Cruelty-free from formulation to shelf. Our products are never tested on animals — because great skincare shouldn't come at a cost to them.
In-House Formulation
Every batch is developed by our own formulation team. Full concentration disclosure on every active — no proprietary blend shortcuts.
Why choose RESKN?
GHK-Cu is a naturally occurring copper tripeptide your body already produces — but levels drop to 60% between age 20 and 60. Our serum restores what time takes away.
1.2% GHK-Cu at clinical concentration signals your cells to ramp up collagen production, accelerate repair, and restore youthful firmness.
Copper Tripeptide-1 activates your skin's own collagen and elastin production, rebuilding structure that fillers can only fake.
Niacinamide and Multi-Weight Hyaluronic Acid work together to brighten, plump, and deliver that lit-from-within quality.
Madecassoside from Centella Asiatica is anti-inflammatory, accelerates wound healing, and supports GHK-Cu's repair pathway with zero irritation.
At $89 AUD, get declared-concentration copper peptides formulated in-house by Australian chemists — no clinic visits required.

Frequently Asked Questions
GHK-Cu (copper tripeptide-1) is a naturally occurring peptide in your body that signals skin cells to regenerate. It stimulates collagen and elastin production, reduces inflammation, and accelerates wound healing. Our serum delivers it at 1.2% clinical concentration.
Most users notice calmer, less reactive skin within the first week. Texture improvements and smoother scarring typically appear around weeks 2–4. Visible firmness and collagen rebuilding become apparent from weeks 5–8 with consistent use.
Do not layer with Vitamin C in the same routine — copper can degrade ascorbic acid. Use Vitamin C in the AM and GHK-Cu in the PM, or alternate days. This is a pro tip that most brands won't tell you.
Yes! The natural blue tint is from Copper Tripeptide-1. It's characteristic of the molecule and does not stain skin. It actually indicates you're getting real, properly concentrated copper peptide.
GHK-Cu is inherently anti-inflammatory and well-tolerated by most skin types including sensitive and rosacea-prone skin. Our formula includes Madecassoside and Panthenol for additional soothing. As with any active, we recommend a patch test first.
