I bought the clay from Amazon and organic Apple Cider vinegar is sold in most grocery stores. I use a large stainless tablespoon to mix the ingredients.
Scoop some clay onto spoon and add some apple cider vinegar about 1:1 (the vinegar has healthy probiotics and the acidity exfoliates). It will start to bubble. Mix the solution well with finger or cotton swab. Then apply to face, avoiding eyes. Let dry about 5 minute-10 minutes depending on how thick you make the mask. You will feel your skin tightening.
I remove mask by gently wiping off some of it with either a hypoallergenic natural facial towelette or a moistened tissue before rinsing off with water. This is to prevent the clay from accumulating in the drain and risk clogging up the sink.
Voila- nice smooth skin and smaller pores. Of course don’t do this if your skin is sensitive.
