NeoStrata Firming Collagen Booster helps boost your skin’s natural rejuvenation cycle. Healthy, stronger collagen makes your skin feel firmer and appear more lifted. This booster’s advanced formula includes three clinically proven technologies, each with a unique action to synergistically target new and existing collagen. They preserve the existing collagen structure by inhibiting MMP enzymes which break down collagen. They also help stimulate new collagen synthesis. In addition, the chemical building blocks of collagen work to help build collagen.
