THE LATEST ADVANCES IN PREVENTION AND TREATMENT SPECIAL REPORT Rosacea
Sun exposure has always ranked as a major culprit in rosacea flare-ups. Now, scientists know why.

Boston University researchers have found that ultraviolet rays activate the body's production of vascular endothelial growth factor (VEGF), which is linked to the development of visible blood vessels, or telangiectasia.

Researchers hope the new discovery will lead to better treatment and prevention methods. In the meantime, if you have rosacea, wear sunblock with an SPF of at least 30 and a brimmed hat, and try to avoid the strongest sunlight (roughly between 10 AM and 2 PM).
