Q. I have special sunscreen, topical medication and special makeup. In what order should these three things be applied to my face?

A. From both medical and cosmetic standpoints, it makes much more sense to apply your medication before applying your sunscreen and makeup.

In addition, you should be sure to wait a few minutes to give the topical therapy a chance to dry before adding the sunscreen. Begin by waiting 10 minutes in between each application, and slowly reduce the drying time until you find the least amount of time your skin needs to completely dry. Then wait another interval in the same manner before applying cosmetics. Also, always check with your doctor because medicines vary.

Q. My husband flushes noticeably after drinking alcohol. When most dramatic, the flush seems to extend down his neck and across his chest, upper back and upper arms. Is this extensive spread of flushing typical of rosacea?

A. While rosacea is generally considered a facial disorder, surveys have shown that one in five rosacea patients have signs and symptoms on other parts of the body. Areas close to the face, such as the scalp, ears and neck, are more common sites, but some patients reported symptoms on their chest, back, arms and even their legs.

If your husband has not yet done so, he should talk to his doctor about evaluating these symptoms. Appropriate treatment and care may help him to avoid such extensive flare-ups in the future.
