Why we stand behind it

Using cultivated yeast cells, our scientists created a breakthrough alternative to plant-derived collagens, which are not human-skin identical, and animal-derived collagens which are unethical and too large molecularly to penetrate the skin. Through this completely vegan, sustainable, biofermentation process, enzymes are released that distill molecules into micro-molecules, ensuring optimal absorption and efficacy.

Key ingredients

Ectoin: A potent, plant sourced amino acid that is crucial for collagen and elastin production. Ectoin helps protect skin from damaging UV rays and dehydration, while working to soothe and protect the skin barrier.

Wild Organic Turkey Tail Mushrooms: Rich in antioxidants, these mushrooms boost skin immunity and interrupt inflammation, supporting more resilient skin.

Organic Chaga Mushrooms: Slows the signs of skin aging while protecting against UV damage.
