title: Facial Blanching After Cosmetic Botulinum Toxin Injection: Case Series.
abstract: Case 1 A 32-year-old woman was treated for the first time with onabotulinumtoxinA (BoNT), receiving 10 units in her forehead and 20 units in her glabella. She reported no history of skin disease and had a very active lifestyle. She first noticed blanching while doing a group workout and a friend inquired if she had "hives" on her forehead (Figure 1). She continued to note the blanching during workouts 5 months after injection. Each episode lasted 30 minutes to 2 hours. There were no associated symptoms with the blanching other than minor embarrassment. Given her active lifestyle and frequent blanching, she has elected not to receive further injections.
