The patient developed burning swollen lesions on the left forehead four days after receiving BTX injections. Physical examination revealed papules and erosions in a dermatomal distribution. He was diagnosed with HZ and promptly treated with oral acyclovir. The lesions resolved within two weeks without complications. Previous literature reports a few similar HZ outbreaks following aesthetic treatments with BTX injections. The exact mechanism triggering varicella reactivation in these cases remains unclear. Prompt diagnosis and treatment of HZ are crucial in order to minimize outbreak duration and reduce complications. Physicians should maintain awareness of HZ as a potential complication following BTX injections.Keywords: botulinum toxin, complications, herpes zoster, shingles
