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.
