Moisturizing yet lightweight serum-like texture with hyaluronic acid for hydration
What the community says
A moisturizing Korean sunscreen with birch sap, hyaluronic acid, and niacinamide that imparts a dewy finish and gentle hydration but can feel heavy and cause stinging or breakouts especially for oily, sensitive, or allergy-prone skin.
What this means for you
What people love
- Moisturizing yet lightweight serum-like texture with hyaluronic acid for hydration
- Generally no white cast and blends seamlessly with a natural dewy glow
- Gentle on sensitive skin and doesn’t sting eyes as much as many chemical sunscreens
Watch out for
- Can feel greasy and heavy especially on oily or combination skin, worsening shine through the day
- Reported to cause stinging around eyes and sometimes irritation or red flush, notably on compromised or sensitive skin
- Contains birch sap which may trigger eczema or allergic reactions and cause breakouts in some users
