Face fat-dissolving injection
Targets cheek and submental fat

In short
A fat-dissolving solution is injected into the subcutaneous fat of the cheeks, jawline or under the chin to reduce pockets that diet and exercise rarely reach. It is normally done as a course of three to five sessions two to four weeks apart, with visible change from the second session.
- Session time
- About 15 minutes per session
- Downtime
- Swelling and tenderness for 2–4 days
- Result & repeat
- 3–5 sessions, 2–4 weeks apart
How it works
The solution breaks down fat-cell membranes; the body then clears the released fat through the lymphatic system and liver. Because that takes weeks, the change appears gradually rather than instantly.
What the clinic highlights
- Spot-reduces fat on a jawline that stays heavy even at a normal body weight.
- Delivered as a course, with the dose adjusted each visit to the response.
- Often combined with a lifting laser so the skin does not slacken as fat reduces.

Who it suits
- Stubborn submental or cheek fat
- Want a sharper jawline without liposuction
- Comfortable with a gradual, course-based result
Aftercare
- Drink more water and avoid very salty food to limit swelling.
- No firm massage on the area until tenderness resolves.
FAQ
Can the fat come back?
Destroyed fat cells do not return, but the remaining cells can still enlarge if your weight rises significantly.
Is one session enough?
Usually not — each session removes a limited amount for safety, so a course is standard.
