SkinCeuticals Cell Cycle Catalyst
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.
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.

I really like this serum. It is very thin and watery, which I like because it is easier to layer with other products and feels light on the skin.
The skin feels silky while using it and helps to correct the skin scars from acne faster
Since starting the Skinceuticals skin care line, I have had several people ask me what I use on my face and whether it is a new makeup or product. I tell anyone who asks about Skinceuticald and specifically Celll Cycle Catalist and Ptox, two of my favorites! Leaves the skin smooth and brighter!
