THE COMMON EXPLANATION:
Some people naturally redden with shyness, alcohol consumption, or stress. And, of course, flaming skin is also a result of unprotected sun exposure—which is a common problem for guys who earn their living outdoors.
THE BIGGER PROBLEM:
If the long term redness isn’t caused by one of the above—and it doesn’t go away—you may have rosacea, a chronic skin condition that happens when the blood vessels on the face dilate and increase blood flow near the surface of the skin, making it appear red and flushed, similar to when you’ve had a bit too much to drink. Rosacea is harmless—although it can make you feel self-conscious—and it’s not usually caused by an underlying medical condition. It’s typically treated with antibiotics, but there is no cure.
