## How it works

Birch Juice Moisturizing UV Lock Sunscreen is Round Lab's sunscreen, sitting at the final sun-care step in a layered Korean routine. Butyl Methoxydibenzoylmethane is a chemical UV filter used for broader-spectrum coverage in Korean sunscreen formulas. Ethylhexyl Salicylate is a chemical UV filter common in Korean sunscreen formulas. Homosalate is a chemical UV filter used to stabilize a sunscreen's UVB coverage. 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 UV Lock Sunscreen as one entry in a wider catalog, and this 50.0ml is sized the way Korean shoppers actually buy it rather than a US-market repack.

## How to use

1. Use the Birch Juice Moisturizing UV Lock Sunscreen as the last step of the morning routine, over moisturizer and under makeup.
2. Apply it at the last stage of skincare routine 15 minutes before heading out. Gently massage for better absorption.
3. Nothing skincare goes over it. It is the last thing on in the morning, and it is never mixed into the moisturizer underneath it.
4. Every morning, and again through the day as the instruction on the pack directs. Do not stir it into your moisturizer to save a step.

### What does Round Lab make besides Birch Juice Moisturizing UV Lock Sunscreen?

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 sits alongside the rest of Round Lab's Korean-market catalog on our site, all sourced the same way.
