Persistent Erythema Ab Igne Occurring After Low-Level Laser Therapy for Lipolysis

摘要： Erythema ab igne (EAI) is a chronic skin condition characterized by blanchable, reticular, erythematous, hyperpigmented macules and patches and can develop from prolonged exposure to infrared radiation in close proximity. It is often asymptomatic; however, some patients report mild skin sensitivity and pruritus. Low-level laser therapy (LLLT) uses red light for non-invasive body contouring.1 Current literature suggests that LLLT provides statistically significant fat reduction in the absence of serious adverse events.2 Although EAI after prolonged electronic device use has been reported, it is not considered an adverse effect of LLLT. Here, we report a case of persistent EAI post-LLLT for lipolysis and body contouring.
