Rosacea is a condition most often seen in fair-skinned individuals. It is characterized by persistent redness and broken blood vessels on the face, most often caused by frequent flushing. These individuals might have a hypersensitivity to spicy food, hot food, alcohol, and the sun. Exposure to these triggers causes blood to rush to the face, causing it to redden. The condition can occur in darker-skinned people, too, but it likely to be less noticeable.

Rosacea has four phases, though it does not always progress through all four in every person. It starts with a tendency to flush frequently. Next, the condition may progress to the vascular level. The blood vessels swell and leak at a faster rate than normal, causing the skin to look puffy and feel warm. Dilated blood vessels are easier to see. They are commonly called spider veins. The skin can also become more sensitive to cosmetics or sunscreens, resulting in a slight burning or tingling sensation.

The inflammatory phase is characterized by small red bumps and pustules. It looks similar to acne, but is treated differently. A dermatologist can identify the underlying cause of the bumps.

In its final and most severe phase, late rosacea includes all the symptoms of the previous stages but they are more severe. More spider veins can develop and appear more noticeable. At its worst, the skin can thicken and cause the nose to become bulbous.

This condition is treatable. People with fair skin or frequent flushing should use a sunscreen with a minimum 30 SPF every day. Topical cleansers containing sulfur or sodium sulfacetamide can be used to gently clean the skin. Topical medications and creams may be prescribed to control the redness and inflammation. Broken blood vessels can be treated with lasers.

Because the condition progresses, it is important to see a dermatologist for an accurate diagnosis. A doctor can offer preventative measures to keep rosacea from worsening.
