Introduction:
Vitiligo is an incurable, slowly progressive skin condition, the prevalence of which ranges from 0.4 to 2.0%. Health-related quality of life (HRQoL) refers to self-perceived well-being associated with the presence of a disease and its treatment.
Methods:
Cross-sectional study at a dermatological center. Adults with non-segmental vitiligo (NSV) were included, while patients with other pigmentary disorders and other types of vitiligo were excluded. The VitiQoL questionnaire (0 = no skin involvement, 90 = maximum skin involvement), the Vitiligo Extent Score (VES) and the Vitiligo Area Scoring Index (VASI) were applied.
Results:
492 patients did participate; 63% were women. An average score of 32.6 was obtained on VitiQoL (95% CI = 30.6-34.5). Self-perception of severity and HRQoL were correlated (r = 0.568, p < 0.001). Age, the female gender, lower education and higher self-perceived severity were associated with poorer HRQoL. The proportion of subjects who reported an addiction was similar in the worst and best HRQoL groups (28% vs. 32%, p = 0.23).
Conclusion:
Poorer HRQoL is explained by severity self-perception, concern about disease progression, appearance of the skin and necessary actions to avoid sun exposure during recreation.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
