Melanin helps block out damaging UV rays up to a point, which is why people with naturally darker skin are less likely to get a sunburn. People with lighter or more pale skin have less melanin. They are more likely to burn from UV rays rather than tan.
The pigment melanin is what makes people tan. When your skin is naturally more pigmented(darker), it means that you have more melanin than people who have lighter skin. The more melanin a person has in their natural skin, the easier it is for them to get a tan and not burn.
More melanin. Melanin is what gives our skin, hair, and eyes color. Mixed people who don't get sunburnt tend to have more melanin. People with lighter skin have less melanin to protect them from the sun. As such the suns rays penetrate deeper in t...
Yes. Unfortunately, darker skins may absorb more infrared (IR) radiation and this can increase the heat responses in the skin. New scientific research shows one third of infrared radiation can penetrate the deepest layers of the skin and may increase the risk of pigmentation and even cancer.

While dark skin is better protected from ultraviolet radiation, it does absorb more of the energy in visible light than light skin. But most of the sun's heat comes in invisible infrared radiation. Dark and light skin are the same color in that range. Dark skin absorbs no more heat than light skin does.
Type IV – Brown skin color, brown hair, and brown eyes, tans more than average, rarely burns, and rarely freckles. Common ethnic background: the Mediterranean, Southern European, Hispanic.
For the longest time it was believed that people with fair skin and red hair were only capable of turning tomato red under sun. According to ScienceDaily, however, there is a new study that shows fairer complexions are just as capable of tanning as their olive counterparts.
Your Sunscreen Doesn't Have Enough UVA Protection
However, it's the UVA rays that cause tanning. In North America, look for the words “Broad Spectrum” as an indication that the sun filters used in the formulation protect from both UVB and UVA rays.
“Work in our lab has shown that darkly pigmented skin has far better function, including a better barrier to water loss, stronger cohesion, and better antimicrobial defense, and we began to ponder the possible evolutionary significance of that,” said Peter Elias, MD, professor of dermatology.
Genetics play a significant role in how our skin responds to sun exposure. Certain genes influence melanin production and skin color, affecting whether you tan or burn. People with fair skin have less melanin and are more prone to burning, while those with darker skin have more melanin and are more likely to tan.
Cool the skin for about 10 minutes several times a day. Apply a moisturizer, lotion or gel. An aloe vera lotion or gel or calamine lotion can be soothing. Try cooling the product in the refrigerator before applying.
Today, having a tan is associated with people that have an active, outdoor lifestyle. A tan therefore makes people look healthier and fit. Pale skin is often associated with sickness (e.g. anaemia) which is another, indirect reason why a tan makes people seem healthier.
It's true, darker skin ages slower than lighter skin. You could even say that the darker the skin color, the slower it ages.
This happens because “Each of us produces a different quantity and quality of melanin. Melanin is a pigment produced by our cells found in the basal layer of the skin,” explains Dr Puig.
According to a study called “Shades of beauty,” light brown skin tones are often the most physically attractive skin color (Frisby et al., 2006). They used four models for that study. They did not change the skin tone, but they imaged each model to three different skin tones: light, medium, and dark.
The most prevalent fatty acid in sebum, sapienic acid (16:1, n10), is significantly higher in African Americans and correlated with the higher sebum output in that ethnic group.
It is frequent among select indigenous populations of Latin America, parts of Sub-Saharan Africa, and South Asia. It ranges from olive to brown skin tones. This skin type very rarely burns and tans quite easily.
Collagen fibers are more numerous and denser, and elastic fibers are mostly undegraded elastic fibers. Thanks to its characteristics they persist longer. Therefore dark skin is naturally firmer and more resistant in the long term which delays the appearance of wrinkles at the age of 50 or 60 years.
Again, on day 6, 25-(OH)-D levels of fair-skinned volunteers increased significantly (median: 11.9-14.3 ng/ml, p < 0.0001), but not in black-skinned people (median: 8.60-9.57 ng/ml, p = 0.375). Conclusion: This study suggests that skin pigmentation negatively influences vitamin D synthesis.
Lighter- skin was perceived as being more attractive, and associated with four themes about dating: (a) positive personality traits, (b) increased value in dating contexts, and (c) sexual appeal to men.
