Although sunscreens are widely available and in common use, surveys show that an average of only half of the people on a beach on a given day wear sunscreens. Many people go to the beach to get or maintain a suntan, but many people also leave their skin unprotected.

Lignin: a nature-inspired sun blocker for broad-spectrum sunscreens
, 2015We report the evaluation of lignin for the development of high-performance broad-spectrum sunscreens. Lignin is added into several commercial sunscreen products. Significant enhancements in ultraviolet (UV) absorbance are observed.

The awareness of sun‐induced skin damage has increased in both the lay public and physician.Coincidentally, there has been progress in the development of new ultraviolet‐(UV) radiation protecting sunscreens. In this review and update on sunscreens, sunscreen classification, UVB and UVA protection, sunscreen vehicle, and substantivity will be addressed.

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.

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.

Contact sensitization to sunscreens
American Journal of Contact Dermatitis, 1997Para aminobenzoic acid (PABA) derivatives and cinnamate are chemical sunscreens that protect against UVB (290 to 320 nm). They may occasionally produce contact and photocontact sensitization.To report a sensitization to octyl-dimethyl-PABA and photosensitization to 2-ethylhexyl-p-metossicinnamate in a 31-year-old man.A patient with a 3-year history of ...
