If you are allergic to certain sunscreen products -- more likely their ingredients -- you may consider trying out a new sunscreen you have not used before. To avoid an uncomfortable allergic reaction, test the product first to make sure it does not irritate your skin. Apply a small amount of sunscreen to the inside of your forearm for a few days. If your skin becomes red, itchy or irritated, you may be allergic to that product. The good news is that sunscreens come in many varieties, including gels, lotions, creams, wipes and powders, all with a variety of sun-protective ingredients. There's something out there for everyone, no matter your skin type or sensitivity. Most of the time, allergic reactions are due to fragrances or preservatives rather than the actual sunscreen.
