There is a difference between “waterproof” and “water resistant.”  Usually waterproof makeup must be removed with oil or silicone based makeup remover. Our products are “water resistant,” which means they hold up well to sweat or even light rain.  No, you won’t need to reapply and you won’t “sweat it off.” All you need to do is dab or blot your face with a tissue or soft hand towel gently pressing the foundation into your skin. You can even use your hands to press the minerals into your skin. Yes, our products are water resistant but within reason. If you run a marathon wearing our products and cross the finish-line with a glamorous Valana Minerals™ glow, I want to know about it (I’ll pay you and put you in an ad)!
