Contact Dermatitis
What can I expect from treatment?
If the cause of your rash is identified, and you avoid further contact with it, appropriate treatment will stop the itching and eventually cause the rash to disappear. In the case of "one time" exposure to strong irritants or sensitizers (like poison ivy), the skin rash will probably persist for about a week and then gradually subside. It will heal with peeling, and is not likely to leave any sort of scar.
Those rashes resulting from repeated contact — usually of a dry, thickened appearance — tend to be more persistent. The rash heals more slowly, often leaving a patch of darker skin. This, however, will eventually fade.
