acne medication : Acne is an inflammatory affection of the sebaceous glands. Acne, in its mildest form of development, consists of a small papule; usually seated on the face, chest, or back. The papule is red, pointed, and may be slightly sore to the touch, presenting the usual features of a localized inflammation. The papules may vary in number from one or two to several hundred, scattered over the nose, cheeks, forehead, temples, chest, and back. The little pimple may, on pressure with the finger, present slight firmness, indicative of the inflammatory effusion.
