So I have been searching for a clay mask for so long! I'm looking for one that really detoxifies and is suitable for oily, acne-prone skin. I really really loved the effects of Mask of Magnaminty from Lush and just finished up my mega pot yesterday however..I really wasn't a fan of the talc or parabens used in the product. So i'm looking for a dry (mix it yourself) mask or a premoistened mask that is paraben and formaldehyde free. Any ideas?
