The Cell Cycle Catalyst treatment had great results on my skin.

I was surprised when I first opened this item. It is called a serum but there is almost no viscosity to it. It looks like clear water, it is so thin. It is also packaged in Skinceuticals amber glass bottle with a dropper to prevent UV degradation, which I love. I use it over freshly washed skin. The very first time I used it, I felt as if my skin showed less redness, which is an issue I face. The primary ingredients are alpha hydroxy and beta hydroxy acids so I do have to research what other products this can layer with. As marketed, it says the product will gently peel and enhance cellular turnover. To be clear, there is no visible peeling. I'm really kind of impressed because I thought my overall skin tone was noticeably improved after just a few uses.

The Cell Cycle Catalyst treatment had great results on my skin. The mornings after using this product (used before bedtime), my skin looked smooth, glowy, and radiant. However, this is a very thin formulation with very little glide, which didn't make it very enjoyable to use. The results were so lovely, however, I forgave the application issues entirely.
