What it does
Mechanism
GHK-Cu
A copper tripeptide that upregulates collagen, elastin and glycosaminoglycan synthesis in dermal fibroblasts.
Glutathione
The body's master antioxidant — neutralises the free radicals from UV and pollution that break down collagen cross-links. Accounts for most of the blend's mass.
Vitamin C
Essential cofactor for the enzymes that hydroxylate collagen precursors — without it, collagen can't form properly.
