Improved efficacy and tolerability of retinoic acid in acne vulgaris: a new topical formulation with cyclodextrin complex ψ

Abstract

The topical RA/beta-CD complex, in hydrogel and moisturizing base, was more effective than the twice concentrated commercial RA product. There were few topical side-effects with this new formulation, which increases patient compliance. Topical RA/beta-CD (0.025% RA) did not significantly reduce sebum secretion but may help to preserve optimum epidermal moisture content with the proper base formulation. This is the first study in the literature reporting efficacy and tolerability of the topical RA/beta-CD complex in acne vulgaris. We conclude that the topical RA/beta-CD complex displays an improved efficacy and tolerability profile and is an effective treatment alternative for acne vulgaris.
