"The type of mask base depends on your skin oiliness," notes Jason Emer, cosmetic dermatologist and body contouring specialist in Beverly Hills. "Clay is best for those with thicker skin and a lot of oil, whereas jelly or biocellulose bases are good for those with sensitive skin who need hydration," he adds. If you're experiencing extra shine as a result of excess sebum production, you'll want to look for masks with clay, charcoal, or kaolin, which absorb oils and help detoxify pores. One example we love is the Origins Clear Improvement Charcoal Mask ($17).
Expert tip: you can (and should!) mix organic aloe vera into your mask before applying. "Clay masks can severely dehydrate the skin, causing rebound oil production, which can result in more breakouts for people suffering from acne," explains celebrity aesthetician Candace Marino. "Mixing aloe into your clay masks will not only hydrate the skin but will help reduce inflammation and redness as well as kill bacteria. This also improves the texture of the mask and makes it much easier to remove."
