About
This single blinded randomized pilot study was performed on 21 Caucasian females to determine if injections through follicular openings were less painful than traditional injections for cosmetic botulinum toxin type A injections.
Full description
Objective: To investigate whether injection of botulinum toxin type A is less painful if performed through follicular openings versus traditional non-specific approach.
Design: Prospective, randomized, single-blinded study.
Setting: Academic dermatology department.
Patients: A volunteer sample of twenty female patients aged 25-55 who had no prior history of botulinum toxin injection.
Intervention: Each patient received six randomized injections of botulinum toxin type A (Botox® Allergan). Two injections into the procerus muscle and two into each corrugator muscle. Three of the injections were performed through follicular openings and three were performed traditionally.
Main Outcome Measure: Patient discomfort on a 1-10 scale and direct comparison between the two injection techniques.
