The facial skin of rosacea sufferers may be more susceptible to irritants due to impaired barrier function, a recent study found, resulting in the dryness experienced by many with the disorder.

While cold blustery weather and ever-advancing age can make dry skin a menace for rosacea patients, medical therapy and careful skin care can help manage and control this problem, according to Dr. Doris Day, clinical assistant professor of dermatology at New York University.

Q. Is oily skin usually a precursor to rosacea?

A. There is no evidence that oily skin leads to rosacea. Many rosacea patients experience dry skin, while others may have normal or oily skin, or both. The key is to use skin-care products and procedures that are suitable for your individual case.

Q. Has rosacea been linked to other diseases, particularly those relating to the immune system?

Q. My face is dry but I am concerned about using a moisturizer. Won't it block my pores and prevent my topical medication from being absorbed?

Q. Can indoor temperature affect my rosacea?

A. It is possible that indoor temperature could affect rosacea in certain cases, since anything that causes a sufferer to flush may have the potential to lead to a flare-up. Hot weather has been documented on surveys as a rosacea trigger for 53 percent of sufferers, and being "too warm" indoors can also induce flushing.

In addition to the visible symptoms of rosacea, many sufferers report yet another problem -- dry skin, which often results in itching, burning and stinging sensations.
