It is National Acne Awareness, which follows the much more significant skin cancer awreness month. I say this since most people who have acne are all too aware that they have it, while, unfortunately, there are many people harboring skin cancers that do not realize it. Who thought of this month anyway? Was it to make sure that those with acne felt even more "picked" on?
There is not a single cause and this accounts for the various apperances acne may assume.
