Jawline · SMAS Depth · Pacific Plaza
HIFU treatment for jowls heats the SMAS and skin along the lower cheek and jawline so the layers that let the jowl slide become firmer. It suits early to moderate jowling in a face with good volume. It cannot lift a heavy jowl that moves freely, take away the fat inside it or refill a flat midface.
A jowl forms where tissue from the lower cheek slides down and stops against the mandibular ligament, the anchor just behind the dip in front of the jowl. Loose SMAS and ligaments, thinner skin and lost midface volume feed it; jowls and lower face sagging explains the anatomy.
Focused ultrasound heats small points in the SMAS and skin over the jowl, which remodel over 8–12 weeks. The layers firm up, but HIFU does not carry tissue back up, remove fat inside the jowl or restore volume above it. In an early jowl that can be enough to sharpen the jawline; in a heavy one it is not.
At A Glance
Dr Sin Yong, Global Key Opinion Leader in Facelifts & Body Contouring, palpates each zone first. The 4.5 mm depth goes into the SMAS of the lower cheek and jawline where tissue allows, then a 3.0 mm pass; thinner skin at the front of the jaw gets 1.5 mm. Lines follow the direction the tissue slid, avoid the nerve near the jaw edge, and keep 4.5 mm off thin tissue on bone.
Who It Suits
HIFU suits early to moderate jowling with good volume and reasonable skin: the cheeks are not hollow, and the jowl does not swing when you turn your head.
| What drives the jowl | Sign at examination | Where it is treated |
|---|---|---|
| Lax SMAS and skin | Firm jowl that does not swing; full cheeks | HIFU, or the VF Lift – Vertical Facelift |
| Fat inside the jowl | Fullness that stays when you lie down | Time Freeze Laser LCLR |
| Flat midface | Hollow cheeks above the jowl | Cheek support first |
| Heavy, mobile jowl | Swings on turning; loose skin | Thread lift or surgical opinion |
| Platysma pull | Bands at the front of the jaw on clenching | BTX, not heat |
The Decision
Jowls are rarely one-layer problems, so HIFU is often one step of several.
A heavy lower face with much loose skin is a surgical question, and Dr SY will say so.
On The Day
Afterwards
Jawbone tenderness, slight swelling and sometimes a small bruise settle over days; see HIFU downtime and HIFU aftercare. Early firmness is swelling; the result is judged at about three months.
Safety
Careful placement lowers these risks without removing them. Contact the clinic the same day about a welt that does not flatten, marked or one-sided swelling, numbness that persists, or any change in mouth movement; see HIFU complications.
