Causes Of Acne

Three factors contribute to the formation of acne:

Overproduction of oil (sebum)

Irregular shedding of dead skin cells resulting in irritation of the skin follicles

The accumulation of bacteria

Acne occurs when hair follicles are placed in oil and dead skin cells. Each follicle is connected to sebaceous glands. These glands secrete an oily substance called sebum to lubricate hair and skin. Sebum normally travels along the hair shaft and then through the opening of the follicle on the surface of your skin. When your body produces excess sebum and dead cells that can both build the hair follicle and form together as a soft plug.

This connector can cause the follicle wall to swell and produce a whitehead. Alternatively, the connector will be open to the surface and darken, causing a blackhead. The buttons are raised red spots with white centers that develop when blocked hair follicles become inflamed or infected. Blockages and inflammation that develop deep inside the hair follicles produce lumps beneath the surface of the skin called cysts. Other pores, which are the openings of the sweat glands in your skin that are not generally treat acne.

It is not known what causes increased production of sebum that leads to acne. But many factors - such as hormones, bacteria, certain medications and heredity - play a role.

Contrary to what some believe, fatty foods and chocolate have little effect on acne. Studies are underway to determine if other dietary factors - including starchy foods like bread, bagels and chips, which increases blood sugar - may play a role in acne.

Acne is not caused by dirt. In fact, washing irritates the skin too hard or cleansing with harsh soaps or chemicals on your skin and make acne worse. A simple skin cleansing to remove excess oil and dead skin is all that is needed.
