Hidradenitis suppurativa (HS), also known as acne inversa (AI), is a chronic, recurrent inflammatory disease of the pilosebaceous unit that primarily affects intertriginous areas and is characterized by recurrent, painful, deep-seated inflammatory lesions. The pathogenesis of HS/AI is multifactorial, involving genetic susceptibility, immune dysregulation, microbial imbalance, and obesity. HS/AI remains difficult to manage, and current treatment aims to reduce the frequency and duration of flares, decrease disease severity, and improve quality of life. Treatment selection should be guided by disease severity and activity. Pharmacologic therapies include antibiotics, biologics, small-molecule agents, retinoids, and immunosuppressants, while adjunctive approaches include surgical interventions and energy-based therapies. This updated consensus aims to standardize the diagnosis and management of HS/AI in China and to improve clinical practice by providing a stepwise, multidisciplinary treatment framework in which interventions are stratified according to disease severity and recommendation strength. Recommendation strength was determined by expert voting: an agreement rate of ≥ 85.0% = Should be recommended, ≥ 75.0% to < 85.0% = Could be recommended, ≥ 50.0% to < 75.0% = May be considered, and < 50.0% = No consensus reached. Key recommendations reaching the ≥ 85.0% agreement threshold included severity-based treatment selection, topical clindamycin for mild localized disease, systemic tetracyclines for mild-to-moderate HS/AI, and biologics, including adalimumab, secukinumab, and bimekizumab, for moderate-to-severe disease. The consensus has been registered on the International Practice Guidelines Registry Platform (No: PREPARE-2025CN1964).
