<i>In Vitro</i> Evaluations for a New Topical Anti-Aging Formulation

Abstract

The study aimed to evaluate the in vitro properties of a new gel formulation (P-3086) as anti-aging treatment. Two in vitro methods aimed to assess and compare the efficacy of the gel formulation in reducing oxidative damages, artificially induced by UVA on skin-derived keratinocytes and in promoting the synthesis of collagen, compared with other four formulations. P-3086 reduced reactive oxygen species production after UVA stress with the highest effect observed at 0.016 mg/ml and 0.031 mg/ml concentration. P-3086 also promoted the collagen synthesis faster when compared with other formulations. The new gel product, based on hyaluronic acid, Vitamin E and <i>Humulus lupulus</i>, showed a good efficacy as anti-aging effect reducing the oxidative damages derived by the action of ROS, moreover stimulating the synthesis of one of the components of the connective tissue, the collagen.
