Understanding the Sensitive Skin Subject to Achieve a More Holistic Diagnosis

Abstract

Sensitive skin Syndrome (SSS) is a complex global clinical phenomenon that is defined by the self-reported presence of different sensory perceptions, including tightness, stinging, burning, tingling, pain and pruritus and often without objective signs. Due to the subjective nature of this clinical condition, the diagnosis is complex and there is often a disconnect between what subjects feel and what medical professionals can observe. This chapter reviews the known underlying physiology, some of the triggering factors associated with SSS, co-morbidities as well as the psychological impact on individuals suffering from this condition. The goal is to bridge the gap between the physicians’ understanding and the subjects’ perceptions of this real-life condition that affects so many.

“…The HET‐CAM test was carried out in order to evaluate the level of ocular irritation of GE dyeing, provided that sensitive eyes are a major concern when developing haircare products [42] . As it can be seen in Figure 7, GE at concentrations 10 and 25 % did not cause any irritative damage to CAM at the end of the study (5 min of contact) At these concentrations, there was no hyperemia, hemorrhage and coagulation, which makes it compatible with the saline solution used as a negative control.…”
