Really lovely feel- takes a minute to absorb and the white to go away. Only sunscreen that doesn’t cause breakouts or irritate my sensitive skin.

I have very oily skin, and I’ve tried many sunscreens, but this one is my favorite so far. As a tan girl, I was a little worried at first because when I applied it, there was a slight white cast. However, it disappeared quickly and blended beautifully into my skin. It leaves my face smooth, comfortable, and not greasy at all. It feels lightweight, sits well on the skin, and doesn’t make me look shiny or heavy throughout the day. I also love how gentle it feels—no irritation for my sensitive, oily skin. If you struggle with oily skin and want a sunscreen that looks good after application, this one is definitely worth trying.

La textura del bloqueador es agradable, he sentido que da uniformidad al tono de la piel y no hace efecto de borrador, no tiene olor y tiene una sensación refrescante. Me ha gustado mucho!

Update: Al principio no había valorado que buen protector solar es este. Pero la realidad es que es el mejor protector solar mineral, honestamente. Sí lo recomiendo.

This sunscreen has quickly become a favorite in my daily routine. It offers broad-spectrum SPF 50+ protection with mineral zinc oxide, making it perfect for sensitive skin. What I love most is how lightweight and non-greasy it feels—no white cast, no stickiness, and it layers beautifully under makeup. The birch juice in the formula is incredibly soothing and hydrating, which helps calm any redness or irritation. It also does a great job at controlling oil and sebum throughout the day, leaving my skin balanced and fresh. Another huge plus: it’s reef-safe and ocean-friendly, so I can feel good about using it both daily and on beach days. 🌿☀️ If you’re looking for a gentle, effective, and eco-conscious sunscreen, this one from ROUND LAB is a fantastic choice. My skin loves it—and so do I!
