A good sunscreen is the most important product you can use to protect your skin and to reduce the chance of skin cancer and to slow the aging changes of your skin. The most effective ingredient in sunscreens is zinc oxide. It physically blocks the sun's ultraviolet rays from penetrating your skin. Fortunately zinc oxide now comes in microscopic crystals so that you don't have to look like the lifeguards of the past with thick white paste on their noses and lips. The other sunscreen ingredients work by absorbing the ultraviolet light and are not as effective.

If there is only one product that I would recommend that you use a good zinc oxide sunscreen is the one. Your skin will thank you for it for years to come.
