Skin Allergy is the allergic condition that has prevailing symptoms on the skin and these are often triggered in a comparatively shorter period. Some of the common skin allergies such as allergic contact dermatitis, urticaria (hives) and photoallergy are usually experienced amongst patients. Clinical symptoms for allergic contact dermatitis often occur 1-2 days after exposure to an allergen. Photo allergy symptoms may occur somewhat earlier than allergic contact dermatitis. Urticaria has an extreme reaction and often occurs within minutes after exposure. Skin allergies are common and so are the allergens causing it. Causes of skin allergies are exposure to external allergens like metals and chemicals that can penetrate the skin but it gets triggered with internal allergens as well, like proteins and other food agents present in the diet. When in contact with external agents like cosmetics, body care products, hair dyes, detergents, textiles, jewelry, etc., the skin develops immediate reaction and shows the symptoms of allergy. The most common contact allergens are nickel, fragrances, and thimerosal (preservative). At least 15% of the population experience allergy when exposed to physical contact with allergens.At times, skin allergy comes as an occupational hazard as certain occupational groups are vulnerable to developing skin allergies. Professions involving frequent hand washing and working with irritant and sensitizing agents (e.g. rubber chemicals, fragrances, preservatives, dyes, metals) stimulate the reaction leading to an allergy.Atopic dermatitis, also called infantile eczema, is a chronic disease with an itchy rash that often appears in early childhood. More than 65% of children with atopic eczema grow out of it before adolescence. The trigger factors remain unidentified but children with allergic and asthmatic parents have an increased risk of developing atopic dermatitis. Hence, apart from environmental factors and food substances, poor genetics or hereditary have also been registered as the causes
