The jawline has a small published series: nine patients with jowl fat, treated once, about 90% rating the result good or very good, with the follow-up not stated. The fibre is passed under the skin along the jaw from small entry points, under local anaesthetic, in one session; its heat contracts the fibrous layer and can reduce the small fat pocket of a jowl. Every treatment is given by Dr Marie Duggan, GMC 7488383, at Endolift Clinic, 8 Devonshire Place, London, W1G 6HP, with the price in writing at a free consultation.
What the studies measured
- Jawline, 9 patients with jowl fat, follow-up not stated: about 90% rated the result good or very good after one session.
- The folds beside the mouth, 10 women, three months: the area of the folds from nose to mouth and the marionette lines down by about a third and their volume by about a quarter.
- The risk to know: temporary numbness from nerve irritation near the jaw has been reported and usually settles within two to four weeks, which is one reason the fibre's path along the jaw is planned with care.
What it does and does not do
Endolift tightens the skin along the jawline and can reduce a small jowl by contracting the fibrous layer, prompting new collagen and reducing the fat pocket where there is one. It does not lift heavy jowls the way a facelift does, and the doctor says so where surgery, or a thread lift that repositions tissue, is the better route. In our experience the people happiest with it are those with early softening of the jawline who want one session and a natural change.
The session and after
Endolift is given under local anaesthetic; in most of the published series the anaesthetic was injected along the path of the fibre. The fibre is passed under the skin from small entry points and moved in a fan and drawn back, pass by pass, and in our practice you go home the same day. Swelling, tenderness and some bruising, with redness at the entry points, settling over days; most people are back to normal in a day or two. The result develops over months and is photographed at the review in our practice. The risks page sets out the rarer effects.
Who it suits
In our practice, an adult with early to moderate softening of the jawline, a small jowl or a small fat pocket under the jaw, who wants one session rather than a course. A 2026 review lists metal implants, active infection, pregnancy, bleeding disorders, skin disease and cancer as reasons not to treat. The neck page and the eyes and cheeks page cover the areas beside it, and the full guide the rest.
