Melanin helps block out damaging UV rays up to a point, which is why people with naturally darker skin are less likely to get sunburned, while people with lighter skin are more likely to burn. Sunburns can increase your risk of skin cancer, including melanoma.
What you need to know about sunburn. Some people are more prone to sunburn: Skin type determines your susceptibility; people with fair skin run the greatest risk. But anyone can get burned. Even without a burn, sun exposure raises skin cancer risk.
The short and long answer—yes. Yup, it's true that Black and dark-skinned people are less sensitive to the sun, but that doesn't mean that you can't get a sunburn, skin damage, hyperpigmentation, or even skin cancer.
Since the amount of melanin you can produce is determined by genetics, some people are more prone to burn, while others tan. Although any skin tone can burn, people with naturally darker skin are less likely to do so.

All types of sunburn, whether serious or mild, can cause permanent and irreversible skin damage. This could lay the groundwork for skin cancers to develop. Further sunburn only increases your risk of skin cancer.
The thick layer of dead skin that covers the undersides of feet and hands reduces the amount of UV light that penetrates to the living layers beneath. Rays that make it through find fewer melanocytes to stimulate.
You may have noticed that sunburns can later turn into a tan. And this is true – but it's not a good sign.
Americans with darker complexions still face a real risk from the sun, many dermatologists say, including a higher risk of death if they do get melanoma. Those same experts stress everyone should wear sunscreen to protect against forms of skin cancer and other harmful effects. “The risk is less.
Nearly 1 of 10 Native Americans (NAs) believe that Native peoples do not develop skin cancer, and nearly 9 of 10 have been sunburned at least once.
Darker-skinned people considered safe up to two hours. Low: Index of 3-4; fair people can spend 15 minutes in the sun. Others face damage after 75 to 90 minutes. Moderate: Index of 5-6; fair-skinned people shouldn't stay outside without protection for more than 10 minutes.
Black skin, compared with white skin, is generally assumed to be more resistant to the consequences of sun exposure due to its epidermal melanin content. However, recent scientific evidence shows that black skin is not completely impervious to sunlight.
Strictly avoiding outdoor exposure can also have a negative effect on your general wellbeing and quality of life. How do I desensitise with natural sunlight? You can try to build up your skin's resistance to sunlight by going outside for short periods, and gradually building up the time you spend outdoors.
Avoid putting ice on a sunburn, as this can make matters worse by causing intense vasoconstriction, where blood vessels narrow sharply and cut off local blood supply to already damaged skin. Moisturising lotions can also help soothe by keeping moisture in, but avoid skin-numbing creams unless prescribed by your doctor.
Do you wear sunscreen, but still get sunburned? You might be using it incorrectly. “The biggest thing I see with patients is that they are not applying enough sunscreen and they aren't reapplying it,” says David Harvey, M.D., a dermatologist and Mohs surgeon at Piedmont.
To help with pain relief, it is recommended to apply aloe lotion or gel, place a cool cloth on the area and take an over-the-counter pain reliever. Unlike the other degrees of sunburn, third-degree burns are noticeably less painful or even painless.
How long a sunburn lasts depends on how severe the burn is, Connecticut-based dermatologist Rhonda Q. Klein, MD, told Health. "Most sunburns will lose their associated pain and red tone in three to five days. But if you have a more severe, blistering burn, this could last up to 10 days," Dr.
Redness (sunburn) often is not seen until 4 hours after being in the sun. The pain and redness keep getting worse. They don't peak for 24 to 36 hours.
And it's because of melanin that some scientists believe darker skin tones absorb between 50 to 70 percent less of the sun's ultraviolet light than paler skin tones. Exactly how much less is not well understood because fewer studies look at how darker skin reacts to the sun.
The skin on your legs is thick so it's harder for the sun's rays to penetrate it. Also, if you're finding it difficult to tan your legs, then your legs may not produce as much melanin as the rest of your body, so it may be difficult to ever get them as dark as other parts of your body.
While your hair may protect most of your scalp from harmful ultraviolet (UV) light, there are parts of it that remain unprotected, namely the hairline and part line. Also, those dealing with hair loss are even more vulnerable to the dangers of scalp sunburn.
Signs of photodamage begin in the teens to early twenties. Symptoms include the following: Wrinkling. Pigmentation changes such as age spots, liver spots (solar lentigines) and freckles.
Key Takeaways. Getting sunburned five times can more than double your risk of developing skin cancer, but any sun damage at all can contribute to the potential for long-term effects. A full-body burn is going to cause more damage than a small-area burn.
You may ask "what harm can one sunburn do?" Answer: A lot. Even a single sunburn can increase your risk for developing skin cancer. It's not the burn itself that affects your risk; it's the amount of sun exposure that's associated with that burn.
