Michelle L.
I've had copper peptide IV drips at my cosmetic clinic for years at $350 a session. This serum delivers the same skin-firming effect I notice post-treatment. Genuinely shocked.
Priya S.
I have acne scarring on my cheeks that's been there for a decade. After 6 weeks on this, the texture has smoothed visibly. My aesthetician asked what I'd changed.
Karen W.
Rosacea-prone and I can count on one hand the actives I can tolerate. This is one of them. Skin is calmer, more even, and the firmness after a month is undeniable.
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.
- Fine Lines & Loss of Firmness – Collagen production declines with age, leading to sagging skin, wrinkles, and loss of facial volume.
- Acne Scars & Uneven Texture – Post-inflammatory marks and pitted scars resist most topicals, leaving skin rough and uneven.
- Dullness & Lack of Radiance – Slowed cell turnover and oxidative stress can leave skin looking tired, sallow, and lifeless.
- Redness & Sensitivity – A compromised skin barrier leads to inflammation, irritation, and reactive skin conditions.
- Expensive Clinic Treatments – Copper peptide IV drips and clinical treatments cost $150–$400 per session and require ongoing visits.
- Visibly firms and lifts sagging skin – 1.2% GHK-Cu at clinical concentration signals your cells to ramp up collagen production, accelerate repair, and restore youthful firmness.
- Fades acne scars and evens skin texture – Copper Tripeptide-1 activates your skin's own collagen and elastin production, rebuilding structure that fillers can only fake.
- Restores your natural lit-from-within glow – Niacinamide and Multi-Weight Hyaluronic Acid work together to brighten, plump, and deliver that lit-from-within quality.
- Calms redness and sensitivity on contact – Madecassoside from Centella Asiatica is anti-inflammatory, accelerates wound healing, and supports GHK-Cu's repair pathway with zero irritation.
- Clinic-grade results for just $2.96/day – At $89 AUD, get declared-concentration copper peptides formulated in-house by Australian chemists — no clinic visits required.

My skin has this lit-from-within quality now that I can only describe as expensive. Three weeks in and people keep asking if I've been on holiday.
Sophie R.
Adelaide
The natural blue tint had me worried at first but it absorbs beautifully. My fine lines around my eyes are visibly softer after just two weeks.
James T.
Gold Coast
Started using this after reading about copper peptides for post-procedure recovery. My skin texture has never been this smooth — and I haven't even had a treatment.
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.
