Questions and Answers About Acne: NIAMS (Excerpt)

The basic acne lesion, called the comedo (KOM-e-do), is simply an enlarged and plugged hair follicle. If the plugged follicle, or comedo, stays beneath the skin, it is called a closed comedo and produces a white bump called a whitehead. A comedo that reaches the surface of the skin and opens up is called a blackhead because it looks black on the skin's surface. This black discoloration is not due to dirt. Both whiteheads and blackheads may stay in the skin for a long time.

Other troublesome acne lesions can develop, including the following:

• Papules--inflamed lesions that usually appear as small, pink bumps on the skin and can be tender to the touch
• Pustules (pimples)--papules topped by pus-filled lesions that may be red at the base
• Nodules--large, painful, solid lesions that are lodged deep within the skin
• Cysts--deep, painful, pus-filled lesions that can cause scarring.

Acne: NWHIC (Excerpt)

Many women are very upset when they first get acne pimples at age 30 or 40. Most adults who develop acne at an older age, rather than just continue to have the acne that they first experienced as teenagers, have a type of acne called acne rosacea, or "rosacea", as it is commonly known.
