From a sunburn to an allergic reaction, there are many situations in which your skin can become red or irritated. It may be because extra blood rushes to the skin’s surface to fight off irritants and encourage healing. Skin redness can also come from exertion, such as after a heart-pounding exercise session.
It’s not always cause for concern, but skin redness can be irritating and uncomfortable. Figuring out its underlying cause can help you treat your skin and keep it from happening again.
