Topical Boswellic acids for treatment of photoaged skin.
Boswellic acids (BAs) are pentacyclic triterpenes extracted from the gum resins of the tropical tree Boswellia serrata. They are orally administered in traditional Indian medicine for the treatment of several inflammatory disease and cancer because of their anti-inflammatory and immunomodulatory activities as well as stimulatory effects on fibroblasts. The present authors have investigated efficacy, tolerability, and safety of a base cream containing 0.5% BAs in the treatment of clinical manifestations of photoaging of facial skin with a randomized, double-blind, placebo-controlled, split-face study. Fifteen female volunteers applied the creams with or without BAs on the half sides of the face once daily for 30 days. Significant improvements of the Dover's global score for photoaging, tactile roughness, and fine lines, as well as, with noninvasive diagnostic techniques, an increase of elasticity, a decrease of sebum excretion, and a change of echographic parameters were observed with topical BAs in comparison with placebo. The treatment was always well tolerated without adverse effects. The present findings seem to indicate that topical application of BAs may represent a suitable treatment option for selected features of skin photoaging.
