keraGEN-IV® – The keratin technology that reactivates your collagen
Bioactive functional keratin: −43.1% hair loss in 60 days and +10.1% skin elasticity.

What is keraGEN-IV®
Enhance your hair, skin and nails with a unique nutraceutical innovation.
keraGEN-IV® is a pure, bioactive form of functional keratin, designed to work in synergy with dietary collagen. While collagen provides the building blocks, keraGEN-IV® acts as a smart catalyst: it stimulates the production of the right types of collagen — especially collagens IV and VII, essential for smooth skin, strong hair and resilient nails.
Visible beauty, proven science
The proven benefits of keraGEN-IV®:
- −43.1% hair loss in just 60 days
- +10.1% skin elasticity
- −12.5% transepidermal water loss (TEWL)
Clinically tested in a randomised, double-blind, placebo-controlled study, certified by an independent laboratory in France (Laboratoire BIO-EC).
Mechanisms of action
- Strengthens hair follicles: increases collagen IV expression in the bulb, improving hair anchoring and limiting loss linked to stress, colouring or menopause.
- Reduces wrinkles: stimulates collagen IV and VII production, rebuilding the dermo-epidermal junction, key to firm skin.
- Supports healthy nail growth: thanks to its exceptional content of sulphur amino acids (cystine), for stronger, less brittle nails.
