Combination effects of cosmetic moisturisers in the topical treatment of acne vulgaris

Abstract

Cosmetic moisturisers were applied to one side of the face of 18 male Japanese patients with acne vulgaris who were treated with a topical administration of adapalene and clindamycin phosphate gels. We assessed the alleviating effect of the moisturisers on the side effects of the treatment. The severity of acne and the number of inflammatory and non-inflammatory lesions were measured at 0, 2, and 4 weeks. The water content in the stratum corneum and transepidermal water loss were measured by comparing the moisturiser-treated and untreated sides of the face. The sensation of skin dryness and irritation on both sides of the face were assessed by the subjects. We observed that the use of moisturisers did not impact the efficacy of the standard topical treatment and they significantly improved the water content in the stratum corneum and the sensation of dryness. These results suggested that the use of moisturisers in combination with the standard topical treatment may improve adherence to therapy by alleviating the sensation of dryness.
