Alternate Names : Acne Vulgaris, Pimples
What are the signs and symptoms of the condition?
Acne may occur on a person's face, neck, chest, back, shoulders,
scalp, and upper arms and legs. Comedones, or clogged pores, are the first
signs of acne. There are 2 types of comedones:
blackheads, which are incompletely clogged pores capped with blackened dust
whiteheads, which are completely clogged pores
A comedone may also break through the pore wall underneath the skin and release
its contents. This causes a pimple or pustule. If this substance is released
deep into the skin it will cause a cyst, which is a small, pus-filled bump
beneath the skin.
