The terms non-comedogenic and non-acnegenic mean pretty much the same thing: These products won't cause blackheads, whiteheads or acne. These moisturizers will almost always be oil-free, and they can be found easily and inexpensively. Even drug store brand-moisturizers have been scientifically proven to benefit inflamed skin. Neutrogena, for one, does a lot of testing on its products, says Dr. Susan Goodlerner, Clinical Associate Professor of Dermatology at Harbor-UCLA Medical Center in Torrance, Calif.
She also points out that these terms, while helpful when looking at labels and selecting a moisturizer, aren't actually regulated by the Food and Drug Administration (FDA). So, be careful at the drug store: There may be some trial and error involved in finding the moisturizer that works with your skin type, but it doesn't have to be expensive. Once you've found the moisturizer that keeps your acne in check, stick with it.
