As a highly-focused effort to maintain healthy-looking skin, this pro-repair, pro-collagen serum offers a novel approach to target all visible signs of skin aging indirectly. This indirect approach departs from the traditional thinking of addressing visible aspects of skin aging individually and instead forms a foundation to respect skin health.
 
Previous generations of Copper amino isolate contained 2% of pure GHK peptide, of which 1% branched with copper ions upon mixing, forming 1% freshly-assembled, pro-repair GHK-Cu (copper peptides) and leaving 1% free-form, pro-collagen GHK peptide, for a final ratio of 1:1. The new formula omits mixing, instead containing 1% concentration by weight of pre-assembled and fully stable GHK-Cu, alongside 1% GHK peptide.
