Benzoyl Peroxide vs. Salicylic Acid: Which One Do You Need, and When

Audrey Noble

For those like me who have had acne since the moment they hit puberty, two ingredients have become mainstays in our day to day skincare routines: benzoyl peroxide and salicylic acid. We've been told these acne-fighting ingredients are the key to treating unwanted blemishes, and as a result, we sometimes use them like they're interchangeable. But they are in fact two very different ingredients that do very different things when it comes to acne.

We asked dermatologists Arielle N.B. Kauvar, MD, of New York Laser Skin Care and Arielle Nagler, MD, of the Ronald O. Perelman Department of Dermatology at New York University Langone Medical Center to break down for us these two powerhouse ingredients and how we are supposed to correctly use them. Scroll down to see what they had to say.
