It’s important to opt for a good and healthy skin care regime from the very beginning. “It’s like getting your body into shape: Just because you haven’t exercised before doesn’t mean you can’t start now and see great results,” says Joshua Zeichner, MD and Director of Cosmetic and Clinical Research at New York City’s Mount Sinai Hospital.
