Cambrian Blue Clay Spot Treatment Mask is formulated to reduce existing blemishes while deeply detoxifying the skin. It is best to follow with a moisturizer. For oily skin types we suggest following a blue clay treatment with our Blue Tansy Facial Oil. Put simply, clay is a topical detoxifying, rejuvenating, and strengthening agent. It extracts toxins and impurities from the skin while delivering much needed minerals to maintain smooth and fresh skin. No fillers – only pure skin softening botanicals and clay in this mask.
