Editor's Pick: The biggest concern with daily sunscreen is heavy, pore-clogging formulas. This sunscreen serum has a lightweight, essence-like texture that practically disappears upon application — no white cast or sticky residue. Infused with 73% moisturizing essence and birch sap, it keeps your skin hydrated while protecting it from the sun. It layers beautifully under makeup without pilling. With SPF50 protection, it's more than enough for daily commutes, and it's gentle enough for the eye area. A regular cleanser removes it easily — perfect for those who prefer a low-maintenance routine.
