Skin Ceuticals Cell Cycle Catalyst

A potent, layerable serum to accelerate skin renewal cycles and amplify anti-aging results. Powered in part by our 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 skin’s surface to smooth texture, improve the appearance of discoloration, and the look of visible lines. This anti-aging exfoliating serum helps maintain optimal hydration to keep a healthy skin barrier.

Cell Cycle Catalyst is an optimal first step to boost the instant results of an anti-aging routine. It can also be used to prepare skin ahead of professional treatments.
