In order to get a tan, one must have the skin pigment called melanin. Some blondes and redhead people have the skin pigment melanin in spots called freckles. Some have many freckles that run together, but the color is usually uneven.

People with skin type I, rarely tan. The body does not produce melanin or protective agents that help to prevent the destruction of your DNA in your body.

Regards Tanning Pills:
The tanning pills will not help your body to tan if you have any sort of skin type, but people with skin type I are most vulnerable, as the skin is already super sensitive. This may be dangerous as a person with such a skin type may be more vulnerable to sunburns.

If one doesn't have the skin pigment, then they can't tan, Simple as.

That is supposed to be taught in schools under Anatomy and Physiology. What are they teaching people now?

Those are the most susceptible to skin cancers and need a sunscreen to go out in the

No pigment. No tan. Sorry.

Best Sunless Tanning
The best sunless tanning results depend what an individual deems a great tan. The best sunless tanning that lasts only a couple of days is spray tanning. This results in an even glowing tan on the body without the risk of UV rays on sensitive skin or streaks and orange spots on the skin due to sunless tanning lotion.

It is said that the best sunless tanning that lasts the longest amount of time and doesn’t wash off is often the regular use of the tanning bed.

How Tanning Works

So, now that we know all about the skin we can start to actually understand tans and sunburns. When you get a tan, what is actually happening is that the melanocytes are producing melanin pigment in reaction to ultraviolet light in sunlight. Ultraviolet light stimulates melanin production. The pigment has the effect of absorbing the UV radiation in sunlight, so it protects the cells from UV damage. Melanin production takes a fair amount of time - that is why most people cannot get a tan in one day. You have to expose yourself to UV for a short period of time to activate the melanocytes. They produce melanin over the course of hours. By repeating this process over 5 to 7 days pigment builds up in your cells to a level that is protective.

The previous paragraph applies to Caucasians. In a variety of other races melanin production is continuous, so the skin is always pigmented to some degree. In these races the incidence of skin cancer is much lower because cells are constantly protected from UV radiation by melanin.

Melanocytes actually produce two different pigments: eumelanin (brown) and phaeomelanin (yellow and red). Red heads happen to produce more phaeomelanin and less eumelanin, which is why they don't tan very well. In albinos, the chemical pathway that produces melanin cannot proceed because an enzyme called Tyrosinase is missing. Therefore albinos have no melanin in their skin, hair or irises.

Melanocyte-stimulating hormone (MSH) is produced by the pituitary gland. MSH flows through the bloodstream and reaches the melanocytes, encouraging them to produce more melanin (for example, a person injected with a large dose of MSH will get darker). The pituitary gland is actually quite interesting - it is tied into the optic nerve, which means that it can sense light. If you have ever raised chickens for eggs, you know that in the winter egg production falls way off. You solve this problem by providing light in the chicken coop. The extra light stimulates the pituitary gland in chickens, which causes the gland to produce a hormone essential to egg laying. In humans, light affects the pituitary gland as well and one result is the production of MSH. A funny side-effect of all of this is that wearing sunglasses may make you more susceptible to sunburn!

How Sunlight Works

Sunlight arrives on earth in three forms: infrared (heat), visible light and ultraviolet. Ultraviolet light is classified into three categories:

• UVA (315 to 400 nm), also known as black light, which causes tanning
  
• UVB (280 to 315 nm), which causes damage in the form of sunburn
  
• UVC (100 to 280 nm), which is filtered out by the atmosphere and never reaches us.
  

99% of the sun's UV radiation at sea level is UVA. It is the UVB that causes most of the problems related to sun exposure: things like aging, wrinkles, cancer and so on, although research is increasingly implicating UVA as well.

One of the interesting things about UV radiation is that it is reflected by different surfaces. These reflections can amplify the effects of UV exposure. For example, snow reflects 90% of UV light. That is why you can get snow blindness and severe sunburns from skiing on a sunny day. Sand can reflect up to 20% of UVB that hits it, meaning that you can get extra UV exposure at the beach.

On the other hand, certain things absorb almost all UV radiation partially or completely. Glass is one of these substances - many glasses are very good absorbers of UV (which is why you may have heard that you cannot get sunburn in a greenhouse - just make sure it is glass and not plastic covering the greenhouse!). Most sunscreens use chemicals that have the same UV-absorbing properties.
