The aim of this work was to compare the skin penetration of 4-methylbenzylidene-camphor (4-MBC) in two vehicles, an oil-in-water (O/W) emulsion and an alcoholic gel. The penetration of this UVB filter through these vehicles was determined in vitro (Franz cells) using pig ear skin. The 4-MBC permeated through the skin both with the emulsion o/w as the alcoholic gel. However, with the alcoholic gel, 5 h after application of the product, the 4-MBC was found in the receptor fluid, while with the emulsion o/w, 24 h after it was detected. In both vehicles, the 4-MBC was present in the viable epidermis, dermis but most part of it, was found in the stratum corneum, being more remarkable for alcoholic gel. The right choice of the vehicle could decrease the... |

The aim of this study was to develop and evaluate a corrective and photoprotective makeup for patients with dyschromias. An emulsion was prepared and pigment mixtures were incorporated in the formulation, producing five shades of corrective makeup: BEIGE (I, II, III), BRONZE and TAN. The sun protection factor (SPF) and UVA/UVB ratio of the corrective makeup were determined using spectrophotometry with a Labsphere® analyser. The spreadability, occlusivity, stability, and photostability of the photoprotective formulations were also evaluated. For all formulations there was no statistical difference among them (p > 0.05) in terms of spreadability, occlusivity and SPF. They were considered to be photostable under solar radiation, with variations in SPF... |
