A Dermatologist's Guide to Nonsurgical Rejuvenation of the Neck and Jawline

Rejuvenation of the neck and jawline is an increasing concern for patients seeing dermatologists and aesthetic providers. This review aims to provide a comprehensive narrative review of evidence on nonsurgical neck and jawline rejuvenation techniques.

Multiple databases (Ovid MEDLINE, Embase, and Web of Science) were queried with the assistance of 2 health science librarians. Searches were based on a combination of keyword terms related to nonsurgical modalities of neck and jawline rejuvenation.

Our search identified 1,225 studies, with 451 relevant to review. Injectable options include deoxycholic acid for fat reduction; neuromodulators to smooth dynamic wrinkles, sharpen the jawline, and reduce lower face volume; fillers to address volume loss, enhance contours, and improve skin quality; and thread lifts to improve skin elasticity. Energy-based options include ablative and nonablative lasers, helium plasma devices, plasma exeresis, radiofrequency (RF), cryolipolysis, and ultrasound to address skin laxity and submental fullness and to promote collagen production. Mechanical stimulation options include microneedling, RF microneedling, and microcoring to stimulate elastin synthesis. Office-based liposuction is also an effective modality for submental fullness.

As a hybrid narrative review, this study is limited by the lack of formal quality assessment of individual studies but strengthened by systematic inclusion criteria.

Improved cosmetic outcomes with overall low rates of complications have been reported with neck and jawline rejuvenation therapies discussed in this review. Appropriate patient selection and managing expectations are paramount when considering treatment plans.
