Peptide Skincare Serums
Concentrated GHK-Cu copper peptide serums, formulated as a single deliberate step in a daily skincare routine.

Copper peptide skincare, simply put
GHK-Cu is a copper tripeptide — three amino acids bound to a copper ion. It has been studied and used in cosmetic chemistry for decades, which is why copper peptide serums have become a fixture of peptide skincare rather than a passing trend.
A GHK-Cu peptide serum is applied as a few drops on clean skin and left on. Our formulas keep the ingredient list short on purpose: the copper peptide, purified water, hyaluronic acid, and vegetable glycerin to carry it comfortably. The more advanced option adds SNAP-8, a second cosmetic peptide.
These are cosmetic products for external use. They are not dietary supplements, and they are entirely separate from products designated Research Use Only.
How the serums are built
Concentrated drops
Three to four drops on clean skin — a serum, not a lotion.
Peptide-led formulas
GHK-Cu is the headline ingredient, not an afterthought on the label.
Short ingredient lists
Copper peptide, purified water, hyaluronic acid, vegetable glycerin.
Built for daily use
One quiet step that fits either end of the day.
Peptide serums: common questions
- What is a GHK-Cu serum?
- GHK-Cu is a copper peptide — a short chain of three amino acids bound to copper. A GHK-Cu serum is a leave-on topical cosmetic formulated around that copper peptide, applied to clean skin in a few drops. The Dosed Collective GHK-Cu serums are cosmetic products for external use.
- What is the difference between a peptide serum and a regular serum?
- A peptide serum is built around specific peptides rather than a single general hydrator or exfoliant. In copper peptide skincare, the peptide is the headline ingredient and the rest of the formula — water, hyaluronic acid, glycerin — is there to carry it comfortably on the skin.
- How do you use a copper peptide serum?
- Apply three to four drops to clean, dry skin in the morning or evening, then pat gently until absorbed. Follow with your usual moisturiser. Patch test before first use and discontinue use if irritation occurs.
- What is SNAP-8 and why pair it with GHK-Cu?
- SNAP-8 (acetyl octapeptide-3) is a peptide used in cosmetic formulas focused on the appearance of expression lines. Pairing it with GHK-Cu gives a single serum two peptide ingredients, which is why it sits at the more advanced end of the collection.
- Are these serums cosmetics or supplements?
- They are cosmetic topical products for external use. They are not dietary supplements and are not intended to diagnose, treat, cure, or prevent any disease. Oral dissolving strips are a separate category and are marketed as dietary supplements.
