1. These listings are only examples of common skin disorders that we consider severe
            enough to result in marked and severe functional limitations. For most of these listings,
            if you do not have continuing treatment as prescribed, if your treatment has not lasted
            for at least 3 months, or if you do not have extensive skin lesions that have persisted
            for at least 3 months, your impairment cannot meet the requirements of these skin
            disorder listings. (This provision does not apply to 108.07 and 108.08.) However,
            we may still find that you are disabled because your impairment(s) meets the requirements
            of a listing in another body system, medically equals (see §§ 404.1526 and 416.926
            of this chapter) the severity of a listing, or functionally equals the severity of
            the listings.
         
         2. If you have not received ongoing treatment or do not have an ongoing relationship
            with the medical community despite the existence of a severe impairment(s), or if
            your skin lesions have not persisted for at least 3 months but you are undergoing
            continuing treatment as prescribed, you may still have an impairment(s) that meets
            a listing in another body system or that medically equals a listing. If you do not
            have an impairment(s) that meets or medically equals a listing, we will consider whether
            your impairment(s) functionally equals the listings. (See § 416.924 of this chapter.)
            When we decide whether you continue to be disabled, we use the rules in § 416.994a
            of this chapter.
