The Retinol Boosting Complex enhances the efficacy of pure Retinol through three plant-based ingredients: Marine Bio Retinoid (helps the formula work sooner by providing Vitamin A compounds that boost Retinol potency), Cyclic Peptide (derived from Prince Ginseng roots and improves conversion of Retinol to Retinoic Acid), and Mastic Gum Liposome (helps prevent Retinol breakdown and prolongs its effectiveness).
