Birch Juice Moisturizing Sunscreen — Reddit Reviews

Updated August 19, 2026
Moisturizing SPF 45 chemical sunscreen with birch juice and niacinamide; dewy finish.
What the community says
This chemical SPF 45 sunscreen features hydrating birch sap and niacinamide, ideal for dry, sensitive skin. Loved for its lightweight, lotion-like texture and gentle feel, though it can sting eyes and feel greasy on oily skin. Not water-resistant, so frequent reapplication is needed.
