The ingredient narratives reshaping clean beauty.
Collagen
aka hydrolyzed collagen · soluble collagen · marine collagen peptides
Ubiquitous anti-ageing active in K-beauty PDRN serums. The topical collagen question — whether hydrolysed fragments stimulate endogenous collagen — remains scientifically contested.
- Humectant function via water-binding peptides
- Film-forming on skin surface
- May stimulate endogenous collagen synthesis via receptor interaction at low MW
- Moisturising and skin-feel improvement
- Marine-sourced variants popular in K-beauty
- Anti-ageing serums
- PDRN combination formulas
- Sheet masks
- Spray mist formulations
- Firming body lotions
MW dictates penetration depth — <3 kDa fragments may penetrate into viable epidermis. Standard hydrolysed collagen (10–100 kDa) functions at skin surface.
Intact collagen cannot penetrate the skin barrier. Marketing routinely overstates topical collagen's relationship to dermal collagen.
Widely embraced in clean beauty and K-beauty. Consumer perception of efficacy significantly exceeds scientific evidence for topical application.
