This mineral sunscreen leaves a soft finish. It isn't as moisturizing as Round Lab's regular/chemical Birch Juice Moisturizing Sun Cream, takes longer to settle in and leaves a slight white cast, as it often is with mineral sunscreens. It also doesn't wash off as easily as the other version, and reapplication isn't as smooth.
