What it does

Peak Glow benefits.

Mechanism

How it works.

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.

The Evidence

Published research on the compound.

These findings describe peer-reviewed research on GHK-Cu · Glutathione · Vitamin C — the active(s) in Peak Glow. Claims are about the compound, not our formulation.

Pickart et al. · Biomed Research Int 2015

Reviews GHK-Cu as a modulator of multiple skin-regeneration pathways, upregulating collagen and elastin.

PMID 26236730.

Stanescu et al. · Molecules 2026

Systematic review of glutathione in skin ageing — redox modulation and collagen protection.

PMID 41900080.

Mechanisms are well-established; large injectable human RCTs are limited. Studied models, not "clinically proven."
