Cell Cycle Catalyst is a daily use, layerable serum clinically proven to boost anti-aging 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 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 support a healthy skin barrier. Cell Cycle Catalyst is an optimal first step to boost the results of any anti-aging routine. It can also be used to prepare skin ahead of professional chemical peels. Catalyst is an extremely gentle formula and a great option for those who cannot tolerate retinols, retinoids, glycolic acid, etc. You may experience a slight adjustment period, which is completely normal when using an acid-based product.
