Don't: Over-Exfoliate, Over-Cleanse, Over-Apply

Why it's really that bad: Both dermatologists we spoke to have seen patient after patient who assumes that if a little is good, more is undoubtedly better: Women who wash their face 4 times a day, exfoliate in the morning and at night, pile on 4 wrinkle fighters or blow right by the "apply a thin layer" direction on acne spot treatments and lay them on thick. "The only thing you're going to accomplish is drying out and irritating the skin and making whatever problem you were trying to solve worse," Day says.
The fix: Best results come from following the directions on the product. If you're doing that but still not getting what you want from your current regimen, ask your dermatologist how you can safely improve it.
