After age 20, your body loses 1-1.5% of its collagen every year. By 50, you've lost nearly half. That's why fine lines deepen, skin thins, and firmness fades — no matter how much moisturizer you apply.
Most serums mask the symptoms. They hydrate the surface while the structural damage continues underneath. The only way to reverse visible aging is to reactivate the biological processes that built your skin in the first place.
That's exactly what GHK-Cu does.
ingredients
GHK-Cu is a bioactive copper peptide your body produces naturally — then loses up to 60% of between ages 20 and 60. Applied at 1% pharmaceutical-grade concentration, it reactivates over 4,000 genes involved in collagen synthesis, elastin production, and structural skin renewal. This is the only topical ingredient scientifically proven to reverse the root cause of fine lines — not mask them, not plump over them — actually reverse them at the cellular level.

Discover authentic reviews from customers who noticed smoother, healthier-looking skin.
Crepey neck & forehead lines — visibly softer in 2 weeks
“I've spent thousands on luxury creams for my skin. This tallow + copper peptide combo is different — it gets IN. After just 2 weeks, the crepey skin on my neck and deep forehead lines are noticeably softer. It's healing the skin, not just coating it.”
Forehead lines almost gone — skipped Botox thanks to this
“I felt very self-conscious about the lines on my forehead. I was already using tret and SPF every single day but they wouldn't budge. I was seriously considering Botox until I found this serum. In 2 weeks I noticed my face getting smoother, and after a month the lines have almost completely faded. I feel so much more confident.”
Rough leathery skin turned healthier in just 2 weeks
“Never wore sunscreen a day in my life. My face looked like leather — rough, dark spots, deep lines everywhere. I figured the damage was done. Two weeks in and my skin already looks smoother, the rough patches have softened, and my complexion looks healthier than it has in a long time. Not going a day without this stuff.”

Everything you need to know about GHK-Cu and our serum
GHK-Cu (copper tripeptide-1) is a naturally occurring peptide in the human body, deeply involved in skin renewal and collagen signaling. As we age, our levels drop by up to 60%. Our serum reintroduces it topically at a precise 1% concentration, supporting your skin's natural renewal and repair processes.
Most customers notice improved hydration and glow within the first few days. Visible improvements in fine lines and texture typically appear within 2 weeks. Full transformation — firmer, smoother, more radiant skin — is usually achieved by 4-6 weeks of consistent daily use.
Yes. Our formula is specifically designed to be gentle. It contains no sulfates, silicones, parabens, fragrances, or essential oils. There is no redness, peeling, or adjustment period. GHK-Cu is naturally present in your body, making it well-tolerated by all skin types.
Cleanse and dry your face. Apply 2-3 drops evenly across face and neck. Massage gently until fully absorbed. Use once daily — morning or night. The entire ritual takes about 30 seconds.
Absolutely. Apply the serum on clean skin, then follow with your regular moisturizer and/or sunscreen. It plays well with most skincare products and can simplify your routine.
We offer a 60-day money-back guarantee. If you don't see results, simply contact us for a full refund — no questions asked. We believe in our product and want you to experience the difference risk-free.
Our serum uses pharmaceutical-grade GHK-Cu at 99% purity in a precise 1% concentration — backed by over 40 years of peer-reviewed research. Unlike many serums, our clean formula has zero irritants, making it effective yet gentle enough for daily use.
Yes — and the mechanism is real. PepDerm works at the cellular level, reactivating the genes that drive collagen and elastin production. The visible result: firmer skin, softer lines, and a more refreshed appearance. Most users notice a measurably more youthful look within 2–4 weeks of consistent use.
Better skin quality naturally enhances your features. PepDerm improves skin firmness and elasticity — which reduces laxity and sagging along the jaw and cheeks, making your face look more structured and defined over time. It's not a sculpting device, but the improvement in skin quality does show in facial contours.
Most users notice improved hydration and a softer texture within the first week. Visible firmness and smoothing — especially in fine lines and rough patches — typically appear within 4–6 weeks of consistent daily use. Results compound over time as collagen rebuilds.
Dermatologist-trusted ingredients — safe, effective, and well-researched. Full list: Copper Tripeptide-1 (GHK-Cu), Hyaluronic Acid, Glycerin, Aloe Vera Extract, Vitamin B5 (Panthenol), Vitamin C & E Antioxidants, Propylene Glycol, Carbomer. No fragrances, parabens, or silicones.
One bottle lasts approximately 30 days with regular use. We recommend applying 2–3 drops to clean skin once daily — morning or night. A little goes a long way, so resist the urge to over-apply.
