How to Choose Skincare Products Without Going Wrong

Endogenous collagen synthesis requires two types of signals. Signalling peptides (Matrixyl) tell fibroblasts that there's damaged collagen — and activate them to produce more. Vitamin C is the enzymatic cofactor that stabilises newly synthesised collagen. Without vitamin C, the collagen produced by peptides is structurally weak. The combination isn't marketing — it's biochemistry.

Complete Mechanism: Why Both Together Outperform Each Alone

Peptides (Matrixyl, GHK-Cu): bind to receptors in dermal fibroblasts and activate transcription of collagen type I, III and IV genes. Result: more collagen synthesised.
Vitamin C (cofactor of prolyl hydroxylase and lysyl hydroxylase): stabilises the collagen triple helix by adding hydroxyl bridges. Without vitamin C, synthesised collagen collapses. Result: stronger and more durable collagen.

Vitamin C deficit in the dermis — even subclinical — reduces peptide efficacy. The combination ensures that the synthesis signal (peptides) finds the structural conditions to produce functional collagen (vitamin C).

The Collagen Booster Serum combines both actives in a night formula — when skin has greater permeability and collagen synthesis is at its peak.

When Results Are Visible

  • 4–6 weeks: skin appears firmer, fine lines less pronounced
  • 8–12 weeks: measurable wrinkle reduction in peptide studies (Matrixyl)
  • 3–6 months: changes in skin density and elasticity

The Complete Collagen Protocol

Morning: Peptide + HA Anti-Ageing Serum → Vitamin C → SPF
Night: Collagen Booster Serum → Bakuchiol (alternating nights) → Ceramide Cream

To maximise: the Peptide Anti-Ageing Serum in the morning amplifies the Collagen Booster's work at night. The two serums cover the full 24-hour synthesis cycle.
