Q. Is there any evidence that certain vitamins help control rosacea?
A. Studies have not been conducted to determine whether any vitamin may help control the signs and symptoms of rosacea. However, niacin, one of the B complex vitamins found in certain foods as well as supplements, may act as a vasodilator and consequently induce or intensify flushing. Rosacea sufferers affected by niacin therefore may wish to avoid foods or supplements containing this substance. As a preventive measure, aspirin taken one to two hours before ingesting foods or supplements with niacin may reduce the intensity of the flush.1
Q. What is the difference between rosacea and adult acne?
A. Although rosacea has sometimes been referred to as "adult acne," it is a distinctly different disease than acne. The bumps and pimples of adult acne resemble the papules and pustules of subtype 2 rosacea, but there are a number of important differences between the two disorders.
Unlike rosacea, which typically appears in the central facial area, acne often appears on the lateral as well as the central face, especially in older teens. Also, unlike acne, rosacea does not include comedones, commonly known as blackheads. In further contrast to acne, rosacea is usually associated with flushing, and ocular signs and symptoms are frequently present.
