TetraGold®

TetraGold® is a bioactivated phytocomplex derived from the green microalga Tetraselmis suecica, developed through an innovative two-step biotechnological process to support skin hydration, sebum balance and barrier function.

Through enzymatic hydrolysis, bioactive molecules such as sugars, carotenoids and polyphenols are released from the nutrient-dense microalga. The extract is then fermented with the probiotic yeast Saccharomyces boulardii, enriching it with postbiotic metabolites and improving bioavailability, resulting in a multifunctional active for modern skincare, haircare and clean beauty formulations.
