Acne -- in its most common form -- is a skin condition that causes outbreaks of whiteheads, blackheads, or pimples. It occurs when pores get clogged up by sebum, an oily substance made by glands inside the pore of every hair shaft. Sebum's main job is to lubricate and protect the skin and hair, but too much of it can lead to skin eruptions. Pimples are clogged pores that have been infected with bacteria and may redden, swell and fill with pus as the immune system fights back.

- What is the definition of acne?
Are acne and rosacea the same skin condition?
Rosacea and regular acne are not the same condition. Acne vulgaris, the type that is common among teenagers, causes whiteheads, blackheads, or pimples. Rosacea, on the other hand, is an inflammatory skin condition marked by a disorder of the facial blood vessels. In rosacea, these vessels are hypersensitive to stimuli such as sun, wind, skin irritants, and other triggers.
Rosacea can cause flushing, tiny broken facial blood vessels, eye irritation, an acne-like rash, and facial redness, burning, and swelling. Rather than clogged pores, rosacea acne consists of red bumps (papules) filled with clear fluid. People with rosacea often have red blotches on their nose, cheeks, chin, or forehead. Left untreated for years, the condition can sometimes cause a red bulbous nose (rhinophyma), which is more likely to occur in men. Unlike acne, rosacea is more common in people over 30.
What is plaque psoriasis?
Michael Roizen, MD, Internal Medicine, answeredPlaque psoriasis is the most common type of psoriasis. About 80% of people with psoriasis have it. This type of psoriasis usually occurs on the places you hear old relatives complain about the most: knees, elbows, lower back, and head (scalp). You can identify it by the characteristic raised, red patches of skin with white or silver patches of dead skin on top that flake off. It may feel as itchy as the old, wool costume you had to wear for your school play.
