A product in your skincare routine may cause an allergic reaction, pimples, or other irritation. Think about the cosmetics, skin care products, and hair products you use. Cut back on all of them and slowly reintroduce them back into your routine one by one. This way, you can determine which might be causing your skin to break out.  If redness is associated with swelling of the face, especially lips or tongue, or trouble breathing, seek immediate medical attention. In the United States, call 911. Start with the products you have added most recently, since these are the most likely to have triggered a reaction. You can schedule an appointment with an allergist or dermatologist. Either can do a patch test, during which small amounts of chemicals will be applied to the skin and the treated skin will be monitored for a reaction. You may just have sensitive skin. If so, some brands have sensitive-skin product lines; classic examples include the Aveeno Ultra-Calming and Eucerin Redness Relief lines. After you figure out which chemical is at the root of your redness, cut out any product from your routine that contains that chemical as an active or inactive ingredient. Use warm water: both hot and cold water can cause your skin to dry out. If you wash it the wrong way, you can make your skin more irritated and redder. You should wash with a sensitive cleanser, one without fragrance, and avoid any that contain alcohol or other drying agents. Try products such as Cetaphil or Purpose.  Pat dry with a soft towel when done. Do not scrub your face, which can cause your skin to become more irritated.  Try cleansers with sulfates such as Rosanil. These ingredients will help with inflammation.  If your redness involves pimples and you do not have sensitive skin, try products that have benzoyl peroxide such as Clearasil. After washing your face, immediately apply a moisturizing facial cream (or lotion) over the skin to lock in moisture.  You can also store your lotion in the refrigerator and apply it to your face when cold....
