"Eye masks are used infrequently compared to a cream," Dr. Gross tells Byrdie. That said, the frequency of use really depends on the formula, as well as your skin type and specific concern.  Some eye masks will yield results with weekly use, whereas others may be more effective if used two or three times a week. "Also, I would advise to only try one new mask or product at a time in case of an irritation or allergy," says Dr. Wolinsky.
