"This is one that I've been wanting to try for a long time by Allies of Skin, their copper peptide serum. They also have very stacked ingredient decks. And this one has 2% ectoine copper peptides, the copper lysinate complex, acetyl hexopeptide 8, plus 1% copper tripeptide complex. So a couple different types of copper peptides in here. Excited to try this too, and I've heard great things."

"It's beautiful packaging, the formulas are very thoughtful, very complicated, and I just have a hard time bringing myself to buy it. [...] It's an incredible copper peptide serum, but it's 199 dollars, so what I'm looking for is a very deep discount, 20 to 30 percent, to splurge and indulge in this copper peptide product."

"Copper peptides have really profound benefits on the skin, and that is a beautiful formula. I spent the last hour looking for it in my house and couldn't find it, but it's just absolutely beautiful packaging and an absolutely beautiful formula. Right now the price point on those, if you had a problem with Skinceuticals you'll have a problem with this, they're nearing two hundred dollars per product, however they are top top tier in terms of innovation, formulation and aesthetics."

THE BEST HYDRATING SERUMS | DOCTORLY UNSPONSORED REVIEWS

"This is a copper tripeptide and ectoin advanced repair serum. Ectoin is really where you're getting that hydration from. You're also getting some other hydrating ingredients in this formula as well. But you also get that compounded effect of the cetal hexapeptide aka giralene. And you also have two forms of different copper peptides in this formula. It's a beautiful blue serum and [...] it's super hydrating. It's a super hydrating formula."

"I did empty the Allies of Skin Copper Tripeptide and Ectoin Advanced Repair Serum, which I did share in my Epic Empties video, and I told you like I didn't want to like it, but I did. And I hated that I liked it because it's so expensive and that while it was gifted to me by the brand, this isn't really something that I care to afford. [...] It's just like it's a little too rich for my budget."

EPIC SKINCARE EMPTIES | Start Fresh Moving Edition

"This is a pretty good peptide product. I do think that this is a good preventative serum. I do feel that this definitely rejuvenates the skin, which is something that peptides and copper peptide in general can do for the skin that people tend to overlook. We're all about that collagen stimulation, but just the fact that it can help with skin tone and texture and it can just improve and refresh your overall skin quality."

"I really like this product. I think it is a great peptide product. [...] They're using a 2% copper lysinate complex, which is actually a complex of amino acids that really help to support the skin, skin hydration, skin barrier, and it can help to improve the signs of aging including skin density and firmness. They're also using a 2% complex of acetyl hexapeptide 8, which is a Botox peptide. It actually helps to give a really nice effect to the skin to lift and firm it pretty quickly."

"I don't think it's a replacement, I do think it's different though. I also like the texture, it is bouncy, it's pretty substantial, which makes it really nice, especially in the drier months because you really feel like it's got some skin plumping hydration. There's also just a really nice bouncy slip to it during application which I enjoy. It's quite lipid, feels quite moisturizing, and it does sit on the skin, it's kind of somewhere in between."

"This is different in many ways from the cis-3 so it's not like I will be replacing one for the other but I'm really enjoying using this right now. This is full of age defensive peptides. In my experience this has also been really fast acting with skin that is very sensitive. The texture has the kind of viscosity to it that I really love so when you're applying it on your skin there is some slip and a little bit does go a long way. It is so hydrating and comforting."

"This by Allies of Skin is recently released, it's their Copper Tripeptide + Ectoin Advanced Repair Serum, which also has peptides that are going to help collagen production. So if you're not into the thicker texture or you live somewhere very humid but you want to get those peptides in, this is a nice alternative."

"I also really like the Allies of Skin Copper Peptide. [...] It doesn't matter what copper peptide serum you're using, pair it up with a growth factor serum, [...] copper peptides work better and quicker than just regular peptides from my experience."

"And then over time, when you are consistent, it really firms. Copper peptides in general firm the skin, and it helps to soften some of those premature fine lines as well. And then again, it will collagen bank, and it will help to stimulate collagen. This is 10 out of 10. Honestly, one of the nicest copper peptides I've ever used. [...] Copper takes your skin to the next level, and it pairs well with growth factors and other types of peptides."

"This is one of my favorites. I really like this one for morning. Sometimes I will use this at night time. I'm very careful on how I use copper peptides because there's a lot of ingredients that can conflict with the copper ingredient, and then it just won't be as effective on the skin. So I usually only pair this up with growth factors or other peptide serums, or [...] sometimes I will even use this with a vitamin C derivative in my morning skincare routine."

"This is a very firming serum. And this is also very hydrating. It doesn't peel with skincare products. It layers up nicely with other peptide serums, other hydrating repairing products. It is a friendly product that pairs up nicely with a lot of things including sunscreen, including makeup because it is a product that can be used twice a day if you wish. This has 2% ectoin, which is an ingredient that is a stress molecule. This is going to protect your skin and repair it from pollution."

"I also quite enjoy the Allies of Skin Copper Tripeptide and Ectoin Advanced Repair Serum. I actually just started using this one not long ago, and this is also really impressive. This one is a little bit more advanced than the ordinary one in my opinion. This one has an ingredient called ectoin in it. And ectoin is a hydrating repairing ingredient. So, not only does copper peptides help with skin repair, so does ectoin, but then there's a lot of humectants in here."
