Rosacea (cont.)Is rosacea like acne?

Rosacea is basically different than acne, although the two can coexist. It is also sometimes called "adult acne." Unlike common acne, rosacea is not primarily a plague of teenagers but occurs most often in adults (ages 30-50), especially in those with fair skin. Different than acne, there are usually no blackheads or whiteheads in rosacea. Furthermore, most teens eventually outgrow acne whereas patients with rosacea don't generally outgrow it. Rosacea consists mostly of small red bumps that are not "squeezable" or extractable like blackheads. Squeezing a rosacea pimple usually causes a scant amount of clear liquid to expel. Unlike traditional acne where professional extractions can help remove whiteheads and blackheads, squeezing or extracting rosacea bumps does not help improve the rosacea. People with rosacea tend to have a rosy or pink color to their skin as opposed to acne patients whose skin is usually less red.


Rosacea strikes both sexes and potentially all ages. It tends to be more frequent in women but more severe in men. It is very uncommon in children, and it is very infrequently seen in darker skin tones or black skin.


What are the causes and risk factors of rosacea?


The exact cause of rosacea is still unknown and remains a mystery. The basic process seems to involve dilation of the small blood vessels of the face. Suspected causes of rosacea include but are not limited to genetic factors, genetics plus sun exposure, a mite sometimes found in hair follicles (Demodex folliculorum), the bacteria Helicobacter pylori (that is associated with stomach ulcers), gastrointestinal disease, and medications that cause blood vessels to widen. There seems to be a hereditary component to rosacea in a large number of people. Often people have close family members with rosacea.


Rosacea tends to affect the "blush" areas of the face and is more common in people who flush easily. Additionally, a variety of triggers are known to cause rosacea to flare. Emotional factors (stress, fear, anxiety, embarrassment, etc.) may trigger blushing and aggravate rosacea. A flare-up can be caused by changes in the weather like strong winds or a change in the humidity. Sun exposure and sun-damaged skin is generally associated with rosacea. Exercise, alcohol consumption, emotional upsets, and spicy food are other well-known triggers that may aggravate rosacea. Many patients may also notice flares around the holidays, particularly Christmas and New Year's holidays.


Rosacea risk factors include fair skin, English, Irish or Scottish heredity, easy blushing, and having other family members with rosacea (called "positive family history"). Additional risk factors include female gender, menopause, and being 30-50 years of age.
