Causes of Acne



Three factors contribute to the formation of acne:
  • Overproduction of oil (sebum)
  • Irregular shedding of dead skin cells leading to irritation of the hair follicles of your skin
  • Buildup of bacteria

Acne happens when the hair follicles become plugged with oil and dead skin cells. Hair follicles are connected to sebaceous glands. These glands secrete an oily substance referred to as sebum to lubricate your hair and skin. Sebum normally travels up along the hair shafts and then out through the openings of the hair follicles onto the surface of your skin. When your body produces an excess quantity of sebum and dead skin cells, the 2 will build up within the hair follicles and type along as a soft plug, making an atmosphere where bacteria will thrive.

This plug might cause the follicle wall to bulge and turn out a whitehead. Or, the plug is also open to the surface and will darken, inflicting a blackhead. Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected. Blockages and inflammation that develop deep within hair follicles turn out lumps beneath the surface of your skin known as cysts. alternative pores in your skin, that are the openings of the sweat glands onto your skin, are not normally concerned in acne.

Factors which will worsen acne
These factors will trigger or irritate an existing case of acne:
  • Hormones. Androgens are hormones that increase in boys and ladies throughout puberty and cause the sebaceous glands to enlarge and build additional sebum. Hormonal changes associated with pregnancy and also the use of oral contraceptives may also have an effect on sebum production.
  •  Sure medications. medicine containing corticosteroids, androgens or lithium are known to cause acne.
  • Diet. Studies indicate that sure dietary factors, together with dairy merchandise and carbohydrate-rich foods — like bread, bagels and chips, that increase blood sugar — might trigger acne.

Acne myths
Contrary to what some folks assume, these factors have very little impact on acne:
  • Greasy foods and chocolate have proved to possess very little to no impact on the event or course of acne.
  • Dirty skin. Acne is not caused by dirt. In fact, scrubbing the skin too onerous or cleansing with harsh soaps or chemicals irritates the skin and may build acne worse. straightforward cleansing of the skin to get rid of excess oil and dead skin cells is all that is needed.
