A skin allergy is a physiologic reaction caused when the immune system wrongly identifies a common non-harmful substance as harmful to the skin. Triggers may include: gardening, dyes or chemicals in fabric, chemicals in cosmetics, certain shampoos, conditioners, lotions, and moisturizers.
Usually, once the skin has been exposed to an allergic substance, a rash that can be red, itchy, rough, scaly, or blistering will appear, along with swelling of the skin and allergic conjunctivitis (red, itchy, watery eyes).
Some over the counter creams or ointments may make your skin worse. With the help of an experienced dermatologist, allergic reaction symptoms can clear up in a matter of a week.
