The skin is an extremely complex and constantly remodeling organ that is not only a physical protective barrier but also an integration of the nervous system, vascular system, immune system and endocrine system.
Given its complexity, over 150 diseases have been identified that affect the skin, its innervation and blood supply. Many of these afflictions manifest with severe intractable numbness, chronic pain and/or itch, which respond poorly to existing therapeutics.

Existing research, much of it conducted by the co-founders of Intidyn, have shown that microscopic immunochemical assessments of skin sections cut from 3mm punch biopsies are an invaluable means:
- For elucidating the nature and potential basis of skin and nerve pathologies.
- For assessing the efficacy of therapeutics and providing insights for potential future therapeutic strategies.
- Diagnosing existing and impending disease - such as diabetes - before the overt manifestation of the disease, thereby providing the potential for appropriate intervention before a more intractable problem occurs.
- Detecting potential detrimental side effects associated with drug development for other diseases such as arthritis and hypertension. This is due to the fact that the skin is a constantly remodeling structure that integrates multiple systems.
- Evaluating the specificity of novel reagents, such as antibodies, that are designed to detect the location of specific functional molecules.
Thus, skin biopsies provide an important diagnostic tool for impending or existing disease, and for developing therapeutics.
