Review on PCA SKIN Rejuvenating Serum 1 oz - Powerful Anti-Aging Antioxidant & Peptide Formula Suitable for All Skin Types by Alicia Pattinson

I really like the Pca line and notice a difference within a few days of using their serums, especially with my pore size. The only problem is that you have to keep using them, and it can get expensive (although some serums usually last for several months). As soon as I stop using serums my acne comes back, my pores look bigger etc. but they work and they work great if you use them specifically if you combine them with some of their other products.
