ROUND LAB Birch Juice Moisturizing UVLOCK SPF 45
by Round Lab · skin_care
Editor's Take
Strong UV protection and moisturizer-level comfort earn the shelf space, but the birch story cannot greenwash a petrochemical-heavy base.
Four-pillar formula scores
- Efficacy: 8.1 / 10
- Modern Tech: 7.2 / 10
- Clean Beauty: 4.0 / 10
- Sustainability: 1.3 / 10
The Verdict
Round Lab built a capable daily sunscreen around Avobenzone, Homosalate, and Octisalate, with added stabilization for more dependable broad-spectrum coverage. Birch juice, Niacinamide, Sodium Hyaluronate, and Allantoin give the formula credible hydration and barrier support rather than decorative skincare claims. The trade-off is poor sustainability alignment, driven by petrochemical solvents, synthetic polymers, and silicone. Worth it for comfortable daily protection, not for a strict clean or green routine.
