Synopsis The photoprotective efficacy of some topical sunscreens was determined ex-vivo by spectrophotometric assay using an irradiation monochromator and a diffuse reflectance sphere.

The results are also expressed as the percentage of the radiation stopped by the products in each spectral range (UVB, short UVA and long UVA). All… CONTINUE READING
