I hear so many good things about both of these products. Which one is better? Can you use both? Has anyone used one of these and had bad results? I think I'm just basically confused about which one I should buy. I would love to hear what everyone thinks of these - Thx!
copper peptide serum is definitely something i would recommend i've been using it for about 3 months and i can't believe how much it's helped with leftover red marks. I also do a lactic acid peel once a week and along with CP serum it's a good combination for renewing the skin.
