What are the primary indications for botulinum toxin treatment in the neck area as discussed in the chapter on Neck Bands?

The primary indications for botulinum toxin treatment in the neck area are the reduction of vertical neck bands and submental fullness, which enhances neck contour.

Botulinum toxin treatment in the neck area primarily targets the platysma muscle to reduce vertical neck bands, also known as platysmal bands. These bands are vertical folds that can become more prominent with muscle contraction or aging. By inhibiting the contraction of the platysma muscle, botulinum toxin helps diminish these bands and reduce submental fullness, leading to a more defined neck contour. However, conditions like skin laxity and adiposity are not improved with this treatment.
