Abstract: 【Abstract】 Acne sequelae primarily include post-acne erythema, post-acne hyperpigmentation, and post-acne scarring. These residual cutaneous lesions persist in a substantial proportion of patients following the resolution of active acne and are attributable to factors such as inflammatory responses and inappropriate manipulation of lesions. Acne sequelae are highly prevalent, impose a considerable disease burden, and exert a profound negative impact on patients′ mental health and quality of life. Although a wide range of therapeutic modalities is currently available and new treatment technologies continue to emerge, substantial variability exists in treatment efficacy, and clinical decision-making remains highly heterogeneous. To promote the standardization of the diagnosis, prevention, and management of acne sequelae, the Acne Study Group of China Dermatologist Association, the Acne Study Group of Chinese Dermatovenerology Society of Integrative Medicine, the Acne Group of Chinese Society of Dermatology, and the Dermatology Committee of Chinese Non-government Medical Institutions Association organized an expert panel to develop this consensus through a comprehensive review of recently published Chinese and international literature, with consideration of current clinical practice in China. This consensus is intended to provide clinical guidance for clinicians in the assessment, prevention, and treatment of acne sequelae.
