Key Actives: VitalCopper™ Complex
Two of the most clinically studied peptide actives in skincare, at the concentrations the research is built on paired with barrier protection and anti-irritation support.
GHK-Cu (Copper Tripeptide-1) visibly reduces the appearance of wrinkles by up to 56%.
Matrixyl® 3000 reduced visible deep wrinkle appearance by up to 45% in 60 days. The barrier complex keeps both working at full dose, daily.
GHK-Cu
(Copper Tripeptide-1)
The copper peptide your skin already knows. Triggers the skin's own renewal response, so it looks visibly firmer, denser, and more renewed with consistent use.
Week 1–2Skin feels calmer, more hydrated and less reactive.
2
Week 3-8Skin appears smoother and more even as resilience builds.
3
Week 9-12Skin feels firmer and more refined as fine lines soften.
Week 1–2
Hydration & Calm
This is what skin feels like when it's not being disrupted. Calmer, more comfortable, less noise. The formula isn't fighting your skin. It's working with it from day one.
Week 3-8
Resilience & Clarity
Tone starts to settle, skin looks more even, less worked-over. The clarity people notice isn't a spike. It's the baseline catching up.
Week 9–12
Firmness & Renewal
Your skin doesn't respond to urgency. It responds to consistency. This is what sustained use looks like. Results that are structural, not surface-level, and don't disappear when you stop paying attention.
A copper peptide serum for face and neck — GHK-Cu 2% with Matrixyl® 3000, formulated to support the look of firmer, more even skin. One daily active instead of a multi-step routine.
Skin responds to consistency, not urgency. With VitalCopper, most people feel calmer, more hydrated skin in the first two weeks; tone and texture look more even through weeks 3–8; skin looks firmer and fine lines look softer through week 12.
Yes — with separate timing. Use VitalCopper at night and vitamin C in the morning, and alternate nights with retinoids and acids. Separating them keeps your baseline readable — not because they cancel each other out.
It’s built for skin that’s been over-treated or is running reactive. If your barrier is compromised, start at two to three nights a week and build up as tolerance holds, keeping the rest of your routine quiet while it settles.
1–3 pumps for face and neck, after cleansing and before moisturizer. Press it in; don’t overwork it. Start PM-first and build to morning and night as the routine holds. If your skin is sensitive or over-treated, stay at two to three nights a week until tolerance builds.
