Cell Cycle Catalyst is a daily use, layerable serum clinically proven to boost results. Powered in part by a 7.7% multi-acid complex (alpha hydroxy and beta hydroxy acids) and 1% Taurine, Cell Cycle Catalyst is clinically tested to gently peel and enhance cellular turnover at the skins surface to smooth texture, improve the appearance of discoloration, and the look of visible lines. This exfoliating serum helps maintain optimal hydration to support a healthy skin barrier.
