The vitamin C serum is the first of CosRx’s three Real Fit line products. The Real Fit line provides three options, vitamin C, E and retinol, allowing users to choose depending on their skin type and preference for main ingredients. CosRx says its formulas have been created at optimal concentrations, with maximum purity to enhance potency and effectiveness whilst minimizing side effects.
The sold-out Real Fit Vitamin C Serum C-23 contains 99% pure vitamin C. According to the brand, it helps to even skin tone and increase antioxidant activity to protect the skin from fine lines and reduce the appearance of dark spots. It also includes propolis extract to counteract the dryness caused by vitamin C and patented technology using Aronia melanocarpa fruit extract and Hippophae rhamnoides extract to stabilize and increase efficacy.
CosRx’s three Real Fit vitamin serums are produced in a limited quantity to maximize the effect of vitamins by preserving them in a fresh state. The products are available at CosRx’s website.
