Truncal acne: Bridging research gaps and enhancing clinical understanding

Acne affects individuals across all ages and ethnic groups. Truncal acne has received limited attention, and its mechanisms and characteristics remain poorly understood This article aims to provide a comprehensive analysis of truncal acne, identifying its characteristics and exploring assessment methods and management of truncal acne; The study examines the causes and contributing factors of truncal acne by analyzing the skin characteristics and acne phenotypes of the trunk area. It also evaluates the existing methods for assessing the severity of truncal acne; Trunk sebum secretion and pH levels are lower than those of the face, while the degree of microbial imbalance is greater. Variability in androgen levels and gender differences also influence truncal acne. Additionally, contact with certain materials exacerbates acne outbreaks on the trunk. The study highlights the advantages, disadvantages, mechanisms of action, and specific targets of each product. This paper provides insights for future research and practical approaches to truncal acne management, assisting in selecting effective products for managing truncal acne.
