what causes the skin to look blotchy
Body Heat. The most likely cause of red blotchy skin is an increase in body heat. During times of intense stress and anxiety, your body heat rises, and this releases a chemical inside of your body known as histamine-the same immune system chemical that is released during an allergic reaction.
Quick and Long-Term Fixes for Blotchy Skin. While blotchy skin can be caused by a number of factors you cannot control, including heredity, there are also factors that you can manage, such as sun damage. Your skin speeds up the production of skin cells called melanocytes to protect against sunlight.
