Quick answer
Yes, darker skin can sunburn. Melanin offers roughly low-SPF-level protection, so more UV is needed to burn — but the burn still happens and still causes DNA damage. In richly pigmented skin it often shows as heat, tightness, tenderness, itch or a grey/ashen or deeper darkening rather than obvious redness. Broad-spectrum SPF 30+ is recommended for all skin tones, and checking should focus on palms, soles, nails and mucous membranes.
What melanin actually does
Eumelanin absorbs and scatters UV and neutralises some free radicals, raising the dose required to produce visible injury. The commonly quoted equivalent is a modest single-digit SPF. That changes the timescale of a burn substantially, and changes nothing about whether cumulative UV damages skin. The safe sun exposure calculator adjusts estimated tolerance by Fitzpatrick type for exactly this reason.
How a burn presents without obvious redness
- Heat and tightness across the exposed area.
- Tenderness to touch, sometimes with itch.
- Grey, ashen, purple-toned or noticeably deeper pigmentation.
- Swelling, then peeling several days later.
- Blistering in severe cases — a second-degree burn regardless of skin tone.
Same red flags, same urgency
Skin cancer in skin of colour
Incidence is lower but survival is worse, largely because diagnosis comes later. Acral lentiginous melanoma — on palms, soles and under nails — makes up a much larger proportion of melanomas in Black and Asian patients, and these sites are not the ones people are taught to watch. Squamous cell carcinoma in skin of colour also arises more often in areas of chronic inflammation or scarring rather than purely sun-exposed skin.
| Area | What to look for |
|---|---|
| Soles and heels | New, enlarging or irregular dark patches |
| Palms and finger creases | Asymmetric pigment, changing outline |
| Nails | A single new or widening dark band, pigment spreading onto the nail fold |
| Between toes | Dark spots, non-healing sores |
| Mouth and genital area | New pigmented or ulcerated lesions |
| Scars and chronic wounds | Areas that thicken, ulcerate or fail to heal |
Protection that fits
- Broad-spectrum SPF 30+ daily on exposed skin; tinted mineral formulas avoid the white cast issue.
- Protection threshold is UV 3 and above for every skin tone.
- UV also drives hyperpigmentation and melasma, so daily sunscreen supports pigment goals as well as cancer prevention.
- Hats, shade and clothing remain the most reliable options.
Building a checking habit
Check monthly, include the soles and nails, and photograph anything new. For a specific spot, the free AI mole checker gives an educational screening in about 30 seconds, and the three-month monitoring routine makes gradual change visible instead of relying on memory.

Frequently Asked Questions
Yes. Melanin provides meaningful but partial protection — roughly the equivalent of a low SPF, not immunity. Deeply pigmented skin needs a larger UV dose to burn, but it still burns, and it still accumulates the DNA damage associated with skin cancer and photoageing.
Often not pink. Common signs are tightness, heat, tenderness or itch in the exposed area, a grey, ashen, purple or deeper-than-usual darkening, and later peeling. Because clinicians and patients both look for redness, burns in richly pigmented skin are frequently recognised late or dismissed.
Yes. Dermatology bodies recommend broad-spectrum SPF 30 or above for all skin tones. Beyond burn prevention, UV drives hyperpigmentation, melasma and uneven tone — the pigment concerns most commonly raised in skin of colour — and contributes to photoageing.
Yes. Incidence is lower than in fair skin, but outcomes are consistently worse because diagnosis happens later. Acral lentiginous melanoma — occurring on palms, soles and under nails — accounts for a much larger share of melanomas in Black and Asian patients and is often missed.
Palms, soles, between the toes, under fingernails and toenails, the nail folds, and mucous membranes including inside the mouth and the genital area. A new or widening dark streak in a nail, or a changing spot on a sole, should always be assessed by a clinician.
The World Health Organization protection threshold of UV 3 and above applies to everyone. Deeper skin tones tolerate a longer unprotected interval at the same UV index, but the threshold at which protection becomes worthwhile is the same.
Frequently. Post-inflammatory hyperpigmentation after a burn is more pronounced and longer-lasting in richly pigmented skin, sometimes persisting for many months. Avoiding further UV on the affected area is the most important step while it settles.
The treatment is the same: cooling, fluids, bland fragrance-free moisturiser, oral anti-inflammatory if suitable, no popping of blisters. The difference is recognition — because redness is less visible, use heat, tightness, tenderness and pigment change as your cues.
Many nail pigment bands in richly pigmented skin are benign and long-standing. Concerning features include a single band that is new, widening, darker than the others, more than about 3 mm wide, irregular in colour, or associated with pigment spreading onto the surrounding skin. Any of those needs clinical assessment.
It is useful but incomplete. ABCDE was developed largely from pigmented lesions in fair skin. In deeper skin tones, add attention to site — palms, soles, nails and mucous membranes — and to any lesion that ulcerates, bleeds or fails to heal.
