When you purchase a wet mask that's been blended with waters, aloe, glycerin, and other water based ingredients, it requires a preservative and if those masks contain clay, it requires an especially strong preservative because wet clay is one of mold's favorite foods. We formulate dry masks for several reasons: 1) They're as fresh as possible when they get to you, there's no chance of bacteria, yeast, or mold growing in your mask, and you don't have to use it in a super short span of time. 2) They're customizable! Depending on how your skin is feeling on any particular day, you can blend your mask with warm water, hydrosol, a brewed tea, or even a carrier oil or liquid cleanser. These masks are made to meet your skin where it's at. 3) We're big fans of whole plant skincare rather than extracts that only harness some of a plants' compounds. When you blend your mask with your chosen liquid, you're rehydrating a whole plant which your skin, as a part of nature as well, recognizes and knows what to do with because plants and your skin speak the same language. 4) When you purchase one of our masks, you're purchasing the pure, intentionally-sourced plants and clays. You're not paying for a bunch of fillers and water. Our masks are extremely potent, yet gentle enough for the most sensitive skin.
