Contact allergy is a skin reaction to a substance it comes into contact with. In everyday life, it is often called simply \u00abskin allergy,\u00bb but more accurately, it is allergic contact dermatitis. This rash is not contagious, but it can be very unpleasant: the skin itches, turns red, dries, or even becomes covered with blisters. Most often, the reaction does not appear all over the body, but specifically where there was contact with metal, cosmetics, paint, rubber, glue, plants, or other substances. If the cause is removed, the rash often disappears within 2\u20134 weeks.<\/p>\n

It is important not to confuse contact allergy with ordinary skin irritation. There are two main types of contact dermatitis: irritant and allergic. Irritant occurs when the skin is damaged by soap, detergents, solvents, disinfectants, water or other aggressive factors. Allergic is an immune reaction that usually does not appear upon first contact, but after the body has already "met" the allergen and become sensitive to it.<\/p>\n

Most often, suspicion arises when the rash is clearly associated with a specific thing or situation. For example, the skin itches under earrings, under a watch strap, after a new cream, hair dye, gloves, a patch or household chemicals.
