Why does acne form?

Quizplus · Accepted Answer

The hair,sebum,and keratinocytes that fill the narrow follicle may produce a plug,which is an early sign of acne.The plug prevents sebum from reaching the surface of the skin through a pore.The mixture of oil and cells allows bacteria Propionibacterium acnes (P.acnes)that normally live on the skin to grow in the plugged follicles.These bacteria produce chemicals and enzymes and attract WBCs that cause inflammation.Inflammation is a characteristic reaction of tissues to disease or injury and is marked by four signs: (1)swelling,(2)redness,(3)heat,and (4)pain.When the wall of the plugged follicle breaks down,it spills sebum,shedding skin cells and bacteria into the nearby skin,leading to lesions or pimples.
