When it comes to facial aesthetics, the jawline and neck have officially taken center stage. A defined jawline, a smooth neckline, and the absence of a “double chin” are now among the top requests we see at Thomas Dermatology. The good news? You don’t need surgery to achieve noticeable improvements. Thanks to advanced injectables and skin-tightening technologies, there are non-invasive solutions that actually work.

Here’s your guide to the most effective non-surgical options for jawline and neck rejuvenation—and how to know which treatment might be right for you.

Biostimulators: Sculptra & Radiesse

If your main concern is skin laxity (loose or sagging skin) along the jawline or neck, biostimulatory fillers are game changers. Unlike hyaluronic acid fillers that simply add volume, Sculptra and Radiesse work by stimulating your body’s own collagen production.

• Sculptra: Made from poly-L-lactic acid, Sculptra gradually restores structure and firmness. It’s perfect for subtle, natural improvements over time.
• Radiesse: A calcium-based biostimulator that adds an immediate lift while also triggering collagen growth. It’s great for sharper definition in the jawline.

Who’s a candidate? Patients with mild to moderate skin laxity who want gradual, long-lasting tightening without a “filled” look.

Neuromodulators for Neck Bands

Those vertical lines that run down your neck—known as platysmal bands—can make the area look older and more tense. Neuromodulators like Botox®, Dysport®, or Xeomin® can relax these overactive muscles, softening the appearance of bands and creating a smoother neck contour.

Who’s a candidate? Anyone noticing visible “stringy” lines or bands on their neck when speaking, grimacing, or swallowing. Results are temporary (3–4 months) but highly effective.

Deoxycholic Acid for Submental Fullness (Double Chin)

Stubborn fat under the chin, or “submental fullness,” is one of the most common jawline concerns. Deoxycholic acid injections (FDA-approved as Kybella®) permanently destroy fat cells in the treated area, reducing fullness and improving jawline definition.

Who’s a candidate? Patients with mild to moderate fat under the chin who want a sharper profile without liposuction. Best for those with good skin elasticity, since fat reduction doesn’t address loose skin.

RF Microneedling: MediRAF for Tightening

For skin that feels crepey, loose, or less firm around the jaw and neck, radiofrequency (RF) microneedling—like MediRAF—offers advanced tightening. This treatment uses tiny microneedles to deliver radiofrequency energy deep into the skin, stimulating collagen and elastin while improving texture.

Who’s a candidate? Anyone dealing with early sagging, mild jowls, or skin laxity who wants a non-surgical “lift.” It’s also great for patients who want overall skin rejuvenation in addition to tightening.

Combination Approaches: The Best Results Come from Personalization

At Thomas Dermatology, we often recommend a combination of these treatments. For example, biostimulators can firm the skin, while deoxycholic acid reduces fat, and RF microneedling tightens what’s left behind. Neuromodulators can be added to smooth vertical neck bands.

Because every face and neck are unique, the best plan depends on your anatomy, goals, and lifestyle. The beauty of non-surgical treatments is that they can be customized and layered for maximum results—with little to no downtime.

The Takeaway: Non-Surgical Jawline & Neck Rejuvenation

Defined jawlines and youthful necks are more achievable than ever—without going under the knife. With biostimulators, neuromodulators, fat-dissolving injections, and RF microneedling, you have powerful tools to refresh your look safely and effectively.

If you’ve been considering jawline or neck rejuvenation, fall and winter are excellent times to start treatments so you can see full results by spring. Schedule a consultation with the expert team at Thomas Dermatology to find out which options are right for you.
