Versatile Use: Designed to fit seamlessly into any skincare routine, the Glutathione Spray can be used at any step, whether as a toner, a setting spray, or a refreshing mist throughout the day, for immediate improvements in tone, texture, and elasticity
Compatible with: Hyaluronic acid (for hydration) Niacinamide (for barrier support and tone) Growth factors Peptides (like Matrixyl or Argireline) Use with caution: Vitamin C (especially L-ascorbic acid) may destabilize copper peptides if mixed directly Retinoids can cause irritation when layered with GHK-Cu unless used at separate times (e.g., retinoid at night, GHK-Cu in the morning) AHAs and BHAs can lower skin pH and potentially reduce the effectiveness of copper peptides Spacing out these ingredients or consulting with a provider for a personalized routine can maximize benefits and avoid conflicts
Another study with 41 women showed that GHK-Cu eye cream worked better than vitamin K cream or plain cream for making the eye area look younger
