ROUND LAB Birch Juice Moisturizing UV Lock SPF 45 Sunscreen 1+1 (2-Pack), Lightweight Hydrating Essence, No White Cast

ROUND LAB Birch Juice Moisturizing UV LOCK SPF 45 1+1 is a lightweight, hydrating broad-spectrum sunscreen sold as a two-pack that protects skin from UVA/UVB while blending without a white cast.

This 1+1 (two-pack) version of ROUND LAB's Birch Juice Moisturizing UV LOCK brings the brand’s signature birch-derived hydration together with an SPF 45, OTC-registered formula tuned for daily face use. The texture reads more like a hydrating essence than a traditional cream, absorbing quickly and sitting smoothly under makeup. It’s designed to minimize pore-clogging and white cast while offering reliable broad-spectrum protection for everyday outdoor exposure.

How does this sunscreen feel on the skin?

The formula is an essence-like, non-greasy texture that leaves a natural, barely-there finish. It absorbs quickly and creates a breathable protective layer without heavy residue, so makeup applies evenly over it.

• Essence texture: lightweight, serum-like application.
• No white cast: formulated to blend on a wide range of skin tones.
• Non-greasy: comfortable for all-day wear, even in humid conditions.
