Investigation and Characterisation of Cosmetic Ingredients Based on Probiotic Bacteria Ferment Lysate in Combination with Alginite Mineral

The most common fermented cosmetic ingredients are fermented rice, soy, green tea, fruits, and vegetables. Our laboratory is investigating a mineral rock called alginite, which has many benefits in other fields such as agriculture, O/W demulsification, and cosmetics, such as a facemask. It has been proven that alginite with LAB (Lactic acid producing bacteria) probiotics is beneficial for health and can increase biomass production. However, biomass with alginite has never been investigated for cosmetic purposes, such as for hydrating, antioxidant effects, and skin whitening properties. In our research, the alginite boosted the LAB biomass hydrating effect ten times higher and the antioxidant effect ten times higher (in the case of lactobacillus rhamnosus), but had no effect on mushroom tyrosinase inhibition, i.e. pigment formation.
