Why Choose GHK-Cu?
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that binds copper. In aesthetic skincare, it’s used to support the look of healthy collagen, elasticity, and barrier comfort while adding a subtle antioxidant/soothing effect. Many patients like it as a gentle, cosmetically elegant option.
“After 8 weeks, my skin feels calmer and makeup sits better—especially around fine lines.”
Patch Test & Routine Tips
- Apply a small amount behind the ear or inner forearm.
- Wait 24–48 hours. Mild warmth is possible; stop if rash, swelling, or severe itch occurs.
- If clear, begin regular use per your plan.
- Separate from strong acids/retinoids if irritation occurs (e.g., GHK-Cu AM, actives PM).
- Avoid immediate application before contact with light-colored fabrics.
- Do not share products; keep away from children and pets.
