By some recent estimates Rosacea afflicts 13 million Americans. Rosacea is a chronic disease which usually first appears as subtle reddening on the face. Over time this may develop into some inflammation and may be accompanied by skin eruptions. About half of Rosacea suffers also have some sort of symptoms with their eyes (known as Ocular Rosacea). If left untreated, over time Rosacea can result in the appearance of red lines which result from swollen or damaged veins.
Rosacea most commonly afflicts adults between the ages of 30 and 60 though it has been know to afflict children. Symptoms usually start to appear to people in their 30s or 40s. Men and women are equally likely to to be affected and there seems to be a genetic aspect to the disease.
Symptoms include:
Flushing or blushing that occurs easily and often and lasts longer than normal.
Rashes and redness on part or all of the face. (Known as erythema). Often has the appearance of sunburn and may become worse over time
Burning or stinging sensations
Skin pimple-like eruptions which may be solid (called papules or nodules) or puss filled (known as pustules). This may look a lot like acne but whiteheads or blackheads (common symptoms of acne) and not normally present. This skin condition may result in dry skin.
Visible red lines on the face called telangiectasis. These lines are caused by enlarged or damaged blood vessels.
Red, sore or gritty eyes or eyelids. Eye symptoms are know by the term Ocular Rosacea
The exact cause of Rosacea is still largely unknown, however the symptoms are reasonably well understood as are a variety of lifestyle factors (such as particular foods and activities) that are known to trigger outbreaks in people that have the disease.
