. A new, changing, bleeding, itching or irregular spot needs a dermatologist's exam before any laser, and the guide get a spot checked before laser explains why. Active acne usually needs medical treatment before scar or mark treatment makes sense.

If a raised scar is a keloid, Laser Eraser treats it with injections into the scar rather than laser, as the keloid scar page explains. For other scars and pigment, a licensed medical provider at a free consultation looks at your skin, considers your skin type and explains which of the practice's scar and pigment treatments might fit, or whether waiting makes more sense.
