Patient discussion about Natural lighting.

Q. is it dangerouse to stay in the sun even if you don't get burned? how bad is it if you only get a little tan? does it matter what is your skin type in the first place? is only getting burned dangerouse, or being in the sun alltogether?

A. It depends on skin type.

White skins are more prone to freckles and sunburn, and even worse, skin cancer than those who have darker skins. Most skin cancer patients are white-skinned.

Melanin, responsible for darkening of our skin. It is more dominant on people with darker skin than whiter skin. If the skin has high melanin content, they are less prone to have skin cancer.

It is not the sun who directly causes our skin to darken but the melanin. Melanin multiplies when we are exposed to sun.

By the way, this info doesn't intend to terrify white-skinned people but to be aware of our skin. We must take care of our largest organ in our body because it serves as a protection our inner organs.

Q. what does a sun block cream do? and what are a UV rays?

A. It blocks out harmful Ultra violet rays from the skin as the previous entries have related; however it can also block your ability to produce vitamin D. If you live in a northerly area or one that receives limited sunlight, its recommended to get at least 15 minutes of sun a day (this is probably best done with minimal sunblock) and according to personnal sun sensitivity. Another thing to keep in mind is that sunblock works best if applied 20 minutes before sun exposure.
