I love the Revolution Skincare product formulations. They always work perfectly for my combination-oily skin and perform as well as high-end skincare at a much preferred price point. This copper peptide serum is the first product I used and the one that introduced me to this line. In conjunction with daily sunscreen use and moisturizer, I noticed an improvement in hydration and facial firmness in one bottle. My skin definitely glows and looks great when I use this. It is a cost effective alternative to other “copper peptide” products that currently retail for more than 3x the cost. If you are interested in the benefits of a copper peptide in your skincare, this is the product I recommend!
