No-one part of your body acts independently with an additional. That is why a number of systemic diseases have linked skin abnormalities. The reason this concept is important is it to be not a generally well-accepted view from our medical community and then the approach to skin problems is flawed. Rather than addressing the cause of these problems, we are almost always addressing symptoms like inflammation, flaking or swelling. This specific philosophy has permeated our own society; acne... take antibiotics, redness... here is another steroid... or maybe a good laser treatment. The assumption is the skin is acting unmanageable, that it has disassociated itself from other body and only we have learned to control it. WRONG! Most skin conditions are unintended side effects of a bigger problem elsewhere by the body processes.
