LipsSometimes we’re all forget that lip is one part of the body that need protection again UV radiation. Lip will not tan because there is no melanin present there. But remember, lip can burn too! As mucous membrane lips need to be protected from dehydration as well as from UV. The formulation that will work best on the lips is the anhydrous type, since these types are not easily washed off by saliva and moisture.

This formula is a typical SPF lip protectant.

The use of dimethicone as a skin protectant also makes this product a drug that must follow the FDA’s skin protectant monograpgh. Inorganic sunscreen are typically not used since a minimal SPF of 15 is sufficient and inorganics at high concentration, above 3%, will show a white residue.
