Copper Amino Isolate Serum 2:1.

"This is a copper peptide serum that I talk about all the time here on my channel and it's one of the best in my opinion"

"This is honestly one of the best copper peptide serums I have ever used. I see quicker results with this serum. And this serum truly performs in terms of firming and just giving more of that rejuvenated youthful appearance to the skin."

"I do feel like this one works a little bit better and the texture of this is like water whereas this one is more of that jelly type of texture that gel"

"I also quite enjoy the neod copper amino slate serum. Like, there's a lot that I do like."

"I love that one as well but this one is a little bit more affordable"

"I also love the neod copper aminoit slate serum. Sometimes I like to alternate between the two and this is outstanding and a lovely serum for signs of aging and stimulating collagen."

"This is one of my favorite copper peptide serums, and this really performs. This firms the skin."

"This one at the end of the day performs better and quicker from my experience with it"

"You can't go wrong with either one so yes I will be continuing on with this for sure"

"I do feel like this one works a little bit better because of the other ingredients that are in here"

"I'm going to rate this serum a 10 out of 10."

"NIOD Copper Peptide Aminoate is one of my top performing serums that I love using on a weekly basis, sometimes every day. Although I have a lot of favorites when it comes to copper peptides, this is my top pick, the one I've been using the longest and will always continue to use. It is truly 10 out of 10, this performs really well. I love how thin and lightweight it is, it's truly like water. Copper peptides help stimulate collagen, firm the skin and soften fine lines, and I think this one from NIOD is one of the most advanced formulations I've ever used. I saw results pretty quickly in terms of firming the skin when I was consistent with it, and even after trying other copper peptide serums I always go back to this one because it performs, and it performs really quickly. This is definitely worth the money in my opinion."

"The NIOD Copper Amino Isolate is amazing, I love this product a lot. Copper peptides stimulate collagen and firm the skin, and help address fine lines and premature signs of aging. I've been using copper peptides for several years now and it's all I use now because it really does perform, and I refuse to remove it from my routine."
