What is Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++)?
It is Round Lab's sunscreen stick, sold as the Korean-market formula rather than a version reformulated for US retail.

Who is Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++) suited for?
It suits shoppers targeting uneven tone and dark spots, and it is built for the final sun-care step rather than a different stage of the routine. Patch test first if you are new to Round Lab or to this formula.
Is Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++) the authentic Korean-market formula?
Yes. We source Round Lab's Korean-market formula rather than a version reformulated for US shelves. What ships is the listed unit sold on Korean shelves, with the Korean barcode and batch code intact on the box.
What does Round Lab make besides Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++)?
Round Lab formulates around a small set of single-origin naturals (pine, birch sap, soybean, camellia, Dokdo island seawater) rather than chasing trend ingredients, and builds most of its lines around one hero botanical at a time. This sunscreen stick sits alongside the rest of Round Lab's Korean-market catalog on our site, all sourced the same way.

How it works
Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++) is Round Lab's sunscreen stick, sitting at the final sun-care step in a layered Korean routine. Diethylamino Hydroxybenzoyl Hexyl Benzoate is a chemical UV filter used for broader-spectrum coverage in Korean sunscreen formulas. Ethylhexyl Triazone is a chemical UV filter common in Korean sunscreen formulas. Niacinamide is the brightening, barrier-supporting workhorse behind most Korean tone-evening formulas, and it layers easily under sunscreen and makeup. As a Korean-market sunscreen, the filter system and finish are formulated to Korean cosmetic standards rather than the US OTC monograph, which is exactly why shoppers look for it by name instead of settling for a US-shelf substitute. Round Lab sells Birch Juice Moisturizing Sun Stick 19g (SPF 50+ PA++++) as one entry in a wider catalog, and this 19.0g is sized the way Korean shoppers actually buy it rather than a US-market repack.
Worth knowing
- Patch test on the inner arm before first use on the face, especially if trying this brand or formula for the first time.
- Store away from direct sunlight and heat so the formula and any actives inside stay stable through its shelf life.
