Rosacea (ro-zay-sha) is a common, acne-like benign inflammatory skin disease of adults, with a worldwide distribution. Rosacea affects an estimated 16 million people in the United States alone and approximately 45 million worldwide. Most people with rosacea are Caucasian and have fair skin. The main symptoms and signs of rosacea include red or pink facial skin, small dilated blood vessels, small red bumps sometimes containing pus, cysts, and pink or irritated eyes. Many people who have rosacea may just assume they have very sensitive skin that blushes or flushes easily.
2. You're OD'ing on spot treatments. Overusing topical salicylic acid, benzoyl peroxide, or sulphur over-the-counter treatments can dry out your skin, causing it to produce more oil and possibly blemishes. Those ingredients can actually make the appearance of your pimples look worse, since the active ingredients can slightly burn the top layer of your skin if used too often, making the pimple appear even redder and harder to conceal than if you had just left it alone.

Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
