How it works in skincare

In skincare, kombucha works by delivering a cocktail of naturally occurring organic acids, B vitamins and polyphenols that help to gently exfoliate, balance skin pH and protect against environmental stressors. The fermentation process creates bioactive compounds that support the skin’s natural microbiome, promoting a smoother, more even complexion and enhancing overall skin radiance without irritation.
