Acne is a condition which develops in and around the hair follicles and their oil producing glands called the sebaceous glands. Although we have these glands all over the surface of our body, acne only develops on the face, chest, and back.
The oil produced by sebaceous glands is called sebum , which begins to appear soon after puberty. When the oil glands become blocked, comedones – or blackheads and whiteheads – are formed, bacteria in the deeper part of the hair follicle and beneath the sebum blockage release chemicals which act upon the sebum and break it down to release other chemicals. These chemicals make the skin around the hair follicle red and inflamed, resulting in a pimple. In bad cases, pus may develop within the pimple. Large, painful swellings called nodules and cysts may develop and result in scarring after the condition has eventually settled. These scars can either be depressed and sunken, or bulging and hard.
