“The most benefit is gained from the minerals in a clay mask while it is still damp, long before it dries.”
— SHARON MCGLINCHEY, Australian facialist and MV Organic Skincare founder. (Emma Watson and Maggie Gyllenhaal are fans.) As the mask contracts, you’ll get a gentle exfoliation, says McGlinchey—but remove it before it dries completely or it can start drawing moisture from the skin (something you definitely don’t want). Try: MV Organic Skincare Signature Mineral Mask ($63), Laline Face Mud Mask ($19.95) or Aztec Secret Indian Healing Clay ($39).
