American Journal of Clinical Dermatology, 2001
Ultraviolet (UV) radiation is an etiologic factor for the development of nonmelanoma skin cancers and also possibly melanoma. The American Academy of Dermatology currently recommends the daily use of sunscreens with a sun protection factor (SPF) of 15 or above. The SPF numerical rating is an in vivo, standardized measure of sunscreen efficacy.

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

Part of the controversy surrounding sunscreens deals with issues of compliance. Sunscreens do not work if they remain in the bottle. It is estimated that the average United States adult uses less than one bottle of sunscreen per year. Clearly, this is indicative of poor compliance, since one bottle, if applied as directed on a daily basis, should last ...

The Medical Letter on Drugs and Therapeutics
Excessive exposure to ultraviolet (UV) radiation can cause erythema, photoaging, and skin cancer.1,2 Sunscreens are widely used to reduce these risks, but questions remain about their effectiveness and safety. In 2021, the FDA proposed a rule that would require additional safety studies for some sunscreen active ingredients and mandate better UVA ...

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].

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.
