Acne (Acne Vulgaris)

Overview:

Acne, or acne vulgaris, an inflammatory disorder of hair follicles, is present, to some degree, in more than 90% of humans at some point in their lives. Only 3% of men will have acne into their 40s, but 12% of females will. Females who have never experienced acne in their teens can get breakouts in their twenties. Skin oil called sebum is overproduced under the influence of hormones. This can plug hair follicles leading to overgrowth of normal skin bacteria that is trapped in the plugged follicle. Certain medications such as lithium, cortisone, hormones, iodides, some seizure medications, or isoniazid can also cause or worsen acne lesions.
