    Concern · Lower face descent

    Jowls treatment in London — support first, then softness.

    A jowl is the point where your jawline stops being a clean edge. It is almost never one problem. It is lost bony support, descended fat and a skin envelope that no longer holds — which is why treating only one of the three tends to look like nothing happened, or worse, like something was added.

    We treat jowls with three tools and no machine we do not believe in: structural jawline and pre-jowl filler, PDO threads (fine mono threads and lifting cogs), and Endolaser — laser energy delivered under the skin. Doctor-led at 10 Harley Street since 2007.

    Jowls are treated non-surgically in three ways: structural filler along the jaw angle and pre-jowl sulcus to rebuild lost bony support, barbed cog PDO threads to reposition descended tissue, and Endolaser, which passes a laser fibre beneath the skin to reduce a small volume of fat and contract tissue. Most successful plans combine two of the three.

    Why a jowl forms — the apple analogy

    Think of the face as an apple. The skin of the apple is your skin. The yellow flesh beneath is your fat. When a face looks sunken and heavy at the same time, it is rarely the skin that lost volume — it is the flesh beneath it, and the bone beneath that. The skin is simply left with more surface area than structure to cover.

    Bone

    The jaw and chin resorb with age. The shelf the soft tissue rested on gets smaller, so the tissue slides forward and down.

    Fat

    Deep fat pads deflate while superficial pads descend, gathering just in front of the jawline as a visible pad.

    Skin & ligaments

    Collagen and the retaining ligaments loosen, so nothing holds the descended tissue in position.

    The manual test we use in clinic is simple. If lifting the skin gently upward with a fingertip makes the jowl disappear, the problem is descent and lost support — not excess fat. That single observation usually decides the plan.

    Your treatment options

    Three tools, chosen by anatomy — not by what we happen to own.

    1. Jawline & pre-jowl filler — rebuild the shelf

    Structural-grade hyaluronic acid is placed deep on bone at the jaw angle, along the jaw body and into the pre-jowl sulcus — the small hollow just in front of the jowl that creates most of the shadow. Restoring that hollow is often what makes the jaw read as one continuous line again, without adding bulk to the jowl itself.

    • Best for: early jowling, visible pre-jowl hollow, weak jaw definition
    • Lasts: 15–18 months in this low-movement area
    • Reversible with hyaluronidase if you change your mind
    • From £350 (1ml) · £650 (2ml) · Natural HD Jawline plan £950

    2. PDO threads — mono and cogs — reposition the tissue

    There are two very different threads and the distinction matters. Mono threads are fine and smooth; placed as a mesh they stimulate collagen and improve skin quality and firmness, but they do not lift. Cog threads carry tiny barbs along their length that grip descended tissue and hold it in a higher position while collagen forms around the thread. Cogs are the lifting thread; monos are the quality thread. Used together they address both problems.

    • Best for: moderate descent with acceptable skin thickness
    • Lasts: 12–18 months, repeatable
    • Local anaesthesia, 45–60 minutes, back at work in a day or two
    • From £950 depending on thread type and number

    3. Endolaser — energy where tightening happens

    Surface tightening devices are honest about what they do: they heat the top couple of millimetres of skin. That improves texture. It does not lift, because the limit is always how much energy the skin surface will tolerate before it burns. Endolaser removes that limit by going underneath — a fibre thinner than a hair is passed in the subdermal plane and delivers dual-wavelength energy (1470nm for water-rich tissue, 980nm for the fibrous septae) directly at depth. Far more energy, exactly where the contraction needs to occur. This is why you have never seen a superficial skin-tightening machine offered at Cosmedocs.

    • Best for: jowls with both a fatty pad and skin laxity; submental fullness
    • Reduces a measured volume of fat and contracts tissue in one pass
    • Tightening continues 3–6 months; a single session typically holds 18–24 months
    • £1,500, doctor-delivered under local anaesthesia

    On fat-dissolving injections — we stopped

    Clinic position. Cosmedocs no longer offers fat-dissolving injections for jowls or the submental area. Endolaser supersedes them, and once a full course of injections is costed the overall price is broadly similar.

    Injectable fat dissolving treats one thing: fat. In the lower face that is the smaller half of the problem. It does nothing for the skin envelope, so in anyone past their mid-thirties reducing the pad without tightening what covered it can read as deflation rather than definition. It also usually needs a course of two to four sessions with swelling after each, and the endpoint is harder to control.

