I can't get rid of dry skin from an allergic reaction? Tips/suggestions?

Moisturizer and time. After an allergic reaction that affects the skin, it can take time for the skin to heal. There are many different types of skin reactions including blisters, hives, sandpaper-like, oozing, sunburn type, etc. As long as the trigger of the skin reaction has been removed, antihistamines may help with itching, but moisturizers especially ointments applied within 3 minutes of a bath can help dry skin.
