Q. I suffer from bumps or pimples that aggravate my lips. Is this caused by my rosacea?

A. Rosacea usually affects the cheeks, nose, chin or forehead. Bumps or pimples around the mouth could be a sign of another skin condition such as perioral dermatitis. This disorder usually presents a red, slightly scaly rash around the mouth and is especially common in women and children. There may be clusters of small bumps around the mouth. Flushing, blushing or visible blood vessels are not usually associated with this condition; however, concurrent rosacea may also be present. You should see your dermatologist for an accurate diagnosis and appropriate therapy.
 

Q. Does topical medication get washed away when you perspire? My medication says to use it twice a day, but should I also reapply it after exercising?

A. Once topical medication is absorbed into the skin, the beneficial effects are not washed away when you perspire. Dermatologists recommend applying topical medication to clean, dry skin and waiting five to 10 minutes before applying other skin-care products.

It is important that you use your medication as prescribed. If it requires application twice a day, it can easily be used as part of your routine skin-care regimen in the morning before going out for the day and in the evening before bedtime.
