How to NOT Ruin Your Skin During Flu Season

While each dermatologist we spoke with suggests different products to use while you're feeling icky, they all agree on one to avoid like the plague: exfoliator! "Most people don't have the energy to do this, but I would hold off [on exfoliators or scrubs] so as to not add more dryness," Dr. Gohara said.

Dr. Farber agreed: "Stick to a more gentle routine with a hydrating cleanser and cream moisturizer to repair cracked skin."

Alpha and beta hydroxacids, retinol, and microdermabrasion should also be avoided, noted Dr. Zeichner, because these "irritating skincare ingredients can make matters worse."
