I covered this a little in the post on acne treatment. The recipe is basically the same, however, like all my skin care recipes, you adapt the essential oil to what your needs are for your skin type.
2 parts water to 1 part clay (don't worry about making too much as you can store it in an air tight container and it will last several weeks)
1 tsp. of RAW honey
You simply put the mixture on your face the same way you would any mask and let it set for 15 minutes. Take a hot wet cloth and place it on your face to soften the mask once it is dry, then just wash it off. Be sure to follow with toner and moisturizer.
I would add more to this, but it would be repetitive. I discussed all of the benefits of the clay and honey on another post. . .
