Sunscreens have become since more than 40 years the most popular means of protection against UV radiation (UVR) in Western countries. Organic and inorganic filters with different absorption spectrum exist. They filter or scatter UVR. Protection from UVB is quantified as a minimal erythema dose-based sun protection factor. UVA protection testing is less

Contact Dermatitis, 1987
The patients sensitized to sunscreen agents who attended our Contact Dermatitis Clinic between February 1985 to March 1987 have been reviewed. 15 (5%) of 280 patients tested with sunscreens had positive reactions: 3 of them were allergic to more than one agent. The most frequent contact allergens were hydroxy methoxy methyl benzophenone (Mexenone) [6].

British Journal of Dermatology, 1990
The most reliable way to reduce the chronic effects of solar UV radiation is to limit exposure. Animal data using hairless albino mice suggest that the routine use of sunscreens, which usually act as UVB (280-315 nm) filters, may prevent or inhibit skin photocarcinogenesis and photoageing in man.

ABSTRACT To the Editor:— Dr. Resnik's answer to the treatment for chloasma (208:159, 1969) did not state what type of sunscreen is to be used and why.The Meirowsky phenomenon he mentioned occurs one hour after sun exposure at wave lengths above 3,200 A and only darkens preformed melanin in all the epidermal cells.
