Combination therapy with hydrogen peroxide (4%), salicylic acid (0.5%) and D-panthenol (4%): efficacy and skyn tolerability in common acne vulgaris during sun exposure period

Acne vulgaris is a disease of the sebaceous follicle which affects up to 90% of adolescent patients. Topical retinoids, benzoyl peroxide and antibiotics are the main treatments for mild to moderate acne vulgaris. The use of such topical treatments is often associated with local irritation and dryness making the skin more sensitive to the sun. The aim of our study was to assess the efficacy and skin tolerability of a fixed-dose combination therapy with hydrogen peroxide (4%), Salicylic acid (0.5%) and D-panthenol (4%) (HSD) gel, in mild-moderate acne vulgaris, during the period of sun exposure.
