Abstract

Objective: To assess the self-reported prevalence of Sensitive Skin Syndrome (SSS) and identify its associated factors. Materials and Methods: A total of 198 participants who presented to the National Hospital of Dermatology and Venereology were enrolled. After being provided with a formal definition of SSS, participants self-assessed their condition and answered questions about potential related factors. Results: Among the 198 participants, who exhibited a female-to-male ratio of 1.82:1, the self-reported prevalence of SSS was 60.6%. The SSS prevalence showed no statistically significant association with age or gender (p>0.05). Individuals with SSS were significantly more likely to react to various triggers (p≤0.001). The factors most strongly associated with SSS were exposure to wind (OR=8.531), physical exercise (OR=8.333), psychological stress (OR=7.967), and soaps/ detergents (OR=7.618). Other common triggers included hot/dry air, sun exposure, cold/humid air, use of hygiene soaps/cleansers, use of cosmetics, exposure to smog/pollutants. The median self-perceived sensitivity score (VAS) was 5 (interquartile range: 3–6). The primary sensory symptoms were itching (70.0%) and stinging (33.3%), erythema was also a common physical sign (54.2%). Symptoms were most frequently exacerbated during winter (38.3%) and summer (37.5%). Conclusion: Sensitive skin syndrome is a common condition, affecting individuals regardless of age or gender. It is characterized by subjective sensory symptoms and objective erythema, significantly triggered by a wide range of environmental, chemical, and endogenous factors. Notably, symptoms tend to worsen during winter and summer.
