To mix, use either a wooden, plastic or glass bowl & spoon. Use 2 parts mask to 1 part liquid. Use more liquid for a thinner mask and less liquid for a thicker mask. Your powdered mask is designed for immediate use after hydration. The liquid you use is only limited by your imagination (within safe guidelines). Try hydrating your mask with yogurt, kefir, soy milk, almond milk, your favorite oil, honey, hydrosol, distillate water or any liquid that is beneficial to the skin. Leave on for 10-15 minutes. Wash off with warm water using washcloth. Follow with either Bilberry or White Willow Toner.
