As wearing a mask can cause the skin to sweat and pores to become blocked with sebum and bacteria, double cleansing morning and night is essential for keeping the pores clear of irritating toxins, affirms Abi Oleck, celebrity facialist and skin expert at BeauSkin London

“Start with an oil-based cleanser to remove makeup and/or a gentle cleanser to remove the daily pollution on your skin,” she says. “Follow with a treatment cleanser – a gel cleanser works more deeply and can also be left on the skin as a mask to brighten and smooth.”

Oleck also advises using a cleanser with a low pH of 3.5 that is made with either L-lactic or a plant-derived Salicylic Acid. CosMedix’s Clarify Salicylic Foaming Cleanser fits that bill as it unblocks pores and is suitable for sensitive and dry skin as well.

“The Foreo sonic cleansing brush made with soft silicone is [also] excellent for giving a deep cleanse and enhances the health of the barrier that protects against UV damage,” she adds.
