[RoundLab] White Birch Moisturizing Sun Cream (3-Piece Bundle)
Meet one of Korea's consistently best-selling sunscreen — and once you try it, you'll understand why.
The ROUND LAB White Birch Moisturizing Sunscreen SPF 50+ PA++++ has become a cult favorite across Korea, beloved by millions for one simple reason: it actually feels good to wear.
No thick, chalky layer. No white cast. No that-sunscreen-smell. Just a silky, essence-like texture that melts into your skin like a lightweight moisturizer — and you're out the door.
(And yes — we wear this one ourselves on outdoor workouts. It holds up beautifully, and most importantly, it doesn't bleed into your eyes. Anyone who's ever had to stop mid-exercise to wipe out stinging sunscreen knows exactly why that matters.)
If you've ever skipped SPF because it felt too heavy or left you looking ashy, this one's going to change the game for you. It glides on effortlessly, absorbs in seconds, and leaves your skin looking dewy and fresh — not coated. Layers perfectly under makeup too, without pilling or sliding off by noon.
Packed with White Birch Sap (자작나무), Glyceryl Glucoside, Allantoin, DPG, and Purslane Extract, it's doing serious skincare work while it protects. Your skin gets deep hydration, calming support against UV stress, and all-day comfort — not just sun protection.
Clinically tested for up to 10 hours of broad-spectrum SPF 50+ PA++++ coverage, it also shields against blue light from screens. Gentle enough for sensitive skin, with a Dermatest "Excellent" rating from Germany.
And because popularity shouldn't come at the planet's expense, the reef-conscious formula uses FSC-certified packaging and soy ink printing.
Korea already loves it. Your skin will too!
This is sold in a bundle of 3-pieces (50 ml each).
