Acne mechanicaWhen you have acne, it’s tempting to try to scrub it away. But decades of acne research shows us that physical irritation will actually cause acne. This is such a generally accepted condition amongst dermatologists and medical researchers that it has its own name: acne mechanica.

A recent article in the journal Dermatology once again reports on this problem. Three female patients presented with what can only be described as horrible acne. It came on fast and was in the area where they were scrubbing their face with various skin care products. The authors of the article considered the products to be non-comedogenic and ruled out the products themselves as the cause of the acne. In fact, in a nod to cosmetic companies, the authors state, “…nowadays, cosmetic companies are carefully testing their compounds for comedogenicity before marketing, and cosmetics are an infrequent cause of acne.” They go on to conclude, “…repetitive physical trauma could act as a trigger for severe inflammatory acne.”

The cases in this article are severe, but millions of people suffer with acne caused by everyday physical irritation. You can’t eliminate physical irritation altogether, and you shouldn’t aim to do this since it will likely drive you pretty crazy. Instead, take a few minutes to become aware of sources of physical irritation and try to reduce or eliminate them when you can. Then get on The Regimen and add in some glycolic acid when needed and you will be nice and clear.
