If you've ever looked in the mirror or caught a glimpse of yourself in a photo and thought, "Where did my jawline go?" — you’re not alone. According to board-certified dermatologist Dr. Stefani Kappel, jawline definition is one of the most common concerns her patients bring up. Whether it’s due to genetics, aging, weight changes, or just camera angles catching you off guard, many of us want a more sculpted, contoured look.
✨ Good news: there’s a lot you can do about it.
And Dr. Kappel breaks it all down in her latest YouTube video—no fluff, no sponsorships, just smart, honest skincare insights from nearly two decades of experience.
Why Jawline Contouring Is So Popular Right Now
Our jawlines do more than hold our faces up—they frame them. A defined jawline can make your features appear sharper, more youthful, and even slimmer. But sometimes, the line between your face and neck starts to blur. In Dr. Kappel’s words, “It becomes one continuous unit.” And no, it’s not just you.
From aging and loss of collagen to stubborn fat under the chin (a.k.a. submental fullness), there are countless reasons your jawline might lose its edge. But don’t worry—there are just as many solutions.
Top Treatments for Jawline Definition (As Explained by Dr. Kappel)
💉 Kybella (Deoxycholic Acid)
An FDA-approved injectable that melts submental fat (aka double chin). Dr. Kappel shares her personal experience with KyellA and how it helped contour her own jawline at age 41. The key takeaway? It works—if you're the right candidate.
👉 But watch out for side effects like temporary burning and potential laxity post-treatment. The video covers how to manage that.
🧖♀️ Gua Sha, Facial Massage & Lymphatic Drainage
Great for younger patients or beginners. These at-home techniques can stimulate circulation and reduce fluid retention—but beware: too much of a good thing may cause creasing or lines over time. Dr. Kappel dives into how to use them safely and who should skip them.
💉 Botox: The Nefertiti Lift
A simple 20-unit injection technique that relaxes the downward-pulling muscles of the neck, allowing the upward ones to do their thing. The result? A sharper, more lifted jawline without surgery. Dr. Kappel even does this one on herself!
🔥 Skin-Tightening Devices
From Thermage (Dr. Kappel’s favorite) to micro-focused ultrasound, energy-based treatments offer non-invasive tightening that works wonders when used strategically. She explains why lasers alone won’t cut it—and what tech really delivers.
💀 Jawline Fillers
Fillers like Volux by Allergan are formulated specifically for jawline contour. Think of them like support beams restoring the structure lost over time. Dr. Kappel shares how she approaches filler conservatively for natural results—not the puffy, overdone look.
🧬 Ellacor(Micro Coring Technology)
One of the most exciting FDA-approved innovations for skin laxity. It works like a mini facelift—no scalpel required. The catch? It’s only right for certain skin types and takes multiple sessions. She walks you through what to expect.
What About Surgery, CoolSculpting, or Mewing?
Dr. Kappel also discusses surgical options like liposuction and face/neck lifts—and why she’s cautious with them. From potential nerve damage to paradoxical fat growth, she breaks down the risks you rarely hear about.
She even touches on trending techniques like mewing (popular with TikTok teens) and at-home microcurrent devices. Some work temporarily, some not at all. She gives you the science behind each so you can make the right decision for your face.
Bottom Line: There’s No One-Size-Fits-All Solution
The secret to jawline contouring? It depends on YOU.
Your age, skin quality, facial anatomy, pain tolerance, and goals all matter.
In her signature warm, honest style, Dr. Kappel says it best:
“The art of medicine is knowing how much to give, how frequently, and to whom.”
