Younger-Looking Skin, Powered by the Most Researched Peptide in Skincare — GHK-Cu
Formulated with 2% GHK-Cu (copper tripeptide-1), hyaluronic acid, and hydrolyzed collagen, this nightly serum works to visibly soften the look of fine lines and support firmer, more youthful-looking skin over time.
You've probably already tried it all: the expensive creams, the serums with endless ingredient lists, the "miracle" products that do nothing after two weeks.
The problem usually isn't that you're using too few products. It's that most serums target the wrong layer of the skin, they hydrate the surface but do nothing for what's happening underneath: collagen and elastin production, which naturally slows down starting in your mid-20s.
The result: no matter how good your routine is, skin can start to look dull, feel less firm, and fine lines become more visible.
There's one ingredient with decades of scientific interest specifically around this problem: copper peptide GHK-Cu.
Meet Beyond Protocol — 2% GHK-Cu Copper Peptide Serum
GHK-Cu isn't a new trend. It's a peptide complex that has been the subject of dermatological research into skin repair and collagen production since the 1970s. We've formulated it at a concentrated 2%, paired with three ingredients that support the effect.
| Ingredient | What it does |
|---|---|
| Copper Tripeptide-1 (2%) | Supports the skin's natural collagen and elastin production |
| Hyaluronic Acid | Draws in moisture for deep, lasting hydration |
| Hydrolyzed Collagen | Smooths and softens the skin |
| Glycerin & Arginine | Support and strengthen the skin barrier |
How to use it: Apply 2-3 drops to clean, dry skin every evening, before your moisturizer. Avoid direct contact with eyes. As with any new skincare product, we recommend a patch test before first use.
Not every serum with "collagen" on the label actually does something.
Concentration that matters. 2% GHK-Cu is a level at which the ingredient is actually studied in research, not a token trace at the bottom of the ingredient list.
The right combination. Copper peptide works on repair from within; hyaluronic acid and glycerin keep skin hydrated and supple in the meantime, so it doesn't take weeks before skin already feels softer.
Consistency over complexity. One step, every evening. No complicated 10-step routine, just the ingredient that matters, at the right dose.
