Try It: Clay Masks
What it is: Clay masks have been around for a while, but a growing number offer mud from places as far-flung as Morocco and the moors of Ireland, believed to be richer and contain a higher concentration of skin-rejuvenating chemicals.
How it works: The properties of clay act like a magnet with your skin, drawing out oil and dirt that are clogging your pores.
Bottom line: “Clay masks are good for reducing oil on the skin,” says Dr. Chang. “But they are less effective for decreasing the appearance of pores. For that, you’ll want a mask that contains salicylic or glycolic acid.” Also, wearing a mask requires a 10- to 15-minute time commitment.
