摘要

The method of tape stripping in combination with spectroscopic measurements is a simple and noninvasive method for the analysis of dermatopharmacokinetics of cosmetic products and topically applied drugs. The absorbance at 430 nm was used for the characterization of the amount of corneocytes on the tape strips. It was compared to the increase of weight of the tapes after removing them from the skin surface. The penetration profiles of two UV filter substances used in sunscreens were determined. The combined method of tape stripping and spectroscopic measurements can be also used for the investigation of the dermatopharmacokinetics of topically applied drugs passing through the skin. Differences in the penetration profiles of the steroid compound clobetasol, applied in the same concentration in different formulations on the skin are presented.
