Abstract

Objective: To determine the prevalence of Demodex infestation in acne patients and to compare clinical characteristics between Demodex dermatitis and Demodex presence. Methods: A cross-sectional study was conducted on 134 patients with acne vulgaris at Can Tho Dermatology Hospital from 2024 to 2025. Results: The prevalence of Demodex infestation was 47%. Females accounted for 72% of cases, with a mean age of 21.4 ± 6.2 years. High mite density was significantly associated with greater acne severity (p <0.001), more frequent subjective symptoms, particularly pruritus (p <0.001), and inflammatory lesions such as pustules, nodules, and cysts (p <0.05). Infestation was also more common in oily and dry skin types (p <0.01), while no association was observed with BMI (p = 0.47).
