title: How to avoid complications when treating hyperdynamic folds and wrinkles.
abstract: Before discussing the complications that might occur in the treatment of hyperdynamic folds and wrinkles, it is important to analyze and define the correct effects and unwanted effects, or even adverse reactions, after administration of botulinum toxin (BTX) for cosmetic indications.
