Behind the shell

🥚

We haven't even introduced ourselves! 👋

In Brittany, in the heart of France's leading poultry basin, we aim to valorize the 40,000 tons of shells discarded each year to extract their treasure: the egg membrane.

It is from this membrane that we develop Reggenerate™, a bio-sourced, effective and clinically proven ingredient for health and beauty.

"Eggsplain it to me"

Quickly find answers to your questions

Reggenerate™ is effective at a low dose thanks to the natural synergy of its biomolecules (collagen types I, V, X, elastin, hyaluronic acid, GAGs...). Unlike a conventional hydrolyzed collagen, each component acts in a complementary manner, which increases bioavailability (≈85% versus 30–50% for other collagens). That's why only 300 mg is sufficient, with clinically proven efficacy.
