ROUND LAB's birch sun cream fell about 37%

The lightweight, no-white-cast SPF50+ people rebuy on repeat is down to $13.72 at Stylevana, from the $21.90 I logged a week ago — a verified, in-stock listing, not a mystery third-party seller. Was $21.90; as of Aug 9, 2026.

Authenticity tip

How to buy ROUND LAB authentic: the Birch Juice and 1025 Dokdo lines get faked a lot on open marketplaces. Stick to Olive Young Global, the brand's own shop, or a seller I've checked — and glance at the batch code stamped on the crimp. My rule of thumb: if a sunscreen is selling for a third of everyone else's price, that's a red flag, not a deal. A genuine SPF almost never falls below about $10.
