Dermatologist Discusses Four Types Of Rosacea.

In the "Skin Deep" column in the Miami Herald (2/15), dermatologist Leslie Baumann, MD, writes, "According to the National Rosacea Society, this common yet poorly understood skin condition affects more than 16 million Americans." According to researchers, "there seem to be four distinct types of rosacea." For rosacea precipitated by the dilation of blood vessels, "new drugs are being researched to prevent the dilation." The bumps of acne-like rosacea "may be caused by organisms on the skin such as demodex (a particular type of mite) or by organisms that have not yet been identified." Laser treatments are effective for treating "visible broken blood vessels," which "are likely caused by years of dilating and constricting." Laser surgery can also treat rosacea-related "growth on the nose known as rhynophyma."
