Genetic factors influencing sunburn and tanning 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.
Melanin Production: Tanning occurs when the skin produces more melanin in response to UV exposure. If your skin doesn't produce enough melanin, you may not tan effectively. Sun Exposure: Limited exposure to the sun can also affect your ability to tan.
The reason you don't tan is because you don't have enough melanin in your skin. Melanin is the tanning colour in our skin. When we go in the sun it is produced to protect our skin. The evolutionary advantage of white skin was that, when there was seldom any sun; skin started to produce less melanin.

Sorry, if you're pale white you'll stay that way. There are several varieties of skin color, categorized into 6 different types by the Fitzpatrick system. Type I always burns and never tans when exposed to the sun's UV rays or to a tanning bed.
Because vitiligo spots have no melanin, they can't tan. If the skin isn't protected with sunscreen, vitiligo patches may burn or scar.
Natural Sun Tanning
Fair skin can tan under the sun, but only with care. Start with short, consistent exposure, about 10-15 minutes a day during safer times like early morning or late afternoon.
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.
As the summer sun starts to heat up, people flock to the beach to work on their summer tan. For the longest time it was believed that people with fair skin and red hair were only capable of turning tomato red under sun.
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.
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.
To achieve best results, it is paramount that the DHA in the spray tan and the amino acids in the skin react to each other. Skincare products like moisturisers, deodorants and oily products often obstruct this process and the spray tan will not set properly.
In the end, no sunscreen can completely prevent tanning if exposing skin to the sun for extended periods. The myth persists that lower SPF sunscreens aid tanning while higher SPF prevents it. In reality, tanning depends more on sun exposure time, skin tone, and a sunscreen's UVA blocking capacity than the SPF alone.
Genetic factors influencing sunburn and tanning
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.
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.
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.
Eat the right food. 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.
The incidence of this change varies, and depends on the type of medication involved. Some of the most common drugs involved are NSAIDs, antimalarials, psychotropic drugs, Amiodarone, cytotoxic drugs, tetracyclines, and heavy metals such as silver and gold (which must be ingested, not just worn).
Either you aren't out long enough or your SPF is too high. If you wear SPF 50 and reapply every two hours you can sit out all day and get little to no tan. OR you can just be the type of person that doesn't tan well. Some people go out into the sun and they burn and then it peels and burns again.
Unless pale skin is accompanied by pale lips, tongue, palms of the hands, inside of the mouth, and lining of the eyes, it is probably not a serious condition and does not require treatment. General paleness affects the entire body. It is most easily seen on the face, lining of the eyes, inner mouth, and nails.
Melanin is the brown pigment that causes tanning. Melanin is the body's way of protecting skin from burning. Darker-skinned people tan more deeply than lighter-skinned people because their melanocytes produce more melanin.
