As for the frequency of your mask obsession, you may want to limit masking to once or twice a week for normal skin, or even less for those with sensitive skin. "Think of masks as a way to boost addressing a particular concern, like using something hydrating once or twice weekly when the skin dryness of Winter kicks in," recommends Hirsch.
You can monitor your skin's reaction to a mask, noting dryness, flaking, and redness, and adjust your regimen and frequency accordingly. "At home, I recommend everyone do a retinol mask at least once or twice a month to help get rid of acne and improve blemishes and pigmentation," recommends Emer. "And at least twice a week, use something that has pumpkin, papaya, or charcoal for exfoliating." Our favorite splurge-worthy retinol mask is Shiseido Benefiance Pure Retinol Intensive Revitalizing Face Mask($65).
