Powerful Strength Line Reducing Concentrate

This product has a fixed position in the pantheon of all-time greats, not even kidding. If it had an Instagram bio, it would read something like, "brightener, hydrator, wrinkle reducer, skin protector all in one." Two types of vitamin C go in - 10.5% L-ascorbic acid and 2% of a derivate vitamin C. Bringing down the irritation levels and stepping up hydration is hyaluronic acid. After cleansing and toning, apply the serum on dry skin and dab in until it is absorbed. Make sure to top it off with sunscreen during the daytime. Avoid layering heavy exfoliating products like AHAs, BHAs and retinol with this one.
