Most common in people with light complexions, especially those of Northern and Eastern European heritage, rosacea is characterized by facial flushing or blushing, facial erythema, papules, pustules and telangiectasia. People with rosacea usually experience both periods of increasing severity in their condition and periods of improvement.

Because the early stages are often mistaken for sunburn, allergies or rash, many people with rosacea don’t realize they have a condition for which treatment is available. In its earliest stage, rosacea begins as a redness that looks like a blush or sunburn. The redness may last for hours or days, and some notice a burning or stinging sensation. Left untreated, rosacea worsens over time.

In its second stage, rosacea causes papules (small, red and solid pimples) and pustules (pus-filled pimples) to appear. You may also notice small, visible blood vessels on the surface of the skin. They look like thin red lines. About half of those with rosacea experience eye irritation. Your eyes may feel gritty and appear watery or bloodshot.

In its most severe stage, rosacea causes facial skin to swell and thicken. Facial pores become more noticeable, and the frequent papules and pustules may cause scarring similar to that caused by acne. The nose may swell, developing a bulbous enlargement. This condition is known as rhinophyma and is more common in men than women (think W.C. Fields).

Attempts to self-manage rosacea with over-the-counter remedies often leave people frustrated because the redness, papules, pustules and other symptoms persist. Often, the problem progresses and might even become irritated by over-the-counter products. Learn more about the lifestyle triggers that can exacerbate rosacea.
