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.

For instance, topical treatments come in different formulations. Gel formulations are suitable for patients with normal to oily skin. Lotion formulations are a good choice for patients with normal to dry skin. Cream formulations may be especially suited for dry skin.

In addition to selecting the right topical formulation, rosacea patients should opt for skin-care products that work well with their skin types.

Q. Is there any kind of test that will tell you that you definitely have rosacea?

A. There are no histological, serological or other diagnostic tests for rosacea. A diagnosis of rosacea must come from your physician after a thorough examination of your signs and symptoms and a medical history. During your exam you should explain any problems you are having with your face, such as redness; the appearance of bumps or pimples; swelling; burning, itching or stinging; and other information.
