Technology: Contains 1% Liposomal GHK-Cu (Copper Tripeptide-1), Ceramides (NP, AP, EOP, Cholesterol, Phytosphingosine,) and Sea Kelp Bioferment. According to L. Pickart, controlled studies on aged skin with GHK-Cu (Gly-(L-His)-(L-Lys)) demonstrated that it has the potential to tighten skin, improve elasticity and firmness, reduces fine lines, wrinkles, photodamage and hyperpigmentation, which is why we chose to include it as an active in this serum. Paired with Sea Kelp Bioferment and a complete Ceramide Complex, this facial serum is an ideal companion to use with your Retinoid during your PM routine. Health Canada registered cosmetic #03584256

Why encapsulation is important: Studies have shown that although GHK-Cu is a small enough molecule to penetrate the stratum corneum, it tends to not readily absorb on its own. Topically applied GHK-Cu was found to have an average absorption rate of 0.6% - 2.8%. Various forms of encapsulation have been proven to increase not only penetration depth, but retention as well. The very best method has been shown with liposomal micro-ecapsulation which is the method we use in our serum. In a study by Ogorek et al published just this year, it was found that liposomal micro-encapsulation could increase GHK absorption and retention by as much as 5.8x.

Directions:Use morning OR at night (We recommend PM routine) for increased hydration resulting in noticeable skin plumpness and decreased texture. Use in any order of layering steps after cleansing (Typically Cu-2 should be applied before any oils, cream moisturizers or other emulsified products except in the case of retinoids). DO NOT use in the same routine as Vitamin C or LEAVE-ON hydroxy acid products (AHA/BHA/PHA including fruit acid complexes. Wash-off products are fine). May be used with Retinoids (Retinol, Adapalene, Tretinoin (Apply AFTER retinoid)). Safe to use on dry skin after wash-off cleansers containing hydroxy acids.

Great!

This is a wonderful serum. I use it every day, but also after tretinoin. Until recently, I used GHK-cu serum from a popular Canadian brand, but this is incomparably better. It's not cheap because I have to pay tax on it in Poland, but it's still worth every penny. I love it.

Best addition to my routine

I am very suspicious of skin treatments because social media influencers often get paid to hype up a products that don’t work at all. But this stuff blew me away. I’ve been using prescription tretinoin and vitamin C for a couple of years now but adding this to my routine propelled my skin to the next level. It actually made such a difference when paired with my other stuff that I almost can’t believe it’s real. At first I found the price a little eyebrow raising but now that I’ve used it it’s so worth it I will never buy anything else. 100% worth the price. Fantastic product. And to boot it came in adorable little hand wrapped box with a note which I really appreciated.

Actually Really Works

Honestly surprised at how well this works. Bought this for the copper peptide benefits and I don't think I've ever had a product work so fast and so well. Noticeably smoother skin, incredible softness, and great price compared to similar products that are unnecessarily marked up. Found the brand through TikTok and loved the owners clear breakdown of ingredients and their uses. Absolutely ordering again, keep it up!

Absolutely love this copper peptide

I'm on my 3rd bottle of this serum and absolutely am in love with it. I've tried a few other peptide serums including Depology Matrixyl and The Ordinary's Multipeptide Serum and feel like I wasted my money on them. This peptide serum is the only one that I can physically see changes. My skin is tighter, and more even and the red patches I used to get on my chin and cheeks - Gone!
