Q. I am using a topical antibiotic to control my rosacea with great success. Should I suspend treatment for a couple of weeks to prevent developing a resistance to the medication?

Although rosacea flare-ups are a common aspect of rosacea, patients are able to successfully control them with medication and by avoiding factors that aggravate their condition, according to a recent survey by the National Rosacea Society.

In the survey of 2,083 rosacea patients on the nature of flare-ups -- the reappearance or increased intensity of symptoms -- 32 percent said they experienced flare-ups frequently, while 55 percent said they experienced them occasionally and 12 percent reported they rarely or never experience this problem.

Many physicians report that spring is "rosacea season," since the changing weather can bring so many rosacea tripwires to the forefront. Here are tips for minimizing the impact of the changing seasons on your condition.

Which came first, the chicken or the egg?

In rosacea, are visible dilated blood vessels -- called telangiectasia -- the result of damaged connective tissue, or is it the damaged blood vessels themselves that have a degrading effect on the connective tissue? Experts have discussed both possibilities.

Rosacea's symptoms have been described in literature and depicted in art for more than 700 years, yet this common but little-known condition remains a mystery to most Americans. April was designated Rosacea Awareness Month by the National Rosacea Society to increase public understanding of rosacea and encourage people who may suffer from the disorder to seek professional diagnosis and appropriate therapy.

The National Rosacea Society has received wide support from rosacea sufferers for its newly established research grants program. Individual donations totaling more than $250,000 have been received to date, and are now earmarked for funding important scientific research into the potential causes and other key aspects of this poorly understood disorder.
