Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. Acne usually appears on your face, neck, chest, back and shoulders. Depending on its severity, Acne can cause emotional distress and scar the skin. The earlier you start treatment, the lower your risk of lasting physical and emotional damage.
Causes
Hair follicles are connected to oil glands. These glands secrete an oily substance (sebum) to lubricate your hair and skin. Sebum normally travels along the hair shafts and through the openings of the hair follicles onto the surface of your skin. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.
Sometimes bacteria that live on our skin, also get inside the clogged pore. Inside the pore, the bacteria have a perfect environment for multiplying very quickly. With loads of bacteria inside, the pore becomes inflamed (red and swollen). If the inflammation goes deep into the skin, an acne cyst or nodule appears.

Acne signs and symptoms vary depending on the severity of your condition:
- Whiteheads (closed plugged pores)
- Blackheads (open plugged pores — the oil turns brown when it is exposed to air)
- Small red, tender bumps (papules)
- Pimples (pustules), which are papules with pus at their tips
- Large, solid, painful lumps beneath the surface of the skin (nodules)
- Painful, pus-filled lumps beneath the surface of the skin (cystic lesions)
