Redefining the Jawline: An Approach Tailored to What Is Affecting Its Definition
A well-defined jawline contributes to facial proportions and the way the profile is shaped. For both women and men, the goal can be very different: adding more structure to the lower face, improving chin projection, softening the appearance of jowls, or simply restoring a contour that has become less defined over time.
But there is no single reason why a jawline may lose definition. The structure of the chin and jaw, facial volume distribution, skin laxity, masseter development, and fat beneath the chin can all play a role. Significant weight loss can also change facial volume relatively quickly, making some of these changes more noticeable.
Why Is Your Jawline Less Defined?
Before considering treatment, it is important to understand what is actually affecting the contour of the lower face.
A Less Projected Chin or Jaw
A less projected chin or less prominent jaw structure can affect the profile and make the jawline appear less defined, even when the skin remains firm.
Jowls or Skin Laxity
Jowls and skin laxity gradually develop as the tissues lose some of their support. As this happens, the once clearer line between the face and neck can become less defined.
More Developed Masseter Muscles
Developed masseter muscles can add width to the lower face. It is particularly important to distinguish this from skin laxity or changes in facial volume, as the treatment approach is completely different.
Fat Beneath the Chin
Fat beneath the chin can obscure the jawline and change the profile, regardless of overall body weight.
Significant Weight Loss
Significant or rapid weight loss can change facial volume. A reduction in fat through the cheeks and lower face can make skin laxity, jowls, or loss of support more noticeable. This is sometimes referred to as “Ozempic face,” but it can occur following significant weight loss regardless of the method.
Treatments to Help Define the Jawline
Dermal Fillers
When a lack of definition is primarily related to facial structure, hyaluronic acid dermal fillers can be used in areas such as the chin or jawline. Strategically placed injections can help improve projection, angles, and balance across the lower face without necessarily adding significant volume, including for men looking for a more structured jawline.
Biostimulators
Biostimulators such as Sculptra, Radiesse, and HArmonyCa may be considered when loss of definition is accompanied by reduced tissue support. Their action includes the gradual stimulation of collagen, although they work differently depending on the product, with some also providing more immediate structural support. The choice therefore depends on your anatomy, tissue quality, and treatment goals.
Masseter Injections
When developed masseter muscles contribute to a wider lower face, muscle relaxant injections can temporarily reduce their activity. Over time, the muscle may gradually decrease in volume, which can change the proportions of the jaw. This approach therefore targets a specific muscular cause rather than a lack of structure or skin laxity.
HIFU
HIFU uses focused ultrasound to deliver energy at precise depths beneath the skin and progressively stimulate collagen production. Technologies such as Ultherapy use this principle to target deeper tissues that contribute to facial support. This approach may be considered when laxity contributes to a less defined jawline and lower facial contour.
RF Microneedling
RF microneedling combines fine microchannels with radiofrequency energy delivered into the dermis to stimulate collagen and elastin production. On the lower face, it may be considered when loss of definition is accompanied by laxity and changes in skin texture or quality, with a different action from ultrasound technologies that target deeper structures.
Radiofrequency
Radiofrequency treatments use controlled heat to stimulate collagen production and progressively improve skin firmness. Depending on the technology selected, they can be used along the jawline and neck when skin laxity contributes to a less defined lower facial contour. They may be used on their own or integrated into a treatment plan combining different approaches.
Double Chin
When fat beneath the chin obscures the jawline, treatments that directly target this volume may be considered. Belkyra uses deoxycholic acid injections, while CoolSculpting uses cryolipolysis to reduce fat cells in the submental area. The choice depends on factors such as the amount of fat, skin quality, and whether laxity also needs to be addressed.
A Treatment Plan That Looks at the Whole Picture
Your jawline is unique, and your treatment plan should be too. One advantage of a large network of clinics is access to collective expertise: teams share knowledge, experience, and clinical perspectives across the network. This gives you an approach informed by expertise that extends beyond a single clinic or a single treatment.
This expertise also allows your face to be considered as a whole, with a personalized treatment plan built around your anatomy, your goals, and what is actually affecting your jawline definition. Injectables, in-clinic technologies, and skincare can be combined when appropriate to address different factors and allow your plan to evolve with your needs over time.

HArmonyCa: A Dual-Action Injectable, Delivered by Experts You Can Trust
Have you noticed your jawline looking a little softer, or your cheeks a little less defined than they used to be? This is one of the most common concerns we hear at our clinics, and it is a normal part of how skin changes with time. As we get older, our skin slowly makes less collagen, the protein that keeps it firm and springy. HArmonyCa is a treatment designed to help with exactly this. It restores support where the skin has lost it, and it encourages your skin to rebuild its own collagen over time.
Radiesse vs. Sculptra: What Really Makes Them Different
Aging isn’t just about lines or volume loss. It’s about how your skin slowly forgets to renew itself. Over time, the signals that once told your cells to rebuild, repair, and stay firm begin to fade. What if we could remind your skin how to act young again? That’s the idea behind today’s most advanced biostimulators: Radiesse and Sculptra.
Facelift Without Surgery
As we age, it’s common to notice our facial skin losing its firmness and vitality. This natural process is largely due to a decrease in collagen production, which can lead to a tired, sagging appearance. Traditionally, surgical facelifts have been the go-to solution for those seeking a significant lift, yet the invasive nature of surgery and the downtime required are factors many wish to avoid. Fortunately, we offers a breakthrough solution that allows you to achieve a facelift without surgery—introducing Ultherapy, a non-invasive treatment that lifts and tightens the skin without incisions or needles.
How to Get Rid of Double Chin Fat Without Surgery
Also known as submental fat, a double chin occurs when several layers of fat form on the chin, causing a loss of angle and definition between the lower face and the neck. Many people, regardless of gender, feel self-conscious about their double chin. Although this type of fat is commonly associated with excess weight, it can also be genetic or hormonal. Unfortunately, double chins are often difficult to eliminate naturally through diet and exercise alone.
