Oil-Free Ultra-Moisturizing Lotion with Birch Sap — Reddit Reviews
by COSRX
Updated October 24, 2026
Birch sap lotion hydrates without grease, layers cleanly, and suits oily-combination skin.
What the community says
A lightweight birch-sap lotion built for daytime hydration, especially when heavier creams turn shiny or congested. It layers well under sunscreen and helps tretinoin routines, but the finish can turn sticky or oddly heavy, and birch-sensitive users should be cautious.
What this means for you
What people love
Watch out for
- Breakouts can be severe for some users
- Can turn sticky or heavy despite the gel-like texture
- Birch allergy cross-reactivity and occasional eye stinging are real complaints
