ABSTRACT
This chapter discusses the use of BoNT-A in dermatology for the treatment of painful conditions including Raynaud's phenomenon, defined as an episodic digital asphyxia caused by vasospasm of the digital arteries triggered by cold exposure or stress. Others include post herpetic neuralgia, headache, reflex sympathetic dystrophy (or complex regional pain syndrome), depression, and a variety of other conditions. Novel dermatologic therapeutic applications include targeting hypersecretion and pain. Lastly, BoNT-A has a long history of being used to improve posture in a variety of conditions. In the cosmetic surgery sphere, the use of Botox to improve upper thoracic posture is a method aimed at improving the presentation of the female breasts, commonly known as a “breast lift”.