    Endolaser does the fat reduction and the tightening in the same pass, under direct doctor control, with a defined endpoint. If we would not choose the injections for our own faces, we are not going to offer them to yours. Where the concern is genuinely body-contouring rather than the jawline, we use non-invasive body contouring instead.

    Sequencing matters: we support and reposition before we add volume, so the filler is placed under a jawline that is already sitting where it should.

    Are you a candidate?

    Well suited

    • · Early to moderate jowling
    • · Jowl improves when skin is lifted by hand
    • · Stable weight, non-smoker or willing to stop
    • · Wants a jawline that looks untreated

    Better served elsewhere

    • · Significant skin excess (lower face or neck lift)
    • · Heavy platysmal banding
    • · Active weight loss — treat once weight is stable
    • · Expecting a surgical result without surgery

    Comfort promise. We are deliberately sensitive to pain — fine needles, topical and local anaesthesia used liberally rather than sparingly, and you can ask us to pause or stop at any point. Threads and Endolaser are always performed under local anaesthesia.

    Frequently asked about jowls

    Jowls are the soft sagging that appears just in front of and below the jawline, where the clean edge of the jaw stops being a clean edge. They are caused by three things happening together: fat pads descending, ligaments and skin losing support, and bone resorption at the jaw and chin reducing the shelf that everything used to sit on. Fat is only one part of it, which is why fat-only treatments so often disappoint.

    There is no single best treatment — it depends on whether your jowl is mainly volume loss, mainly laxity, or both. Structural jawline and pre-jowl filler restores the bony shelf and blunts the shadow. Cog (barbed) PDO threads physically reposition descended tissue. Endolaser delivers laser energy under the skin to reduce a small volume of fat and contract tissue. At Cosmedocs most jowl plans combine two of the three.

    Filler does not remove a jowl; it rebuilds the structure the jowl is falling over. Placed deep on bone along the jaw angle, body and pre-jowl sulcus, it restores the shelf lost to bone resorption and makes the jawline read as a continuous line again. For early jowling in someone with reasonable skin quality this alone can be transformative. For heavier laxity, filler on its own adds weight without support.

    Yes, with the right thread. Mono threads are fine, smooth threads used in a mesh to improve skin quality and give gentle tightening — they do not lift. Cog threads carry small barbs that grip descended tissue and reposition it upwards, anchoring in the temporal or pre-auricular plane. Cogs are the lifting thread. Results last roughly 12 to 18 months and are repeatable.

    Surface devices heat the skin from the outside and are limited by what the skin surface can tolerate — the first couple of millimetres. That improves skin quality but does not lift. Endolaser passes an optical fibre thinner than a hair beneath the skin and delivers dual-wavelength energy (1470nm and 980nm) directly into the deep dermis, fat and fibrous septae. Far more energy, delivered where the tightening actually happens, without burning the surface.

    No. We stopped offering fat-dissolving injections. In the jowl and submental area they treat only fat, leave the skin envelope untouched and can leave a deflated result in anyone over about thirty-five. Endolaser reduces a measured volume of fat and tightens tissue in the same pass, is doctor-delivered under local anaesthesia, and once a full course of injections is costed the overall price is broadly similar. We would rather offer the treatment that supersedes it.

    At Cosmedocs, jawline and pre-jowl filler is £350 for 1ml and £650 for 2ml, with the Natural HD Jawline plan at £950. PDO thread lifting starts at £950 depending on thread type and number. Endolaser for the lower face and jawline is £1,500. The £50 consultation fee is redeemed against treatment on the day.

    Jawline filler lasts roughly 15 to 18 months in this area because there is little muscle movement. Cog threads last around 12 to 18 months. Endolaser continues tightening for three to six months after treatment and a single session typically holds for 18 to 24 months. Combination plans are usually reviewed at eighteen months.

    When there is significant skin excess, heavy platysmal banding, or the tissue no longer holds when lifted manually, a surgical lower face or neck lift gives a cleaner result and we will say so. Non-surgical treatment works best for early to moderate jowling. We would rather turn a treatment down than sell you a compromise.

    We are a deliberately pain-sensitive clinic. Filler is placed with fine needles and cannulas using products containing lidocaine. Threads and Endolaser are performed under local anaesthesia, which we use liberally rather than sparingly. You can ask us to pause or stop at any point.
