Spicy foods, alcohol and exercise can all cause a blood rush to the skin. But flushing can also be a sign of rosacea, redness of the skin that usually affects those with fair, sun-damaged skin. According to experts, sun damage weakens the collagen around blood vessels, so they lose their ability to constrict and instead stay dilated, which causes the face to become red.
The best way to avoid that trigger flushing, it’s always best to use sun protection. Your doc may recommend rosacea treatment if sun protection doesn’t work. He may prescribe topical creams to diminish skin troubles like rosacea.
