Customer Reviews

"Amazing results. I've been using the firming serum for about a month now. I've noticed my acne scars are not as bad as it applies to be. Before, my eyelids were saggy, and I've seen lines under my eyes. I ran out and just purchased a second bottle. I'm in love with this serum." – ★★★★★ Der L., Verified Buyer

"Didn't think it could be this good. Tried because I love all zo products. But I love this. I know it is for firming but I also haven't had the crazy dryness I typically get from winter that wreaks havoc on my skin. And people have told me I'm glowing. Is it supposed to do all these things? And works well with retin a too! It's a keeper!" – ★★★★★ Heidi, Verified Buyer
