People have used clay masks for thousands of years to help clear pores, slough off the dead outer layer of skin and soothe and calm inflammation. It's really very simple to make at home and you can get the clay at a natural foods store.
In this recipe, the lactic acid in the milk (alpha hydroxy acid) helps slough off dead skin cells, the clay helps to clear out your pores and the honey helps to soothe.
3 - 4 tablespoons whole milk
2 tablespoons clay (Green or French Clay and White Kaolin are good choices)
1 teaspoon honey
4 drops essential oils (optional)
Mix the ingredients together adding more milk or water if the mask is too dry. Apply evenly to face (and neck if you want) avoiding the eye area. Leave on for 15 minutes or until dry and rinse off with warm water. I usually wash my face following a mask just to ensure that I've removed all of it.
Now, my favorite facial mask is an aspirin scrub that I use in conjunction with a clay mask. This works well only if you have oily skin that is not sensitive. Essentially, the salicylic acid in the aspirin works like any commercial product in helping clear out your pores.
What I end up doing is dissolving about 3 uncoated aspirins in a very small amount of water and mixing it into the clay mask. It acts as a scrub when you put on the mask. Leave it on for the same amount of time and there you have it! Clear skin.
