Abstract

Background: Hyperpigmentation disorders (HPDs) are prevalent pigmentary conditions primarily driven by increased melanin production, which can significantly impact patients' quality of life. Accurate diagnosis, severity assessment, and continuous monitoring are critical for effective treatment. However, there remains a need for non-invasive, reliable methods to evaluate HPD severity. Objective: This study aims to evaluate the efficacy of the VISIA skin analysis system in assessing facial. Methods: A cross-sectional descriptive study was conducted with 110 female patients, aged 18 years or older, presenting with facial hyperpigmentation at the Dermatology - Cosmetic Dermatology Department, University Medical Center, Ho Chi Minh City, between December 2023 and June 2024. Results: The mean age of onset for HPDs was 31 ± 10.4 years, with an average disease duration of 12.8 ± 9.6 years. The most commonly affected areas were the cheeks, chin, and nose. Melasma, particularly mixed-type, accounted for 80% of cases. Clinically, light brown lesions were predominant, indicating mild HPD severity. The average HASI score was 9.0 ± 6.1. Significant differences were observed in mean HASI values based on hyperpigmentation type, lesion type, and color. VISIA indices, including red area, surface spots, and UV spots, showed correlations with age and clinical severity. Significant associations were found between the HASI scores, clinical color assessments, and VISIA indices. Wood's lamp examination further highlighted variations in VISIA indices across different HPD subtypes. Conclusions: Melasma, especially mixed-type, is the most prevalent form of HPD. VISIA indices correlate strongly with both HASI scores and clinical severity assessments, validating the VISIA system as a reliable tool for evaluating and monitoring HPD progression. These findings support the intergration of VISIA into clinical practice to enhance HPD management.
