I’m really impressed with this sunscreen! Great consistency, lightweight, and easy to apply without feeling greasy or heavy on the skin. It doesn’t leave a white cast, which can be hard to find with mineral formulas. I also love that it’s made with natural ingredients, which makes me feel good about using it. Definitely will buy again!
