Kombucha ferment supplies the polyphenols of the tea it was brewed from together with the organic acids, sugars and cellulose fragments that fermentation generates. Topically the acids condition the surface slightly and the polyphenols contribute antioxidant activity. What no one can tell you is whether the fermentation adds anything beyond what green tea extract and a humectant would deliver, because that comparison has not been done properly. The culture also produces cellulose, the same material bio-cellulose sheet masks are grown from — a considerably more literal use of the ferment than the essence version.
