Pathophysiology

Pathophysiology refers to how the nature of a disease (its pathology) manifests through changes in bodily functions (or physiology). Sometimes these changes express themselves as symptoms but often they appear symptomless to the patient and only manifest in blood test results and other diagnostic techniques. Skin conditions have a complex pathology and often affect physiology in unexpected ways. 

Homeostatic Dysregulation

The redness of the skin is due to an increase in blood supply to the capillaries. When a layer of skin is shed, the new skin surface sometimes looks almost like normal skin, but unfortunately will return to the previous shade of red within a few hours. However, the real problem is not the redness itself but that the skin is dry and has lost the ability to sweat properly; the result is a dysfunction of the body’s normal temperature control and of its natural electrolyte balance.
