Neck bands form as the platysma muscle contracts and pulls the skin vertically, while horizontal “necklace lines” are creases from repetitive movement and loss of collagen. Skin laxity and thinning accentuate their visibility with age.

First-line care uses neuromodulators (Botox, Dysport, Xeomin, Daxxify) to relax the platysma and smooth vertical banding. Dermal fillers (Juvéderm, Restylane, RHA, Radiesse) may be placed to soften horizontal lines.

Adults noticing vertical platysma bands or horizontal necklace lines who want a smoother, firmer neck without surgery.
