Q. If you have acne as a teenager, are you more likely to get rosacea as an adult?

Q. I have very large pores and am very oily in the "T" zone of my face. Is this common for rosacea sufferers?

A. There is no standard skin type for rosacea patients. Many sufferers experience dry, flaky skin, while others may have normal or oily skin. The key is to identify your skin type and use medication and skin-care products that are suitable for you.

Q. If I take long-term medication consistently, will it lose its effectiveness?

A. Topical therapy is commonly prescribed to control rosacea on a long-term basis, and no evidence has suggested that it loses effectiveness. A long-term controlled clinical study found that 77 percent of rosacea patients consistently using topical metronidazole remained in remission, while 42 percent of patients using no therapy had relapsed within six months.

Q. Sometimes my rosacea flare-ups look like mosquito bites and itch. Is this common?

A. A rosacea flare-up is characterized by a more intense outbreak of redness, bumps or pimples. For some sufferers, the bumps caused by rosacea may resemble mosquito bites. For others, these bumps are generally redder in appearance. It is not uncommon for rosacea patients to itch from dry skin, which can be helped by using a moisturizer.

Q. Can being anxious or nervous contribute to a rosacea flare-up? I do a lot of public speaking and find my face sometimes gets red and swollen before an engagement.

A. Since anxiety and nervousness are forms of emotional stress, it's quite likely that the anticipation of your speaking engagement could result in a rosacea flare-up. In a National Rosacea Society survey of 602 patients, 88 percent said their rosacea often or sometimes flares up when they are under emotional stress.
