Research on human skin explants (cross-sections of intact human skin) has shown this ingredient can help reactive skin become less sensitive to environmental aggressors via strengthening its microbiome. Doing so encourages skin to visibly repair itself and begin looking healthier. Fermented probiotics have also been shown to help reduce the proliferation of harmful microorganisms on skin’s surface, potentially improving common, often uncomfortable skin concerns. As this is a probiotic-related ingredient, it is best to keep it away from both light and air exposure.
