The area under the chin is where the Genius face studies measured their main result: less volume under the chin after one to three sessions, in a 2025 study of 30 patients and a 2026 study of 53. Fine needles place radiofrequency heat deep under the chin, so the skin tightens and the fullness under the chin reduces as the collagen rebuilds over about six months. Three sessions four to six weeks apart, at Lutronic Genius RF London, 8 Devonshire Place, with the price in writing at a free consultation.
What it does under the chin
A soft double chin that is loose skin with a little fullness is what the heat changes. A large fat pad is a fat-reduction question, and the clinician says at the free consultation whether fat freezing or another treatment at our sister clinics comes first, with Genius afterwards for the skin. The line from the chin to the neck sharpens as the tissue contracts.
The evidence
The 2025 study of 30 patients found the change in volume under the chin rising with the total energy delivered. The 2026 study of 53 patients, in two groups with average ages of 51 and 56, reduced the volume under the chin alone and with a laser, with no serious side effect. The lower face page sets them out, and the results page how long it holds.
The session and who it suits
Numbing cream for 30 to 45 minutes, the tip stamped under the chin at depth, 15 to 20 minutes in our practice. Redness and swelling for one to three days, light crusting for up to five days in our experience, sunscreen daily. Adults with a soft double chin that is mostly skin, on most skin types after assessment, with darker skin treated at lower energy after a patch test in our practice.
