What Is It?
Fat-dissolving injections for the double chin use phosphatidylcholine (PCDC) or deoxycholic acid to non-surgically reduce submental fat. The injectable solution breaks down fat cell membranes so that the body can clear the released fat through its lymphatic system over several weeks.
How It Works
The fat-dissolving solution is injected in a grid pattern into the submental fat pad under the chin. The compound disrupts fat cell integrity and triggers a controlled inflammatory response that leads to fat cell death. The body processes and removes the cellular debris over 4–8 weeks per session.
Realistic Results
Gradual reduction in double chin fullness over 4–8 weeks after each session. Most patients need 2–4 sessions. The improvement is permanent as fat cells once destroyed do not return, though weight gain can increase the remaining fat cells.
Recovery
Expect 1–2 weeks of visible swelling and firmness under the chin after each session. The area often feels hot and tender for the first few days. Social downtime of 3–5 days is typical per treatment.
Risks & Complications
- !Significant swelling expected for 7–14 days
- !Nerve injury affecting the marginal mandibular nerve (risk of asymmetric smile)
- !Skin dimpling or irregularity
- !Incomplete correction
- !Infection at injection sites
