Dermatologist Note
Birch juice (Betula alba) is rich in xylitol, a natural sugar alcohol with humectant and prebiotic properties. Research suggests xylitol can selectively inhibit skin pathogens like Staphylococcus aureus (implicated in eczema flares) while supporting beneficial bacteria. The anti-inflammatory properties of birch polyphenols are also documented in dermatological literature.
Based on published clinical literature and dermatological research.
