Powered by a 15% vitamin C complex with three stabilised forms of the active, NIP+FAB’s new Vitamin C Fix Concentrate Extreme 15% is a reformulated take on the brand’s best-seller. This powerful, yet gentle concentrate features STAY-C© 50, L-VCG and SpecWhite VCE, three stable forms of vitamin C that are said to offer optimal efficacy and delivery of actives to the skin. The lightweight formula seeks to protect the complexion from urban pollutants and aggressors, while visibly brightening and unifying the skin tone for a stronger and smoothing-looking result.
