RoC Retinol Correxion Line Smoothing Night Serum Capsules are designed to improve the look of collagen-depleted skin. These capsules are sealed tight for optimal freshness and are powered by concentrated pure RoC Retinol and a bio-derived antioxidant that is twice as effective as Vitamin E. The lightweight fluid drenches the skin and dries to a silky finish. Clinically proven results show that 97% of users had smoother skin after one night, 63% more hydrated skin after one week, and visibly firmer skin by 30% after four weeks. The product is dermatologist tested and fragrance-free.
