  • Standard Hydrolysed Collagen
  • 5–10 kDa average
  • None
  • None or incidental
  • Minimal measurable change in dermal elasticity; plasma hydroxyproline increase of 8–15%
  • Inefficient. Most peptides degraded before absorption; lacks cofactors for collagen cross-linking
  • Type I/III Blend (Low MW)
  • ≤3 kDa, 60%+ under 2 kDa
  • 500mg ascorbic acid co-dosed
  • 5–7% improvement in skin elasticity (Journal of Cosmetic Dermatology, 2023); 10–12% reduction in fine lines
  • Effective for collagen synthesis but limited dermal remodelling without copper cofactor
  • Full Glow Stack (Optimised)
  • ≤2 kDa dipeptides/tripeptides
  • 1–3mg GHK-Cu (evening dose)
  • 500mg ascorbic acid (morning, with peptides)
  • 7.2% elasticity improvement, 13% wrinkle depth reduction (Nutrients, 2023); increased fibroblast density on biopsy
  • Maximises both synthesis and cross-linking; sequenced dosing prevents oxidative degradation
  • Topical-Only Protocols
  • N/A (topical peptides 1–5 kDa)
  • 2% GHK-Cu serum
  • Topical ascorbic acid 10–20%
  • Localised improvement in photoaged areas; limited systemic collagen markers
  • Effective for targeted treatment but does not address systemic collagen loss; absorption limited to 1–2mm depth
