Round Lab Birch Juice Moisturizing Sun Cream SPF50+ PA++++
The Korea/Olive-Young-Global version of Round Lab's Birch Juice Moisturizing Sun Cream is SPF50+ PA++++ and uses four newer-generation organic UV filters not approved by the US FDA. A separately named US-retail product, "Birch Juice Moisturizing UV Lock SPF45," sold at Amazon/Target/Ulta/Olive Young US, is a distinct reformulation using FDA-monograph filters (avobenzone, homosalate, octisalate) at a lower SPF rating.

| Korea vs export | Confirmed, well-documented reformulation. Korea's "자작나무 수분 선크림" (and the Olive Young Global listing of the same SPF50+ PA++++ product, which ships the Korean formula worldwide) uses four filters not FDA-approved — Uvinul A Plus, Uvinul T150, Tinosorb M, and Uvasorb HEB — confirmed by extracting the KR listing's own INCI text. By contrast, the standalone US-retail product actually named "UV Lock SPF45" (sold on Amazon/Target/Ulta, and separately listed on Olive Young US) uses only FDA-monograph filters — Avobenzone 2.7%, Homosalate 13.5%, Octisalate 4.5% — per Target's own product listing, and is rated SPF45 (not SPF50+) with no PA rating shown. This is a genuine two-SKU situation: "Birch Juice Moisturizing Sun Cream SPF50+ PA++++" (Korea formula, also sold on Olive Young Global) and "Birch Juice Moisturizing UV Lock SPF45" (US-specific reformulation) are not the same product. |
