Acne is a skin condition which occurs when your hair follicles become plugged with oil & dead skin cells.This condition causes problems like whiteheads, blackheads or pimples, and usually appears on the face, forehead, chest, upper back and shoulders. Acne is most common among teenagers, though it affects people of all ages.
Effective treatments are available, but acne can be persistent. The pimples and bumps heal slowly, and when one begins to go away, others seem to crop up.
There are many stages of acnes such as mild (few, occasional pimples), moderate (inflammatory papules), or severe (nodules and cysts).
Whiteheads (closed plugged pores)
Blackheads (open plugged pores)
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)
