Clinics charge hundreds for copper peptide injections. This is the daily alternative, now in your daily skincare routine. GHK-Cu tells your skin to act younger - rebuilding from the inside out.
While most serums stop at one or two peptides, this formula consists of SIX - built around Copper Tripeptide-1 (GHK-Cu), one of the most well-researched anti-ageing ingredients in skincare.
Together, these peptides take a multi-targeted approach to repair and renewal: stimulating collagen, restoring skin density, visibly softening expression lines, and rebuilding firmness over time.
GHK-Cu works beneath the surface - actively fading dark spots, hyperpigmentation, and acne scarring by normalising melanin production and replacing damaged cells with healthy ones. Glutathione amplifies this effect, inhibiting melanin production and neutralising the free radicals that cause uneven skin tone.
This formula also goes beyond peptides - FOUR forms of Hyaluronic Acid deliver hydration at every skin depth, while Ceramide NP reinforces the skin barrier to lock in moisture and keep skin resilient.
Fast-absorbing formula. Zero tackiness. Layers seamlessly under moisturiser.
Aqua, Butylene Glycol, Pentylene Glycol, Glycerin, Hydroxyethylpiperazine Ethane Sulfonic Acid, Sodium Polyacryloyldimethyl Taurate, 1,2-Hexanediol, Erythritol, Panthenol, Hydroxyacetophenone, Copper Tripeptide-1, Carnosine, Acetylated Sodium Hyaluronate, Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, Hydrolyzed Collagen, PPG-5-Ceteth-20, Acetyl Hexapeptide-8, Acetyl Octapeptide-3, Acetyl Heptapeptide-4, Acetyl Tetrapeptide-2, Palmitoyl Tripeptide-5, Glutathione, Ceramide NP.
Apply 2–3 drops to clean, dry skin morning and/or evening. Press gently into the face and neck. Follow with moisturiser. Suitable for all skin types, including sensitive. Pair with SPF during the day.
Use morning and/or evening for best results.
Avoid using this serum at the same time as:
- Strong acids (AHAs/BHAs) — ingredients like glycolic, lactic, or salicylic acid can destabilise copper peptides and reduce their effectiveness. Use acids on alternate evenings instead.
- Vitamin C (L-Ascorbic Acid) — can interact with copper peptides and counteract their benefits. If you use both, apply Vitamin C in the morning and this serum in the evening.
- Retinol/Retinoids — both are potent cell-renewal actives. Using them together can cause irritation and is generally unnecessary — they're better alternated.
The peptide complex — what's working and why
GHK-Cu is copper bonded to a peptide — and it's one of the most well-researched ingredients in modern skincare. Your skin naturally produces it, but levels drop significantly with age. It signals your skin to produce more collagen and elastin, helps repair damage, and fights the free radicals that speed up ageing. Think of it as your skin's own renovation crew, brought back in full force.
This peptide works by gently reducing the muscle signals that cause repetitive facial movements — the kind that form expression lines around the eyes, forehead, and mouth over time. It doesn't freeze anything; it just turns down the volume on those micro-contractions so lines form less deeply. Think of it as a preventative measure that gets more effective the longer you use it.
Every time you make a facial expression, your muscles contract — and repeated thousands of times over years, those contractions crease the skin into expression lines. Snap-8 reduces the intensity of those contractions without affecting natural movement, gradually softening existing lines and preventing new ones from forming. A needle-free alternative to the mechanism behind Botox, built into your daily routine.
This peptide encourages your skin to renew itself more efficiently — speeding up the natural cell turnover process that slows down as we get older. Over time the result is smoother texture, a more even tone, and skin that looks more refreshed. It works alongside the collagen-building actives in this formula to make sure new, healthy skin cells are consistently showing up.
As we age, the scaffolding that keeps skin firm — proteins like collagen IV and laminin — starts to break down. Acetyl Tetrapeptide-2 stimulates the production of these structural proteins, helping to maintain skin density and that lifted, firm feeling. It's the ingredient working quietly in the background to keep everything in place.
This peptide mimics one of your body's own collagen-triggering signals — specifically TGF-β, a growth factor that tells your skin to produce new collagen deep in the dermis. Think of it as sending the same message your body would naturally send, but from the outside in. It works in direct support of GHK-Cu, amplifying the overall collagen-building effect of the formula.
Other Key Ingredients
Most serums use one form of hyaluronic acid. This formula uses four, each a different size. The larger molecules sit on the skin's surface and plump it instantly. The medium ones absorb into the upper layers and hold moisture there throughout the day. The smallest penetrate deeper to hydrate from within. Together they give you the kind of hydration that doesn't wear off by midday.
Often called the master antioxidant, Glutathione works on two levels. First, it neutralises free radicals that cause oxidative stress and uneven skin tone. Second, it directly inhibits the enzyme responsible for melanin production — making it one of the most effective brightening ingredients available. It works in direct support of GHK-Cu's dark spot fading activity, amplifying the overall brightening effect of the formula.
Ceramides are the naturally occurring lipids that hold your skin cells together — forming the barrier that keeps moisture in and environmental stressors out. As we age, ceramide levels decline, leaving skin dry, sensitive, and prone to irritation. Ceramide NP replenishes this barrier, locking in everything the other actives are working to deliver and keeping skin resilient and comfortable.
Here's something most people don't know: sugar in the body can actually damage collagen fibres — it's a process called glycation, and it makes skin look dull, stiff, and aged over time. Carnosine blocks this process, protecting the collagen that the rest of the formula is working hard to build. It also neutralises free radicals, doubling as a classic antioxidant.
Panthenol — better known as provitamin B5 — is one of skincare's most trusted soothers. It reduces redness, repairs the skin barrier, and keeps skin soft and calm. Erythritol draws moisture into the skin and adds a mild antioxidant effect. These two make sure the formula feels gentle and comfortable on skin, even while the actives are doing intensive repair work underneath.
