Sunburn Preparations

Abstract

The beneficial effects of sunlight on the human organism are well known. Ultra-violet light in contact with the skin yields vitamin D which acts as a tonic and stimulant, incidentally assisting the body to ward off disease. Providing sun-bathing is not indulged in to excess, the epidermis is able to tolerate the mildest erythema without discomfort. Vivid erythema is produced after approximately one hour’s exposure of the skin to the sun on a cloudless summer day, and for normal untreated skins, this is about the maximum period, wisely indulged in. Beyond that painful burns result and excessive periods of exposure to the sun yield blisters.
