Effectiveness of a formulation of glycolic acid with vitamin C for reducing visible signs of photoaging

RATIONALE AND OBJECTIVES

• Middle-aged individuals, especially those living in urban areas, often have dull complexions with solar lentigines caused by the exposome, especially chronic UV exposure and potentially pollution.
• Ampoules have been developed with a minimalist highly effective formula, including a glycolic acid complex of 4% glycolic acid, 1% citric acid, and 5% HEPES, for the peeling effect; natural vitamin CG for the correction and prevention of dark spots; hyaluronic acid; and Vichy mineralizing water recognized to be a volcanic mineralizing water (Liftactiv Glyco-C [Vichy]).
