"If you wanted to completely splurge and step it all the way up, the NIOD Copper Amino Isolate Serum is the cult favorite in this category. It retails for $93 for a 1 oz bottle, they do have a 15 ml one, but proportionally to the volume you get it's significantly more expensive. It delivers a really high concentration of copper peptides for people who want to lean in all the way."

"This one is the thinnest of the copper peptide serums I use, truly like water, and I really like this serum for that reason, especially for the summer months because of how lightweight it is on the skin. It never causes peeling, it's never sticky or tacky, it truly dries down like your skin. I do find the Ordinary and the Allies of Skin [...] to be more hydrating on the skin over the NIOD, so it depends on your skin type and what you're looking for."

Once you open this up, you have about six months to finish it. This one has a really nice texture that spreads across the skin. It's hydrating. It's not sticky or tacky either."

"The ingredients in here are more advanced. I do find that this works a lot quicker but it's very comparable and similar to the ordinary. This one is more expensive. This one has more of that gel type of serum, it kind of mimics hyaluronic acid in the way of texture. So it just depends on maybe what consistency you like better, what your budget is, but this one is exceptional if you're looking for a copper peptide."

"This is the Niod Copper Amino Isolate Serum, which is 93 bucks. The main difference between this and the Ordinary copper peptide serum is the texture. This one's got a very water-like texture, so it's pretty easy to fit into most routines, whereas the Ordinary has kind of a gel serumy texture. It's got 1% copper peptides, tripeptide 29, which they say helps with collagen production, vitamin E, and retinol peptide 189, which is claimed to function similar to retinol."

"This has been a staple in my routine for years. [...] I think this was one of the first peptide serums I ever used and I've absolutely loved it. It's not the cheapest product out there, but it's definitely an advanced formula that makes sure those peptides get to where they need to be in the skin in order to deliver maximum benefit. Such a great product, such a great formula, and definitely for people that have used peptides for some time and want to kick it up a notch."

"It's also got a great blend of peptides in here which are really going to double down on that collagen production. This is amazing. And again, because it's part of that Ordinary family, they currently have a 23% off sale on this product, which will bring that price point down a little bit. Full price, it is actually a little bit out of the reach of a lot of people, but with that sale on, it will make it slightly more accessible."

"If you prefer something that isn't in a lipid base but is more traditional serum then the Copper Amino Isolate Serum is a great option.

This is a really great anti-aging option."

"It has the same great copper peptide blend as the lipid but it's in a more watery serum base. This is really going to come down to preference in terms of what you like in terms of texture. [...] If you want something that sinks in super quick then the serum might be more for you. I tend to mix and match between the two depending on what my skin needs. In summer I will go for the serum which is more lightweight, in winter I'll go for the more heavy duty lipid."

"The best of the best in copper peptides is the NIOD Copper Amino Isolate Serum 3:1. It's got technology in here that makes sure those copper peptides get to where they need to be in order to deliver maximum results. It's also beautifully hydrating. However, it comes with a higher price point, so whilst this is absolutely worth every penny, for those of you that are on a budget or maybe don't want to stretch this price point, I understand."

"I find it's a nice middle ground, it's not the cheapest product out there but it's also not super expensive so it's a good mid price point and one that I definitely definitely love. The copper peptides in here are the ones that stand out and whilst it doesn't have quite the same advanced blend of different firming peptides as the first two, it uses that technology to really get maximum results for the skin and so it's a really really nice option."

"This is NIOD's copper amino isolate serum, and I didn't feel like it did that much for me. [...] I really like peptide ingredients and copper peptide is supposed to be an incredible one, but when I looked into the data there isn't much research on copper peptides. My biggest issue though is how runny it is, it's incredibly unpleasant to use, [...] nearly unusable, and it's still not inexpensive. So that's a no for me."

"I really like the combination here, there's some other peptides in the mix. This is a very expensive serum that is up in the like the $90 range. It's very expensive, it works. This is one of the very few expensive products where I would say if it fits your budget go for it. I don't think that you will regret it. It will show you results. It made my skin feel so firm so fast, amazing."

"This firms the skin. It makes the skin feel [...] thicker, but in a good way. It feels thicker and firmer and more lifted. [...] After a couple of weeks of consistent use, it absolutely firms the skin and it does have this really interesting refining quality to the skin. If you have enlarged pores, it really helps to smooth those and make them look more refined and slightly tighter. It makes your skin just look really smooth, really lifted."

"As far as copper tripeptides go, there hasn't been a single formula that can beat this for me. [...] This is all about skin optimization, just helping your skin function more effectively and efficiently, but also this promotes good collagen for firmness and elasticity. It's always been hard for me to describe, but it's an overall noticeable improvement, not just in the texture or the way my skin feels, but also just in the way it looks."
