What is rosacea?

Rosacea is a common vascular condition that is believed to be caused by inflammation. According to the National Rosacea Society, rosacea affects 16 million Americans. It’s often characterized by chronic and recurring heavy flushing, bumps, and blemishes, although there are other symptoms you could experience. Continue reading below to get basic information on rosacea causes, symptoms, triggers, and treatment.


Some researchers have linked rosacea to environmental and hereditary factors, while
others have suggested that rosacea stems from certain molecules in the skin. However,
the exact root cause remains unknown. The one constant most dermatologists agree
upon is that rosacea is a vascular, inflammatory condition.


Rosacea symptoms vary from person to person, and can often be mistaken for acne, eczema, or an allergy. Some common symptoms are:

Facial redness/flushing easily Bumps or blemishes (papules or pustules)
Burning or stinging (sensitive skin) Dry, tight, or itchy facial skin that may swell or thicken
Visible red veins (broken blood vessels) Burning, itching, watery eyes or swollen eyelids

While these symptoms aren’t dangerous to your overall health, they may worsen if left untreated. For some people, symptoms also take an emotional toll: one survey conducted by the National Rosacea Society found that rosacea sufferers had lowered self-confidence and that symptoms negatively affected professional interactions and social engagements.
