On the jawline and the lower face contour, Kobido — a Japanese facial massage practised manually — doesn't mechanically "lift" anything: it helps a precise release of the muscles and the tension they hold. In practice, I relax the masseter (the jaw muscle, which is often tight), I work through the tensions that travel from the lower face down to the base of the skull, and I wake up the muscle areas that support the lower face — without practising a proper neck massage. The result isn't a lifting effect: it's a face that looks more settled, with a jawline that appears more clearly defined, because it has let go and regained tone.

Why the jawline seems to "soften" over time
Before talking about what Kobido does, it's worth understanding why the lower face contour can start to look less defined. Several factors combine.
A gradual loss of tone in the facial expression muscles. The face has around forty small, fine muscles that insert directly into the skin. With time, stress and repeated tension, these muscles lose tone — like any under-used muscle — and the area starts to look less "held". The anatomy of these facial muscles is well documented in clinical references: most are very fine, sit just under the skin, and are innervated by the facial nerve.
Excessive tone in other muscles, particularly the masseter. The jaw muscle is often in the opposite situation: over-recruited (jaw clenching, stress, sustained concentration), it can become hypertonic and visually weigh on the jawline. It's a paradox: a softened jawline is the result of both muscles that have lost tone and muscles that have too much.
Tension in the base of the skull, the back of the head and the trapezius. Anything that tightens below the face can visually affect the jaw contour and create a downward pull. This is very clear in the studio.
The underlying structure and the skin itself also play a part, but these are areas where Kobido has limited reach.
The muscles I work on for the jawline
In practice, the manual work on the jawline involves several muscles, each with its own role.
The masseter is the powerful muscle that closes the jaw — you can feel it by clenching your teeth. Clinically, it's described as a thick, quadrangular muscle that runs from the zygomatic arch to the angle of the mandible, and it's one of the most frequently overworked muscles of the face. When it stays too tight (which is very common), it weighs on the jaw contour. My work here is essentially one of releasing: I knead it, mobilise it, ease the built-up tension. It's one of the most recognisable manoeuvres of a Kobido session.
The platysma. The platysma area, which connects the lower face to the neck, can influence the appearance of the jaw contour. In my practice, I stay on the upper part of the lower face, without massaging the neck proper.
The supporting muscles. Several facial expression muscles contribute to holding the lower face (risorius, zygomaticus major, fibres of the buccinator). Often under-used, they can be reawakened by precise manual work on the muscle areas that take part in this support.
The fascia of the area. Muscles don't work in isolation: they are connected by fascia — the fine envelopes that surround them. A significant part of the work is releasing these, since they can stiffen over time and limit the mobility of the face.
What I actually do during the session
On the jaw and lower face area, my work takes about ten to fifteen minutes per session, in several passes.
Deep upward effleurages from the chin towards the ears, along the jawline. These stimulate microcirculation, help the area feel lighter, and immediately give the face a more settled visual orientation.
Kneading on the masseter. I locate the muscle precisely (sometimes asking you to clench your teeth briefly so I can find it), then I knead it in depth. This manoeuvre can feel a little intense at first — many of my clients discover at this moment how tight their masseter actually was.
Acupressure points along the jaw and temples, which help regulate tension across the whole area.
Work on the base of the skull (occiput) and the top of the neck. Without going down into the neck, I work this hinge area that is almost always involved in jaw and lower-face tension.
What I observe
When I work the jaw area, the clearest effect my clients describe to me isn't visual — it's first a sensation: "It feels as if the jaw has set down something it was holding." That muscular release is what shows afterwards. The face looks more open, more settled, because it has let go of what it was carrying.
The role of posture and cervical tension
One point that often surprises my clients: working the jawline largely passes through what sits just below the face. The back of the head, the base of the skull, the trapezius: all of this visually influences the jaw contour when it's tight. On faces that are very tense in these areas — often people whose posture sits forward — a first session sometimes produces a more visible effect on the lower-face line than purely facial work would have given.
I don't turn into a physiotherapist for the length of the session. But the work on the occiput and the upper neck, which are an integral part of my practice, often brings this knock-on benefit. To go further on cervical tension itself, it's a physiotherapist or osteopath you'd want to see.
What this work can do — and what it can't
What this work can do: support a more clearly drawn jawline, a less clenched jaw, a cleaner transition between the cheek and the neck, a face that looks more settled. For people who frequently clench their teeth, work on the masseter can also support a sense of release. It doesn't replace dental or medical care for established bruxism; it simply works on a tension pattern that is often felt around the lower face.
What it can't do: replace a structural lifting effect. Kobido doesn't mechanically "lift" the jaw — it supports its tone and releases what weighs around it. On long-standing slackening, the result is more modest; aesthetic medicine can offer more marked effects if that's what's being sought. If your concern is significant sagging or a fast structural result, I explain the difference between manual treatment and medical procedures in more detail in my article on Kobido and aesthetic medicine.
Work on the jawline calls for consistency: a single session brings a felt difference on the jaw and the level of relaxation, but it's through a course (at least five sessions) and then regular maintenance that the effects take shape and last over time.

Frequently asked questions about the muscular work on the jawline
Can Kobido help the jawline look more clearly drawn?
Kobido can support a more clearly drawn jawline by working the muscles involved (masseter, platysma, supporting muscles) and taking into account the cervical tension that visually influences the area. The result isn't a mechanical lifting effect but a face that looks more settled because it has let go. This calls for a course of sessions and then regular maintenance.
Why does Kobido work so much on the masseter?
The masseter — the muscle that closes the jaw — is very often hypertonic, because of stress, nighttime teeth clenching, or sustained concentration. When it's too tight, it weighs on the jawline and visually pulls the lower face downward. Releasing it through deep kneading is one of the key manoeuvres of working the jaw contour in Kobido.
How many sessions to see a difference on the jawline?
From the very first session, many clients feel a less clenched jaw and a more relaxed area. For a difference that's visible and lasts, I recommend a course of five to ten closely spaced sessions (one a week), followed by regular maintenance. The jawline is one of the areas that calls for the most consistency.
Does Kobido on the jaw area hurt?
Working the masseter can feel a little intense at first, especially when the muscle is very tight — a useful intensity, comparable to manual work on a contracted area of the back. I always adjust the pressure to your feedback, and the sensation eases session after session.
