Light skin provides better absorption qualities of ultraviolet radiation, which helps the body to synthesize higher amounts of vitamin D for bodily processes such as calcium development.
Lighter skin tones have less melanocytes, so UV rays penetrate the skin more easily, causing the skin to tan and burn quickly. With darker skin tones, the higher amounts of melanin block some of those UV rays, making it harder to tan or burn.
In a climate with less sunlight, lighter skin allows more sunlight in, as in it's TRYING to eat more because it HAS TO. Dark-skinned will be blocking more, so it's basically starving of Vitamin D. It's basically like avoiding eating various foods because you don't need that much of it, but you still have to eat SOME.
In light skin, the ultraviolet radiation penetrates more into the skin, developing a better absorption of ultraviolet radiation. Their body synthesizes a higher amount of vitamin d, and they help in calcium development. They have less chance of developing rickets in their body.
People with lighter or more pale skin have less melanin. They are more likely to burn from UV rays rather than tan. How quickly a person's skin can redden when exposed to UV rays can vary, but usually, the fairer or lighter the skin, the quicker it will burn.
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.
Dark tone is at the other end of the spectrum and is characterised by its rich, deep appearance due to higher amounts of melanin. People with darker skin tones rarely burn but tan very easily when exposed to more prolonged sun exposure.
Light skin is most commonly found amongst the native populations of Europe, East Asia, West Asia, Central Asia, Siberia, and North Africa as measured through skin reflectance.
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.
In some cultures, lighter skin has been associated with privilege, power, and social status, creating a bias towards individuals with paler complexions. This bias is deeply rooted in historical constructs of colonialism, where lighter-skinned individuals were often viewed as superior or more desirable.
Research shows that spending time in the sun can increase your vitamin D levels, reduce your risk of certain health conditions, and improve your overall well-being. Experts recommend getting 10 to 30 minutes of sunlight most days of the week.
Circulating vitamin D concentrations differ by skin color: Individuals with darker skin produce less vitamin D with the same amount of sunlight exposure than individuals with lighter skin color [10,12].
Vitamin D synthesis is highly dependent on the concentration of melanin in the skin as melanin absorbs and scatters UVR-B, resulting in a less efficient conversion of 7-dehydrocholesterol to previtamin D3[3]. Therefore, dark-skinned individuals will experience slower vitamin D synthesis than light-skinned ones.
“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.
It was found that on the average, five times as much ultraviolet light (UVB and UVA) reaches the upper dermis of Caucasians as reaches that of blacks. Differences in transmission between the stratum corneum of blacks and of Caucasians were far less striking.
The preference for more golden or 'yellow-toned' skin as healthier might be explained by the 'carotenoid pigments' that we get from the fruit and vegetables in our diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when the body combats disease.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Natalie Portman is known for her perfectly clear and radiant complexion, her skin seems to glow so naturally. The star insists on the importance of drinking a lot of water every day to keep the skin moisturized and fresh.
Americans of Asian descent are the least likely to be obese, and those of Latino descent the most likely, new data indicates.
Diet plays a large role in keeping skin beautiful and fresh. Japan, China and other countries located in Asia have a rich diet of vitamins (specifically A and C, which benefit skin elasticity) and minerals including antioxidants from fruits and green tea. The Asian diet is very low in saturated and total fat.
Golden skin tones are medium skin tones. This skin tone is usually seen in people of Asian and Southern European ethnic descent. It can also be referred to as olive skin. This skin tone has a balanced neutral beige hue.
Look into a mirror in natural light. Artificial lighting can alter the appearance of your natural skin colour. Notice the colour of the skin along your jawline or behind your ear. These areas typically tend to show your skin tone in its purest form, without any redness or discolouration that could get in the way.
There's science behind our logic: almost all blues will make a tan look darker, but it's the shadeson the blue-green/turquoise spectrum that have maximum impact. Of course, knitwear isn't ideal for showing off your tan, but the flex lies in teaming your sweater or jacket with short shorts.
Fruit and veg that's high in beta carotene, which can help you tan, but without burning. Beta-carotene is widely recognised as being an excellent antioxidant that fights free radicals and reduces skin damage and oxidative stress on the skin, helping limit the harmful effects of UV light.
