What people say about this formula

4.7 average · 24 reviews

  • “I add this product to every skin care product that I use. My skin at age 52 looks 35. I can only think this is the reason that I still look so young. I am proud of how my skin looks. I have noticed that my skin is so much firmer. Just use the amount that it states. This will last a long time. Highly recommend this.”

  • “I am about to turn 40 and I have used various serums over the last few years from low end to high end. I then started using a copper peptide serum (which was so expensive) but gave great results — and then I found this! It is a lovely consistency, absorbs well and is just perfect for my skin and is just as good as the one at 4x the price. I have just placed my order for my 4th bottle — I use this night & morning and a bottle using 1-2 pumps lasts me around 3 months. Just brilliant all round.”

    Linda H

  • “After just one week my skin feels better, plumper and more moisturized! The fine lines on my forehead are already diminished! Cannot live without this going forward!”

    Patricia W

  • “After a few weeks of using, I noticed that my skin had a firmer more supple appearance and my fine lines on my forehead are reduced in size and depth. My skin is smoother overall and I think this is a very effective and wallet-friendly treatment.”

  • “This copper peptide complex changed my skin by evening it out, smoothed fine lines and lightened some dark spots. It’s a must have in my routine.”

    Cynthia C

  • “After four weeks of consistent use, my skin looks healthier, smoother, more hydrated, and more radiant. The serum absorbs quickly, feels lightweight, and leaves my skin refreshed without any greasy residue. My complexion looks more even and feels firmer overall. I’m excited to continue using it and would definitely recommend it to anyone looking for a simple serum that delivers noticeable results.”

    Jenice K

  • “It’s a thick, hydrating serum that was great in the cold months for me. Skin felt very plump, hydrated, and calm when layered first before my adapalene and moisturizer.”

    Brenda M

  • “I love this serum so much. I have sensitive skin, and use this once a week so it lasts a while, and it makes such a big difference. Smooths lines, cleans pores, and evens skin tone.”

    Margaret T

  • “My skin looks more radiant and so clean. Love this product — it is light and good to my skin.”

    Diane G

  • “I switched to this after using other serums which didn’t seem to make much difference to my aging skin! I was slightly disappointed at first because I suppose I expected immediate results. However, with continued use of approx 9 months now I have really noticed a difference in my skin. It’s smooth, soft, fine lines have been dramatically reduced and even reduced the crow’s feet around my eyes. I try to use morning and night, it’s good for me because it’s little effort for great results. Highly recommend!”

    Janet R

  • “Great serum for dry sensitive skin. No fragrance and non-irritating.”

  • “I have noticed that my skin’s texture and firmness have improved since I have been using this product. The fine lines seem a little smoother and it does not irritate my skin.”
