by COSRX
Updated August 19, 2026
Chemical SPF 50 with hyaluronic acid for hydration and no white cast; pills under makeup.
What the community says
This sunscreen offers broad chemical UV protection with hydrating hyaluronic acid and no white cast. It’s good for oily and fungal acne-prone skin but dries out some users indoors. The formula often pills under makeup, requiring wait time or makeup adjustments.
