Itching, redness, and bumps on the skin surface are quite common and they may occur to almost anyone and may not be easily identified. Skin allergy can be caused due to a variety of reasons such as allergic reaction to some medicine, foods, and illness among others. Hives and eczema are regarded as the two most common allergic reaction rash. Atopic dermatitis is the most common allergy skin rash that is known to affect more than 20 percent of kids and about 3 percent adults. People affected with atopic dermatitis normally have a medical history of allergy itchy skin running through the family and though it can't be cured absolutely, the chronic skin allergy treatment by an experienced dermatologist can help in controlling the symptoms. Hives or urticaria is yet another common skin allergy that leads to warts or red bumps appearing on the skin surface. While hives can be cured with skin allergy medicine, if it persists for over 6 weeks, it is called chronic urticaria. Acute urticaria is the normally caused due to an exposure to any infection or allergen though the cause of chronic urticaria is largely unknown. Contact dermatitis is another reaction to allergens which leads to symptoms like blisters, rash, burning and itching which can be caused due to contact with some soaps, cleansers, shampoo, fabric conditioners, creams, lotions and even water. It can be reversed by skin allergy medicine and chronic skin allergy treatment.
