Rejuvenating Booster Shot M.D. Serum is a glow-lifting experience in a bottle. It visibly improves elasticity and helps repair the skin’s moisture barrier. Key ingredients include Phyto-PDRN for moisture barrier repair and proprietary hyaluronic acid for radiant, dewy skin. Hyper-EGCG provides more elasticity than retinol. It is suitable to use after a dermatological PDRN-based skin booster injection and is dermatologically tested for skin irritation.
