Sunburns, genes play role in rosacea

March 10, 2009 That's the finding of new research released by the American Academy of Dermatology.

In the study 34 percent of those with the disease reported having a relative who also had the skin disorder, and 44 percent of people with rosacea reported having had blistering sunburns at some time, compared with just more than 5 percent of the others.

Authors advise people with a family history to regularly use broad spectrum sunscreen and other protective measures.
