Analysis of Side Effects from Cosmetic Procedures with Botulinum Toxin

Background and ObjectivesThe use of botulinum toxin in cosmetic procedures is widespread.While the side effects of the procedure and problems with resistance due to excessive use are being discussed, studies of clinical patterns of botulinum toxin use and side effects associated therewith are lacking. Materials and MethodsIn this study, clinical usage patterns for botulinum toxin were analyzed through a web-based, real-time survey conducted at the Korean Association for Laser Dermatology And Trichology Fall Academic Conference held in December 2018.A questionnaire was administered to assess different types and locations of side effects experienced and the frequencies thereof. ResultsThe most common side effects that the clinicians reportedly encountered during botulinum toxin treatment were bruising and Mephisto sign from overcorrection.The most common site of side effects was the upper part of the face. ConclusionThis study highlights the need to raise awareness of the importance of education on the anatomy of the upper part of the face, where side effects for cosmetic procedures with botulinum toxin are most common, to reduce the possibility thereof.
