Caring for melanin-rich skin: what is different and what works

Key takeaways

• Melanin-rich skin has the same number of pigment cells but larger, more active pigment packages, which protects against sun damage and also makes dark marks and keloids more likely.
• Skin cancer is less common in people of colour but is often found late, so check palms, soles and nails as well as sun-exposed skin.
• A tinted sunscreen with iron oxides, or a newer clear chemical formula, gives protection without a white cast and blocks the visible light that darkens marks.
• Niacinamide, azelaic acid, ceramides, shea butter and low-strength AHAs are the most useful ingredients; harsh acids, neat essential oils and lightening creams are the most harmful.
• Dryness, razor bumps and hairline acne are common and manageable; persistent problems deserve a dermatologist who treats skin of colour.

Brown and Black skin is not a darker version of a default. It has its own structure, its own strengths and its own weak points, and most mainstream skin care advice was written without it in mind. This guide explains what is genuinely different, the mistakes that cause the most trouble, how to build a routine that respects melanin-rich skin, and which ingredients deserve a place in it.

What is different about melanin-rich skin

Every skin tone has roughly the same number of pigment cells. The difference is in the melanosomes, the packages of melanin they make: in darker skin these are larger, more numerous, spread out individually rather than clustered, and broken down more slowly, so more pigment sits in the upper layers. A review of the research concluded that higher melanin content and this different melanosome pattern are the best-supported differences, while most other claimed differences rest on small and often flawed studies¹.

That melanin is a genuine strength. It filters ultraviolet light, which is why skin cancer is less common in people of colour and visible sun ageing appears later¹. It is not immunity. When skin cancer does occur in darker skin it is often advanced by the time it is diagnosed, and it tends to appear in places that rarely see the sun: palms, soles, under nails, inside the mouth⁴.

The same active pigment cells are also the weak point. Any inflammation or injury, from a spot to a harsh scrub, can leave a dark mark that lasts months, and keloid scars are more common too; our guides on dark spots and acne scars cover both. Dryness is the other everyday issue. In one review, six of eight studies found more water loss through Black skin than white skin, and Black skin shed its surface cells about two and a half times faster, which may explain why dry skin is more often seen; many other measurements were inconsistent³. Another review notes that darker skin has been reported to have the lowest ceramide levels yet a strong barrier once challenged, and warns that most studies are small and individual differences often outweigh group ones². The grey, "ashy" look of dry skin is simply flaking that shows more against deeper skin⁶.

Conditions you are more likely to meet

Razor bumps (pseudofolliculitis barbae) happen when tightly curled hair, cut to a sharp point by shaving, curls back into the skin and sets off inflammation. Estimates suggest 45 to 80% of men of African ancestry are affected, and the complications are the familiar ones: dark marks and keloids⁷. Dermatosis papulosa nigra, the small, smooth, dark bumps that appear on the cheeks and neck from adolescence onward, is harmless and runs in families; removal is cosmetic and best left to a dermatologist, because rough treatment can leave light or dark patches. Hairline acne from oily hair products is covered below.

Sunscreen without the white cast

Evidence: strong. Daily sunscreen is the single most effective step against dark marks and melasma. Most of the skin-cancer evidence comes from studies in lighter skin.

The American Academy of Dermatology recommends broad-spectrum, water-resistant SPF 30 or higher for everyone, and specifically suggests a tinted sunscreen containing iron oxide for brown and Black skin⁴. The reason is visible light. Ordinary broad-spectrum sunscreens block ultraviolet but not visible light, which can cause pigmentation in darker skin, and to block it a sunscreen has to be visible on the skin. Zinc oxide and titanium dioxide in nanoparticle form go on clear but offer no visible-light protection; tinted sunscreens combine iron oxides with pigment-grade titanium dioxide to block it, and can be made in shades for every skin tone⁵.

That leaves three good options. A tinted mineral sunscreen matched to your skin gives the fullest protection. Newer chemical (organic) filters are formulated to go on clear and suit people who dislike any tint. And a thin layer of clear sunscreen with a tinted one over the top works well for deeper skin tones that find single-shade tints too light or too grey.

Ingredients that earn their place

Ceramides and a proper moisturiser

Evidence: moderate. Standard advice from the American Academy of Dermatology for dry, ashy skin⁶.

For very dry skin, the American Academy of Dermatology suggests a thick cream or an ointment rather than a lotion, with ceramides to reduce the grey look, applied within minutes of a short, warm, 5 to 10 minute shower while the skin is still damp, and reapplied through the day. Choose fragrance-free, and expect improvement in about two weeks⁶.

Niacinamide

Evidence: moderate. Strengthens the barrier and slows the transfer of pigment to the surface.

A 2 to 5% niacinamide serum or moisturiser does two useful things for melanin-rich skin: it reduces water loss and it reduces the pigment that reaches the surface after a spot. It rarely irritates. See niacinamide.

Azelaic acid

Evidence: moderate for dark marks; strong for acne at prescription strength. One of the few actives that treats spots and the marks they leave at the same time.

Around 10% over the counter, 15 to 20% on prescription. Because it calms inflammation while slowing pigment production, it is the closest thing to a single ingredient designed for skin that marks easily. Mild stinging in the first fortnight is normal. See azelaic acid.

Shea butter

Evidence: limited. A well-established emollient; claims beyond moisturising rest on laboratory work.

