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.
Most copper peptide serums contain less than 10 parts per million of GHK-Cu. That's not a treatment, that's a label.
Our serum uses 2% GHK-Cu, a concentration in line with the ranges referenced in published copper peptide research. Most serums on the market use a fraction of that.
GHK-Cu signals your skin to produce more collagen and elastin, the proteins responsible for firmness and bounce. Hyaluronic acid pulls moisture deep into the skin and holds it there, while glycerin and arginine help support your skin barrier.
Copper Tripeptide-1 (2%)
Supports collagen and elastin production for firmer, more resilient skin.
Hyaluronic Acid
Holds up to 1000x its weight in water for deep, lasting hydration.
Hydrolyzed Collagen
Small molecules that absorb easily to hydrate and smooth the skin.
Glycerin
Draws in and locks moisture into the skin, supporting the skin barrier.
Arginine
Supports the skin barrier and helps balance moisture levels.
1,2-Hexanediol, Carbomer, Water
Give the serum its lightweight texture and keep the formula stable and fresh.
Apply 2–3 drops to clean, dry skin every evening, before your moisturizer.

The science behind the formula
Backgrounds across dermatology, cosmetic chemistry, and skin barrier research.
Most copper peptide serums use GHK-Cu at 3 to 10 parts per million — a concentration so low it produces no measurable effect. BioGlo is 2% — roughly 200 to 700 times the concentration of most products on the market. The dose is the difference. It wasn't you. It wasn't the ingredient. It was the amount.
We had the formula tested by an independent third-party laboratory using HPLC — a method that confirms the exact molecular structure and concentration of GHK-Cu in the bottle. The Certificate of Analysis is available on this page.
Most customers feel skin is softer and more hydrated within the first week. Visible improvements in tone and texture typically begin around week 3–4. For firmness, elasticity, and reduction in fine lines, consistent use over 8–12 weeks delivers the most noticeable results. That's exactly why we offer a 60-day guarantee
The Ordinary Buffet + Copper Peptides is 1% GHK-Cu in a multi-peptide blend. NIOD CAIS retails at $90. BioGlo is 2% single-active, independently verified by HPLC, at $49.99 CAD. You're not paying for a name. You're paying for the dose and the proof.
Yes. Our formula includes panthenol and allantoin specifically to support sensitive skin. Copper peptides are generally very well-tolerated. We recommend patch-testing on your inner arm for 24 hours before full application. If you have a diagnosed skin condition, consult your dermatologist first.
2–3 drops is all you need for your full face and neck. Apply to clean skin before moisturizer. The serum works morning and night — morning before SPF, evening before your night cream. One 30ml bottle typically lasts 6–8 weeks with twice-daily use.
Yes — we offer free shipping on all orders, so the price you see at checkout is the price you pay. No hidden fees, no surprises.
