What causes a rash to appear on your lips and around your mouth?
Actually, I did switch to a new brand of lip balm recently. Could that be the cause?
Definitely. Some people may be allergic to certain ingredients in lip balms or other facial products, leading to the appearance of a rash or irritation. I would recommend discontinuing the use of the new lip balm and seeing if the rash improves.
