TetraGold® is an innovative cosmetic active product obtained from advanced fermentation technology of the marine microalga Tetraselmis suecica. This technology allow to exalt the active ingredients of the microalgae, such as antioxidants, vitamins and minerals, and increase their bioavailability on the epidermis. 

The probiotic yeast Saccharomyces boulardii enriches the product with important beneficial metabolites that confer various biological and postbiotic activities. 

The result is a natural bioactivated phytocomplex that can effectively stimulate hyaluronic acid production, preserve it by inhibiting the enzyme hyaluronidase, and reduce epidermal sebum production. These characteristics make this valuable resource an important ingredient in the development of cosmetic products with regenerating and sebonormalizing properties.
