This non-comedogenic formula incorporates a number of ingredient technologies and has been clinically proven to reduce blemishes by 79% after 3 months. It contains a blend of resurfacing acids to decongest pores, zinc gluconate and glycyrrhetinic acid (derived from liquorice) to calm redness and inflammation, and Bioderma's patented Fluidactiv technology to regulate the composition of the sebum (the skins natural oil), preventing future breakouts.
