Claims that it rebalances your skin's own microbial population are well beyond what has been shown. | Fermented sweet tea, filtered and put in an essence. It brings green tea polyphenols plus the acids and sugars fermentation produces, which is a plausible mix for surface conditioning. The evidence for kombucha specifically, as opposed to green tea or ferments in general, is slim. A pleasant ingredient with a good story attached. |
