Jawline slimming in Winchester
A softer jaw, without surgery.
Reshaping the jaw
from the inside.
Jawline slimming uses a muscle-relaxing injectable administered directly into the masseter, the large muscle responsible for chewing, which sits at the angle of the jaw. When this muscle is overactive or naturally large, it creates a wide, square jaw shape that can make the lower face appear heavy or masculine. By relaxing the masseter, the muscle gradually reduces in size over several weeks, slimming and softening the jawline without any surgery, incisions, or recovery time.
A more refined jaw changes the entire balance of the face. For many patients it is one of the most quietly transformative treatments we offer.

Our speciality.
The masseter is the muscle dentists work with every single day. Our clinicians understand its anatomy, its function, its relationship to the bite and jaw joint, and its variation between patients in a way that extends well beyond standard aesthetics training.
A slimmer, more refined jaw
For patients who feel their jawline is too wide, too square, or too heavy, masseter treatment offers a genuinely transformative result without any surgery. As the muscle gradually reduces in size over six to eight weeks, the jaw softens and narrows, creating a more oval and balanced facial profile. The result is subtle and progressive rather than sudden, which makes it appear entirely natural to those around you.
A more balanced facial profile
The width of the lower face has a significant influence on overall facial harmony. When the masseter is large, it can create a heavy or angular appearance that makes the face look wider than it is long. As the muscle reduces, the face naturally takes on a more oval, tapered shape, improving the relationship between the upper and lower face and creating a more balanced, refined overall appearance.
No surgery, no downtime
Jawline slimming is a simple injectable treatment that takes around thirty minutes. There are no incisions, no anaesthetic required, and no recovery period afterwards. Some mild tenderness at the injection sites for a day or two is normal, but most patients return to their usual activities immediately. The full result develops gradually over six to eight weeks as the masseter muscle reduces in size.
Results that complement other treatments
Jawline slimming works particularly well in combination with other facial aesthetic treatments. A slimmer jaw pairs naturally with chin or cheek filler to create a more sculpted overall profile, and can make the results of other treatments appear more harmonious. At your consultation we always consider the face as a whole, and if a combined approach would serve you better, we will say so.

Things people
often wonder.
Everything you might want to know before your jawline slimming consultation. Still have a question? We are always happy to help.
No. The masseter is a powerful muscle and the doses used for cosmetic slimming reduce its bulk and force without affecting its basic function. You will still be able to chew normally throughout the treatment period. Some patients notice mild tenderness or a slightly tired sensation in the jaw when chewing very tough foods in the first few days after treatment, but this is temporary and uncommon. Our dental clinicians are uniquely placed to assess and monitor the impact on your bite and jaw function throughout.
Results develop gradually over six to eight weeks as the masseter muscle reduces in size. Unlike anti-wrinkle injections in other areas, the change is progressive rather than immediate, which gives it a very natural appearance. Most patients begin to notice a difference in jaw shape and a reduction in grinding activity from around four to six weeks. Full results are typically visible by eight weeks, which is when we offer a review appointment.
Results typically last between four and six months, after which the muscle gradually regains its activity and size. With regular treatment over time, many patients find that the masseter stays smaller for progressively longer periods, as the muscle adapts to being less active. For patients using the treatment to manage bruxism, maintenance is particularly worthwhile given the protection it offers to the teeth and jaw joint.
Most patients find jawline slimming very comfortable. The masseter is a dense, substantial muscle, so the injection is typically less uncomfortable than in more superficial areas of the face. No anaesthetic is required. You may feel mild pressure or a brief sting at the point of injection, but this passes almost immediately. Some mild tenderness at the injection sites for a day or two is normal and settles without any treatment.
Yes, and combining treatments often produces the most balanced result. A slimmer jaw works particularly well alongside chin or cheek filler, which together create a more sculpted and harmonious facial profile. Many patients also combine jawline slimming with anti-wrinkle injections for a comprehensive facial refresh. We always assess the face as a whole at consultation and will recommend a combined approach if we believe it would serve you better than a single treatment alone.
