14 Common Skin-Care Mistakes Dermatologists Say We're Guilty of Making

People often don't exfoliate at all or they do it too much but there is a sweet spot that you should aim for.

"Overexfoliation is one of the most common reasons for acne in my adult patients," said Dhaval Bhanusali, MD, FAAD, New York City-based board-certified dermatologist and founder of Hudson Dermatology & Laser Surgery. "Many patients use exfoliating cleansers, physical brushes, and then creams with light acids multiple times a day. It's way too much."

You should only exfoliate one to two times a week unless you have very oily skin and are advised to do more by a doctor. "I am more about barrier repair and providing calming ingredients rather than overdoing it on the other side of the spectrum," said Dr. Bhanusali.
