GHK-Cu Advanced Peptide Serum
GHK-Cu isn't new — it's one of the most studied peptides in modern skincare. What's rare is finding it at a concentration that actually works.
NXTGEN's GHK-Cu Advanced Peptide Serum delivers Copper Tripeptide-1 in a lightweight, fast-absorbing base designed for daily use. No fragrance. No fillers. Just a clean, effective formula built around an ingredient with decades of research behind it.
What GHK-Cu does
GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper peptide complex. In cosmetic formulations, it's used to support the appearance of:
- Firmer, more resilient skin texture
- Improved skin hydration and barrier function
- Smoother-looking skin and reduced appearance of expression lines
- Overall skin clarity and condition
It works alongside a supporting cast of proven cosmetic ingredients: Niacinamide for tone and barrier support, Sodium Hyaluronate for deep hydration, Panthenol for soothing and repair, and Squalane for lightweight moisture lock.

Frequently asked questions
What does GHK-Cu actually do to skin?
GHK-Cu is a copper peptide that in cosmetic research has been shown to support skin firmness, barrier function, and overall skin quality. It's one of the most well-researched peptides used in skincare today.
Can I use this with other actives?
Yes. GHK-Cu pairs well with hyaluronic acid, niacinamide, and moisturisers. If you use vitamin C or strong acids, apply those first and follow with the serum.
How long before I see results?
Most users notice improved hydration and skin texture within 2–4 weeks of consistent daily use. Firming and appearance benefits typically develop over 6–8 weeks.
Is this the same as Botox or injectables?
No. This is a cosmetic topical serum. It supports the appearance of smoother skin but does not affect muscle movement or replicate injectable treatments.
Is it tested and safe?