Shea butter seals moisture into the skin and has been used for generations across West Africa for exactly that. The American Academy of Dermatology notes that butters and oils tend to liquefy on the skin, which makes them less effective moisturisers than a cream or ointment on their own⁶; if you like shea butter, use it as a sealing layer over a ceramide cream or on damp skin rather than as your only moisturiser. It is heavy for acne-prone faces, so keep it for the body. See shea butter.

Gentle AHAs

Evidence: limited. Useful for rough texture, ash and razor bumps at low strength.

A 5 to 10% lactic or glycolic acid lotion two or three nights a week loosens the flaking that causes ash without the micro-tears of a scrub, and glycolic acid may reduce new razor bumps by exfoliating the follicle openings⁷. Lactic acid is the gentler choice. Always with morning sunscreen.

Ingredients to be careful with

High-strength acids and peels at home, neat essential oils, fragrance-heavy products and physical scrubs all cause the irritation that melanin-rich skin converts into marks. Hydroquinone belongs under a dermatologist's supervision only. And unregulated lightening creams are in a category of their own, covered below.

A simple routine for melanin-rich skin

1. Morning: gentle, fragrance-free cleanser; niacinamide serum; moisturiser; tinted or clear SPF 30 or higher.
2. Evening: cleanse; azelaic acid if you have spots or marks; moisturiser.
3. Two or three nights a week: a low-strength lactic acid lotion on the body or face in place of azelaic acid.
4. Body: 5 to 10 minute warm shower, pat until just damp, ceramide cream or a plain ointment straight away (shea butter, if you use it, goes on top as a sealing layer), and fragrance-free hand cream after every wash⁶.
5. Shaving: go with the direction of growth, do not stretch the skin, use short strokes with a sharp blade, leave about a millimetre of stubble, or switch to an electric shaver⁷.

Our simple natural skin care routine explains how to introduce products one at a time.

Common mistakes and what to avoid

• Skipping sunscreen because you do not burn. Marks and melasma do not need a burn to darken, and skin cancer is found late in people of colour⁴.
• Over-exfoliating. Scrubs, brushes and daily acids trade a day of smoothness for weeks of dark marks.
• Shaving too close. Close shaves and repeated passes drive hairs back under the skin; leaving light stubble or stopping shaving for a few weeks is the most reliable fix⁷.
• Oily hair products reaching the skin. Pomades, oils and heavy conditioners spread onto the forehead, hairline and back of the neck and clog pores. Switching to products labelled oil-free or non-comedogenic and washing pillowcases, hats and headbands helps, and for many people the spots settle over four to six weeks after the problem product is stopped⁸.
• Fragrance-heavy products on already dry skin. Deodorant soaps and products containing fragrance or alcohol can irritate skin that is already dry⁶.
• Lightening creams. A meta-analysis of 68 studies with 67,665 participants estimated that 27.7% had used skin bleaching products in their lifetime, with the highest rates in Africa, among people under 30, and among users of topical steroids⁹. Many such creams contain mercury or strong steroids. Treating a specific mark under guidance is one thing; lightening healthy skin is a different, and dangerous, project.

How long it takes

Dryness and ash should improve within about two weeks of consistent moisturising; if not, it may be eczema or another condition rather than simple dry skin⁶. Hairline acne often settles over four to six weeks for many people once the product is stopped, and if it has not improved by about six weeks, it is worth seeing a dermatologist⁸. Razor bumps settle over several weeks when shaving stops or changes⁷. Dark marks are the slow ones: months for mild marks, longer for deep ones, and daily sunscreen is what shortens the wait.

When to get professional help

Dermatologists who regularly treat skin of colour know which procedures and settings are safe for it. The American Academy of Dermatology's Find a Dermatologist tool can be filtered for a "Skin of Color" practice focus⁶, and the Skin of Color Society runs a directory of its members.

Our page on when to see a dermatologist covers what to bring and how to ask the right questions, and our free weekly skin care tips are written with melanin-rich skin in mind.

Common questions

Does Black skin really need sunscreen?

Yes. Melanin filters a good deal of ultraviolet light, which is why skin cancer is less common in people of colour, but it does not stop sun from darkening existing marks or triggering melasma, and skin cancer that does occur is often found late. A tinted mineral sunscreen with iron oxides, or a clear modern chemical filter, avoids the white cast that puts many people off.

Why does my skin look ashy, and how do I stop it?

Ash is ordinary flaking that shows up more against deeper skin, and studies suggest Black skin loses water and sheds surface cells faster than white skin. Short warm showers, a fragrance-free cream or ointment with ceramides applied to damp skin, and reapplying through the day usually bring some improvement within about two weeks. If it does not improve, it may be eczema or another condition rather than simple dryness.

Are skin-lightening creams dangerous?

Many are. Creams sold informally or online have repeatedly been found to contain mercury, which damages the nervous system and kidneys and can poison other people in the household, or strong steroids that thin the skin. A global analysis estimated that more than a quarter of people in the studied populations had used skin bleaching products, so this is a widespread problem rather than a rare one. Treating specific dark marks under professional guidance is a different thing from lightening healthy skin.

How do I find a dermatologist who understands darker skin?

The American Academy of Dermatology's Find a Dermatologist tool lets you filter by a 'Skin of Color' practice focus, and the Skin of Color Society runs its own directory. Ask any clinic how often they treat people with your skin tone before booking a procedure.
