How to use: in a non-metal container that has been water or a decoction of medicinal plants, pour enough clay to prepare the poultice or mask. Knead it with a spatula or wooden spoon, until a smooth paste is formed. As beauty mask, spread a thin layer over the desired area, letting it act for 10 to 15 minutes. Subsequently rinse with lukewarm water. Finally apply a moisturising cream. As a poultice, directly apply a thick layer on the skin and leave on for between one and three hours. Help a dry cloth or bandage to secure it. Retirla later and cleanse the skin with warm water. Finally apply a moisturizer.
