Summary

Acne is a chronic inflammatory dermatosis of the pilosebaceous unit. Topical treatment is the first choice in mild and moderate cases of acne, especially topical retinoids. Although topical retinoids are very effective in the treatment of acne, local cutaneous irritation including burning, itching, erythema, peeling or dryness, is observed in a considerable number of patients, resulting in low patient compliance, compromising the efficacy of the therapy.

Several approaches have been proposed to address these concerns, including the use of esters of retinoic acid (RA) and RA precursors, such as retinol and retinaldehyde, or novel drug delivery systems, which present the potential for controlled release, in turn reducing the aforementioned occurrences.

Encapsulation of retinoids into vesicular carriers as liposomes and ethosomes and nanoparticulate carriers can significantly improve their effects for the treatment of acne compared with commercial formulations , providing better tolerability of irritating retinoid.

The aim of work is to assess the efficacy and tolerability of the topical application of Retinyl Palmitate-loaded ethosome formulation in the treatment of acne vulgaris in comparison to conventional formulation of classic retinoids
