Definitions for "Sunscreens"
Keywords:  spf, parsol, sunburn, lotions, label
All sun-protection products labeled with an SPF of 2 or higher are considered sunscreens. Sunscreen agents either absorb, reflect or scatter UV light. Most lotions and oils work by forming a surface layer of sunscreening ingredients on the skin, which absorb the sun's UV rays before they can penetrate the skin.
These come in two forms. Chemical sunscreens (such as Parsol 1789) absorb solar UV and distribute it as heat; physical sunscreens (such as micronized zinc oxide and titanium dioxide) reflect the solar UV.
Products strictly regulated by the FDA that provide protection from sunburn and some amount of sun damage. To find out the protection, consumers turn to a simple number: the SPF, or sun protection factor, listed on the label-the higher the number, the more the product protects the skin. Sunscreen should not be used to prolong time spent in the sun. Even with a sunscreen, you are not going to prevent all the possible damage from the sun.
