The skin signs of rosacea vary by the particular type, according to the American Academy of Dermatology. Erythematotelangiectatic rosacea is characterized by the tendency to flush or blush more than other people and spider veins and blood vessels that can be seen under the skin.
In papulopustular rosacea, the skin is swollen, red and suffers break-outs that resemble acne, claims the American Academy of Dermatology. Phymatous rosacea causes the skin to thicken and have a bumpy feel to it. Some people have more than one type of rosacea at the same time. Others who have had rosacea for a while have a permanent red area in the middle of their face. Other symptoms include skin that is sensitive and feels like it's burning or stinging. The skin may also be rough, dry or scaly.
No one knows the cause of rosacea, but it is more prevalent among middle-aged, fair-skinned women, says Mayo Clinic. It can also be triggered by certain foods and stressors such as extreme heat and cold, emotional upsets, sunlight, too much exercise and corticosteroids. Drugs that cause the blood vessels to open up may also contribute to flare-ups of rosacea. Though rosacea can't be cured, the flare-ups can be controlled. Doctors prescribe antibiotics, which also reduce the condition's inflammation, and acne medications to ease rosacea symptoms.
