ROUND LAB Birch Juice Moisturizing UVLOCK SPF 45
by Round Lab · skin_care
Editor's Take
Birch juice leads the hydration, Avobenzone leads the UVA defense, and a photostability system keeps both from degrading in sunlight.
Four-pillar formula scores
- Efficacy: 8.1 / 10
- Modern Tech: 7.2 / 10
- Clean Beauty: 4.0 / 10
- Sustainability: 1.3 / 10
The Verdict
This is a modern sunscreen that delivers strong efficacy (8.1) by pairing regulated chemical filters with a genuinely hydrating base. The birch sap and Niacinamide aren't filler , they're doing real barrier work while the photostabilizers keep the Avobenzone from breaking down. The clean score sits at 4.0 due to the chemical filters and synthetic polymer base, which is the trade you make for reliable broad-spectrum protection at this texture. Worth it if you want SPF 45 that actually moisturizes, not if you're shopping strictly clean.
