As amazing as it may seem, the kombucha discs can be used in external applications, as an ointment.
Thanks to your kombucha culture, as soon as you have a new disc that grew up on the surface, you can reduce it in cream, by using a kitchen mixer: the cream thus obtained is to apply on the face, for a duration of 20 minutes. Take advantage of this time to lie down and relax.
After 20 minutes, simply rinse the cream with hot water.
Thanks to its high concentration of active yeasts, the resulting cream is also an excellent moisturizer!
