Do Black people need sunscreen? How to pick one

Yes, darker skin needs sunscreen too. Melanin gives real protection, but not enough to skip it, and treatment for dark marks begins with sunscreen [5]. Marks a few shades darker than your skin usually fade within 6 to 12 months; deeper ones can take longer. Daily sunscreen keeps the sun from undoing that progress [5].

What melanin does and doesn't do

Melanin is natural protection. In a 1979 lab comparison of skin samples, about five times as much UV light reached the upper dermis (the layer under the surface) of white skin as of Black skin [2]. Skin cancer is also less common in darker skin [3].

Lower is not none. The AAD says you can get skin cancer with a darker skin tone, and that it is often advanced by the time it is found, which makes it harder to treat. It can appear where the sun rarely reaches, such as palms, soles, fingers, toes and nails [1]. One review adds that in dark-skinned groups, UV light is not an important cause of skin cancer, apart from one type (basal cell carcinoma) [3]. So sunscreen is not your whole skin-cancer plan. Checking your skin matters too.

Dermatologists still recommend sunscreen for everyone [1]. The NHS says that even with brown or Black skin, you should avoid burning and take care in the sun [13].

A note for UK readers

The British Association of Dermatologists takes a different line on skin cancer. It says that for people with black or dark brown skin, "routine sun protection is rarely necessary in the UK" [4]. It lists exceptions: skin conditions such as vitiligo, lupus or sun sensitivity, and a high risk of skin cancer. It adds that in places with stronger sun, you may need its standard sun advice [4].

That advice is about skin cancer in the UK climate. It is not about dark marks, which is the main reason for this guide.

Why sunscreen makes dark-mark treatment work

The AAD puts it plainly: effective treatment for dark spots and patches begins with sunscreen [5]. For post-inflammatory marks (the dark spots left after acne, bumps or irritation), the usual first approach is a fading ingredient plus daily sun protection [9].

It is not only UV light. In a study of 20 volunteers with darker skin (types IV to VI on the scale dermatologists use, which runs from I, palest, to VI, deepest), visible light, the light we see, caused pigment that was darker and lasted longer than the pigment from long-wave UVA. It caused none in the paler type II [6]. The AAD says visible light can increase darkening, particularly in darker skin tones [10].

Ordinary broad-spectrum sunscreens guard against UV but do not fully protect against visible light. To block visible light, a product has to be visible on the skin. That is what a tint does: iron oxides, a pigment, colour the sunscreen and help block visible light [7]. The AAD recommends a tinted sunscreen with iron oxide for dark spots [5].

How strong is the evidence? In one trial, 68 people with melasma (patches of darker skin on sun-exposed areas) were split into two groups; 61 finished. Everyone used the same prescribed fading cream for 8 weeks. The group with a tinted iron oxide sunscreen improved 15% more on a severity score, and 28% more on a skin-colour reading, than the group with a UV-only one [8]. It is a small study of one condition, so treat it as a good sign, not a promise.

One plain line: sunscreen does not change your natural colour, and no routine does. What it does is keep the sun from adding dark marks and uneven patches while your treatment works.

How to pick one

Check the label for four things.

• SPF 30 or higher. The AAD recommends it [12]. The NHS asks for SPF 30 plus at least four stars, the UK rating for UVA protection [13].
• Broad spectrum. Protection from both UVA (the rays that age skin) and UVB (the burning rays) [12].
• Water resistant if you sweat or swim. It holds for 40 or 80 minutes in water [12].
• Tinted, with iron oxide in the ingredient list. It is listed under inactive ingredients [5].

Mineral or chemical? Mineral sunscreens use zinc oxide, titanium dioxide, or both. Chemical ones contain neither. Hybrids mix the two [12]. White cast is the chalky look minerals can leave. Makers shrink these particles to cut the chalk, but the smaller particles do not protect against visible light [7]. So an untinted sunscreen of either type leaves a gap, and a tinted one matched to your tone avoids both problems [7][11]. Test the shade on your jawline in daylight. The best sunscreen is the one you will wear every day.

Oily skin and humid heat. For skin that breaks out or feels greasy, look for "non-comedogenic" or "won't clog pores" [11]. Choose water resistant if sweat is part of your day [11].

Irritated or stinging skin. Skip fragrance. If sunscreen stings or burns, the AAD suggests one with only zinc oxide and titanium dioxide [11]. In the US, "sensitive skin" on a label has no official definition, so read the ingredients [12].

How much and how often

• Amount. The NHS suggests 6 to 8 teaspoons for a whole adult body [13]. The AAD says about 1 ounce (a shot glass) for most adults, and at least 1 teaspoon for the face [14]. Most people use only 25 to 50% of the recommended amount [15].
• Timing. Put it on about 15 minutes before going out [14].
• Reapplying. Every two hours outdoors, and straight after swimming, sweating or towel-drying, even if the label says water resistant [13][14].
• Cloudy days. Up to 80% of UV can pass through clouds [10]. The WHO says UV is higher closer to the equator, which includes Nigeria, and that protection is advised when the UV index reaches 3 or above [16].
• Not alone. Shade and clothing help, because no sunscreen blocks 100% of UV [15]. Check expiry dates too [13].

Myths worth dropping

"Dark skin doesn't burn, so I don't need it." Melanin lowers risk but doesn't remove it [1][2], and both visible light and UV can deepen marks [6][10].

"My makeup has SPF, so I'm covered." The AAD notes that some cosmetics and moisturisers have SPF, but still advises reapplying sunscreen about every two hours outdoors [10]. In a study of 84 people, SPF 30 moisturiser left more of the face uncovered than sunscreen, mostly around the eyelids [17]. That study looked at moisturiser, not foundation. The NHS notes that a thin layer gives less protection [13].

"Sunscreen blocks vitamin D." The British Association of Dermatologists says a study found sunscreen does not stop most people making vitamin D. More research is needed on SPF 30 and above, and on people with dark skin, who have a higher risk of low vitamin D [18]. If you avoid the sun, ask a clinician about checking your vitamin D level [4].

Pregnancy and breastfeeding

Pregnancy raises the chance of dark patches such as melasma [19]. A 2025 review says sunscreens in pregnancy should ideally be mineral-based, and that tinted ones may help prevent those patches. It calls tinted mineral sunscreens with iron oxides generally safe in pregnancy and breastfeeding [19]. If you are unsure about a product, ask your midwife, doctor or pharmacist.

When to see a professional

• A mole, freckle or patch that has changed in size, shape or colour [13].
• A new dark line or streak in a nail, or a new spot on a palm or sole [1].
• Stinging, severe burning, a spreading rash, swelling or anything near the eyes after using a sunscreen.
• Skin that has become thin, red or bruises easily, for example after long use of a strong cream. Stopping a strong steroid cream is best done with a professional's help.
• Dark patches that keep spreading, or marks that haven't faded despite steady daily use and treatment [5].
