Proactiv's Skin Purifying Mask is a sulfur (6%) face mask that heals breakouts, clears pores, reduces oil, and prevents new pimples from forming. It’s made with kaolin clay, a natural mineral that acts like a magnet and draws pore-clogging impurities out of the skin.A creamy, soothing formula, Skin Purifying Mask treats acne while reducing redness and helping with irritation. It also works hard to deep clean skin, which helps shrink the appearance of pores. Use it as a 10-minute mask or an overnight spot treatment. This acne-fighting face mask also features vitamin E to soothe and protect, vitamin F complex to help skin retain moisture, and tea tree oil for its antiseptic and cleansing properties.How To Use:As a mask: Apply to dampened skin, leave on for 10 minutes and rinse off with warm water.
