Because vitiligo spots have no melanin, they can't tan. If the skin isn't protected with sunscreen, vitiligo patches may burn or scar. Getting a tan on the rest of your body will only highlight the white patches, especially if you have light skin.
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.
If the skin has been inflamed or is severely dry, the melanocytes (cells that give the skin its color) in that area do not react to UV light the same as they do in non-affected/dry skin areas.
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.
Yes, it is possible for individuals with very pale skin to have difficulty tanning. People with fair skin typically have less melanin, the pigment responsible for skin color and tanning. This can make them more prone to sunburn rather than tanning.
Because vitiligo spots have no melanin, they can't tan. If the skin isn't protected with sunscreen, vitiligo patches may burn or scar. Getting a tan on the rest of your body will only highlight the white patches, especially if you have light skin.
Therefore, what will determine whether a person can tan or simply turn red is both the amount of melanin produced by their skin cells and its quality. Or, the ratio between “good and bad” melanin.
Skin Type 1
You may be Type 1 if you have pale skin that always burns and never tans. You probably have light blue, gray or green eyes and your hair is naturally blonde or red.
As you progress in your tanning journey your skin becomes thicker. This means it is harder for UV light to penetrate your skin. That is typically when you will reach a point where your skin is not getting any darker.
When learning how to avoid sun tanning, remember to wear dark and bright-coloured clothes as these absorb more UV rays and restrict those harmful rays from penetrating your skin. While wearing sunglasses to prevent sun damage, you can also use a hat with a brim. This will protect your face from direct sun rays.
The activation and production of melanin is responsible for skin pigmentation and the dark colour on your skin. Compared to the rest of the body, skin on the legs does not produce the same amount of melanin, which results in legs getting less tan.
Vitamin D. In some studies, Melasma has been associated with low levels of vitamin D. Vitamin D is important for skin health as it helps regulate skin cell growth and immune function. Sun exposure is a major vitamin D source, and vitamin D deficiency may affect the skin's ability to control pigmentation.
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.
Difficult-to-tan areas (e.g. leg skin, palms) are those where the skin has fewer melanocytes than other areas of the body that get more sun exposure. What are melanocytes? They are cells that produce pigment, which is released during a tanning bed session, entering the epidermis.
Paleness may be the result of decreased blood supply to the skin. It can also be due to decreased number of red blood cells (anemia). Paleness of the skin is not the same as loss of pigment from the skin. Paleness is related to blood flow in the skin rather than deposit of melanin in the skin.
Light-skinned people have fewer melanocyte cells. Dark-skinned people have more melanocyte cells. An individual does not have the ability to increase the number of melanocyte cells contained in his or her skin.
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.
Individuals with fair skin have a low production of melanin, which increases their sensitivity to the sun's rays. This skin type is particularly prone to sunburn and often struggles to tan. However, it's not impossible for fair skin to achieve a slight 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.
Some people have a perfect tanning gene, while others may never get the tan they want no matter how hard they try. Whether your skin tans or burns after sun exposure depends on your level of melanin pigmentation (shown by how dark your skin is or can get).
Both conditions cause white or light patches of skin or hair. Piebaldism occurs when a portion of your skin doesn't have melanocytes, which are cells that produce pigment (melanin). You're born with piebaldism. Vitiligo occurs when your body has melanocytes, but they're destroyed.
Very few studies have shown that melanin production can be increased in the human body. One small clinical trial suggests that a prescription medication called nitisinone may help increase melanin in people with a rare disease that causes pale skin and hair and poor vision.
Everyone has a limit. Your body can only create a certain amount of Melanin at a time which means that your tanning will only go so dark within a day. It also means that if you exceed this time frame then you could put your skin at risk.
