Exactly, the chance that you get skin cancer looks like a U-shaped graph when plotted against the amount of time spent in the sun. People who get very little or no sun exposure at all have moderately high rates of skin cancer. People who get 5-10 minutes of sun every few days have a very low rate of skin cancer. People who get 15+ minutes of sun a day have very high rates of skin cancer. Thus putting on too much sunscreen is the same as staying indoors - you don't get your vitamin D, you don't get protective tans, and you get more skin cancer. Sunscreen doesn't cause cancer, complete lack of sun causes cancer. So if you are the type of person who rarely gets outside, don't wear sunscreen. But if you are the type of person who is outside a lot, wear sunscreen.Originally posted by: Amused
There is also evidence that blocking all exposure to UVB creates deficiencies in vitamin D, which can lead to problems.
Everything in moderation when it comes to health.
What about seasonal expose? How does it apply to people who get tanned or even burned in the summer but not so much in the winter?
That means you have to moderate your summer exposure better.
