Abstract
The effect of applied thickness of sunscreen on the degree of protection against ultraviolet exposure has been investigated using an in vitro model (excised human epidermis) and phototesting in human subjects. The agreement between the protection factors obtained by each technique was excellent. It is shown that the influence of applied thickness on sunscreen protection factors is much less than would be predicted by Beer's law.This publication has 12 references indexed in Scilit:
