May 24, 2005 - A recent study published in the Journal of Cosmetic Dermatology reports that mineral oil, a common ingredient in many skin care products, does not cause breakouts on the face as was previously thought.

Joseph DiNardo with Pharma Cosmetix Research, LLC, inRichmond VA points out in his study that while industrial grade mineral oil may be comedogenic, cosmetic grade mineral oil is not. Comedogenic is a term used to describe cosmetics that cause comedones, more commonly known as blackheads and whiteheads.

Based on this information, mineral oil should rightfully be taken off the list of comedogenic substances, which was developed many years ago yet remains frequently quoted in dermatologic literature.

Further, consumers searching for effective skin care products need not look for those that claim they are "mineral oil free" but rather those that state they are non-comedogenic.
