Jaw and chin feminization reshapes the lower third of the face into a softer, more tapered, more oval contour. It usually combines jaw contouring, reducing the width and angle of the mandible and sometimes slimming the masseter muscle, with a genioplasty that narrows and reshapes the chin, often reducing its height and forward or square projection. Together they replace a wider, more angular lower face with the smoother, more V-shaped line associated with feminine features. The incisions are usually made inside the mouth, so there is no visible external scar. In Thailand these are performed by facial feminization surgeons, often alongside other facial procedures.
What the lower face signals
The lower third of the face carries a lot of gendered information. A wider, squarer jaw with a defined angle, a taller or more projected chin, and greater bony width all read as masculine, partly because testosterone builds up the mandible and chin during puberty. Feminizing the lower face means softening and tapering these features so the jawline curves into a smoother, more V-shaped or oval outline.
This is bone and muscle work, so it addresses the parts of the lower face that hormones and skincare cannot change. It is often done alongside the upper-face procedures, because the face is judged as a whole; a softened forehead sits more naturally above a tapered jaw. The goal is harmony and a natural result, not the narrowest possible jaw.
For many people the lower face is a key part of being read correctly, which is why jaw and chin work is a common component of a fuller feminization plan.
Jaw contouring
Jaw contouring, sometimes called mandibular angle reduction or jaw shaving, reshapes the back part of the lower jaw. The surgeon reduces the flare and prominence of the jaw angle and can shave down the width and thickness of the mandible along its border, so the jawline curves more smoothly rather than turning a sharp, wide corner. The result is a softer transition from the ear down to the chin.
How much can be reduced depends on your anatomy, including the position of the nerve that runs through the jaw, which the surgeon protects. A careful assessment, usually with imaging, guides how much reduction is safe and how to keep the result balanced and natural rather than over-reduced. Taking away too much can look unnatural or leave the face looking gaunt, so restraint matters as much as reduction.
Chin reshaping (genioplasty)
A genioplasty reshapes the chin, and for feminization this usually means narrowing it and, where needed, reducing its height and its forward or square projection. A masculine chin is often taller, wider and more square or forward-set; a feminine chin is generally shorter, narrower and more tapered or slightly pointed.
The surgeon can reshape the chin bone to narrow and shorten it, and can adjust projection, tailoring the change to balance with the jaw and the rest of the face. Because the chin and jaw work together to create the lower-face outline, they are usually planned as a pair, and reshaping the chin is often what completes the tapered, V-shaped line that jaw contouring begins.
Width and the masseter muscle
Lower-face width is not only bone. The masseter, the strong chewing muscle over the jaw angle, can add to a wide or square appearance, especially if it is bulky. Where the muscle is a significant contributor, its bulk can be reduced surgically at the same time as bony contouring, or in some cases softened non-surgically with muscle-relaxing injections.
Assessing how much of the width is bone and how much is muscle is part of the surgeon’s plan, because reducing bone alone will not fully taper a face where the muscle is the main issue, and vice versa. Addressing both where needed is what gives a smooth, even result. Your surgeon will explain which applies to you at consultation.
The procedure and scars
Jaw and chin feminization is done under general anaesthetic. The great advantage for scarring is that the incisions are usually made inside the mouth, along the gum line, so the bone is reached without any cut on the skin and there is no visible external scar. The surgeon reshapes the jaw and chin as planned and closes the incisions internally.
Depending on how much is combined, the operation commonly takes a few hours. Most people stay one to two nights so the team can monitor early swelling before discharge to their accommodation. You will usually wear a supportive dressing or garment around the jaw at first, and eat a soft diet for a period while the internal incisions heal. Discomfort is generally described as swelling, tightness and pressure rather than sharp pain, and is well controlled with medication.
Jaw and chin recovery timeline
Lower-face surgery swells more than most facial procedures, and knowing the pattern makes the early stage less worrying. This is a general guide; your surgeon’s instructions come first.
- First week. Swelling is significant and peaks in the first days, along the jaw, chin and often the neck. A soft diet, sleeping propped up and any supportive garment all help. Internal stitches begin to settle.
- Weeks two to four. The most obvious swelling comes down and many people feel comfortable being seen, though the jawline still looks fuller than the final result. Numbness of the chin and lower lip is common and expected.
- Weeks four to eight. Swelling continues to settle and the contour starts to emerge. Most people are back to desk work within a couple of weeks and resume gentle exercise around this point once cleared.
- Three to six months and beyond. The last, deeper swelling resolves and the final tapered contour settles in. Numbness of the chin and lip recovers gradually as nerves regenerate.
How jaw and chin work fits a facial plan
Because the face reads as a whole, jaw and chin feminization is often combined with upper-face procedures such as forehead reduction, a brow lift, rhinoplasty and a tracheal shave, so the whole face is brought into balance in one plan. Combining procedures in a single anaesthetic also means one recovery rather than several.
Which combination is right depends entirely on your features and priorities, and a good surgeon may advise doing less rather than more where a subtle change suits your face better. Our overview of what facial feminization surgery is explains how a full plan is assembled around the individual face.
What results look like
The result of jaw and chin feminization is a lower face that reads as smoother and more tapered, with the jawline curving into a softer line and the chin narrower and better balanced with it. Because the change is to the underlying bone, it is permanent once healing is complete. For many people it is the piece that resolves a lingering sense that the lower face looked heavy or square, and it tends to work quietly, by removing a masculine cue rather than adding an obvious one.
It is worth setting expectations around subtlety and swelling. The final contour only shows once the deeper swelling has fully settled over some months, so judging the result too early can be misleading. And a natural outcome is usually a moderate one: the aim is a balanced lower face in proportion with your features, not the narrowest possible jaw, which can look unnatural or gaunt. A good surgeon plans for balance and will show you what is realistic for your anatomy.
Risks and choosing a surgeon
Jaw and chin contouring is bone surgery in an area with an important nerve, the one that supplies sensation to the lower lip and chin, so surgeon experience matters a great deal. The main risks are temporary numbness of the lip and chin (which usually recovers), significant early swelling, and, in the wrong hands, over-reduction that can look unnatural or leave the face gaunt. Careful planning, usually with imaging, is how a good surgeon protects the nerve and keeps the reduction safe and balanced.
Worth asking: how many of these procedures the surgeon performs, how they plan around the nerve, how much reduction they consider safe for your anatomy, and how they keep the jaw and chin balanced with the rest of the face. A surgeon who favours a natural, proportionate result over the most dramatic possible reduction is the one to trust. Surgeons generally work within the WPATH Standards of Care (SOC-8) alongside each hospital’s assessment. We only coordinate care with vetted hospitals, and make sure you can put your questions to the surgeon before committing.
Jaw and chin surgery in Thailand
Thailand is a well-established destination for facial feminization, with high-volume hospitals and surgeons who perform jaw and chin contouring regularly within dedicated FFS programmes. We are a facilitator, not a hospital: we coordinate the surgery your chosen partner hospital provides inside one trip, with recovery-suitable accommodation, transfers, interpreting and aftercare, handled by one team that speaks your language.
Because jaw and chin work is usually part of a wider facial plan, cost depends on the combination of procedures. You can see indicative guide prices on our pricing page, read our guide to FFS cost, and see the full picture on our FFS in Thailand page. Prices are indicative and confirmed only after the surgeon reviews your case.
