Is It Possible/beneficial to Use Botox for Neck Wrinkles?

Botox has beneficial effects in reducing appearance of platysma bands in the neck. This is an off label use but has been demonstrated to have efficacy. If the condition of the neck involves significant sagging or skin laxity, then neck lift would be the treatment of choice.

Botox does a reasonable, albeit temporary job on the vertical bands in the neck known as platysmal bands. It has very little effect on horizontal lines in the neck.

Botulinum toxin works best in active muscles of facial expression rather than static lines from chronic sun exposure or loss of elasticity. Therefore the muscles of the neck which animate with facial activity will see the best response to treatment. This consists primarily of the vertical neck bands ("turkey gobbler")
