How it works
Three steps. Real chemistry.
- 1
Apply to Skin
Apply 2–3 drops and gently massage on cheeks, jawline, and under the chin. Absorbs in seconds, no grease, no stain.
- 2
Activate the Chemistry
The serum boosts collagen and elastin, and reduces inflammation, delivering firmer skin and sharper definition.
- 3
Let the Magic Happen
Daily use sharpens your jawline, sculpts cheeks, and fades soft bloating — revealing the chiseled structure underneath.
The Science
How GHK-Cu rebuilds your face
A naturally occurring copper tripeptide that signals your skin to repair, firm, and remodel — at a cellular level.
Molecular structure
Glycyl-L-Histidyl-L-Lysine bound to a copper ion — the active tripeptide complex.
1. Signals skin cells
GHK-Cu penetrates the dermis and binds to fibroblast receptors, switching genes from inflammation to repair mode.
2. Boosts collagen + elastin
Up to 70% more collagen production in 14 days — the structural protein that firms and tightens.
3. Sculpts and de-puffs
Reduces inflammatory cytokines linked to facial bloat. The result: tighter contours and a sharper jaw.
What's inside
Six ingredients. Zero filler.
Every drop is engineered. No fragrance, no parabens, no fluff — just actives that work.
- Distilled WaterUltra-pure base for maximum absorption.
- GHK-Cu (99%)The hero peptide. Firms, repairs, sculpts.
