Acne cosmetica is a term referring to acne caused by or made worse by cosmetics.[1]:240 The mechanism was presumably a chemically induced plugging of the pilosebaceous orifice. This was a significant problem for dermatologists in the 1970s and 1980s, but with the improved formulations produced by cosmetic chemists over the past thirty years, this is now a relatively rare diagnosis in daily practice.

The terms "non-comedogenic" and "non-acne(i)genic" appeared on moisturizers and other cosmetic compounds as re-formulations were introduced, sometimes associated with claims that the products were oil-free or water-based. Although early work produced lists of comedogenic chemicals in various strengths and vehicles, it became apparent that the actual comedogenicity of a product could not be predicted from its contents; rather the finished product itself needed to be use-tested.

The production of a low-grade folliculitis by some components of cosmetic products has led to misdiagnosis on occasion.

People may not attribute their reactions to their cosmetics at first, but may notice worsening symptoms after using certain face makeup, sunblock or lip products.

Reactions are more likely to occur if applied cosmetics are let to sit and are not stripped after use. [2]
