Understand the Difference
Topical peptides (like GHK-Cu) are applied directly to skin.
Injectable grade and cosmetic grade formulations differ significantly in purity and concentration.
Ensure you're using a product designed for topical use.
Cleanse the Application Area
Cleanse skin thoroughly with a gentle, non-stripping cleanser.
Pat dry — do not apply to wet skin.
Avoid retinoids or acids immediately before application as they can affect absorption.
