What the gurus are saying

Gurus consistently praise this serum for delivering visible firming and lifting results within weeks of regular use, crediting its peptide blend and copper delivery technology. The standout benefit is pore refinement and skin thickness without heaviness. The main hesitation is price (around $60-$90 per bottle), though reviewers who've tested it say results justify the cost for those with budget flexibility.

"The Neostrata product uses some trademarked technology they actually spent so much money on, going through the trademark process, which is a sign that it's good at getting those peptides to where they need to be in the skin to give you maximum results. With the Neostrata product you're getting a good dose of peptides but that technology really helps them work extra hard for you. It's a nice middle ground, not the cheapest product out there but also not super expensive, so it's a good mid price point. 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 some others, it uses that technology to really get maximum results for the skin. It's a really nice option."

"It's a collagen stimulating peptide that signals to our body to create collagen, but it also is a carrier peptide for copper and it helps deliver the copper deeper into the skin where it can create more meaningful results. So 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, but 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."

Skincare That Actually Firms Skin!
"It's an expensive product, about $62 for 15ml of product or $93 for a 30ml bottle, but the reason I bring it up is because it works. I would never recommend something at that price point if I didn't have personal results with it. This firms the skin, makes it feel thicker but in a good way, thicker and firmer and more lifted. After a couple of weeks of consistent use it absolutely firms the skin. It has 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 look really smooth, really lifted, feels thick, feels firm, and that really comes down to those peptides that are helping with the structural integrity of the skin. The peptides help keep the pore from sagging, which is why we're seeing those results with the pores. It's also overall helping the skin to feel more firm and lifted."
