Facial Cosmetic Therapy Use Among Patients With Systemic Sclerosis: An Australian Cohort Study
Arthritis Care &Research, EarlyView.Objective Systemic sclerosis (SSc) is associated with numerous facial manifestations for which patients may engage in cosmetic therapies. It is unclear how patients with SSc use these therapies. This study sought to characterize patient engagement and experiences with cosmetic therapies for SSc‐related and non‐SSc–related facial changes.
