THE SCIENCE
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper peptide that functions as a biological signaling molecule. In skincare, it is recognized for supporting the skin's natural renewal process and helping maintain the appearance of healthy collagen and elastin, two essential components that contribute to skin firmness, resilience, and smoothness.
Its water-based structure allows for rapid absorption, making it an ideal first treatment step after cleansing and toning.
HOW TO USE
Apply 2–4 drops to clean skin after toner and before oils, moisturizers, and sunscreen.
For enhanced application, COPPER•K™ may be paired with a cosmetic microneedling device according to the manufacturer's instructions. Apply after gentle microneedling, then continue with the remainder of your skincare routine.
Finish with your preferred moisturizer and broad-spectrum SPF during the daytime.
STORAGE
Store in a cool, dry place away from direct sunlight to help preserve formula stability and performance.
