When NBC Select set out to find the best face sunscreen on the market, their editors didn’t just swatch a few formulas on the back of their hands. Over six months, they put 110 different SPFs through lab testing and real-life wear trials, measuring UVA/UVB protection, texture, finish, and performance on a spectrum of skin tones.
When the final scores rolled in, Round Lab Birch Moisturizing Sunscreen topped the entire list—beating out luxury icons and drug-store classics alike. Here’s a closer look at how we earned that gold medal and why skin-care enthusiasts (and dermatologists) are raving about Birch Sap sun care.
How the NBC Select Test Worked
- 110 formulas tested across chemical, mineral, and hybrid categories.
- Lab equipment measured SPF accuracy and UVA protection, while editors scored finish, white cast, pilling, and wear under makeup.
- Dermatologist-led panel weighed in on ingredient safety and photo-stability.
“Hydrating texture, non-greasy finish, and glowing absorption across skin tones without any white cast… the Birch Juice Sunscreen is as close to perfect as a face sunscreen can get.” — Editor Rodriguez, NBC Select
