Allergic reactions that affect the face can lead to raised welts, swollen lips, and watering eyes. Beauty products or hay fever often cause these reactions.
A person can treat and prevent their allergies, once they know what is causing them, even though they are annoying when they happen.
Allergies may be especially common on the face because the skin is more sensitive than elsewhere, and because of various face creams and other products people use on their faces.
