Submental fullness — the accumulation of fat under the chin — is one of the most common concerns we hear about, and one of the most resistant to diet and exercise. The fat cells in this area are stubborn, and for many people, they persist regardless of overall weight loss. Fat dissolving injections address this specific area directly.
What is this treatment?
We use deoxycholic acid — a bile-acid derivative that is FDA-recognized for the reduction of submental fullness. When injected, it disrupts the membrane of fat cells, causing them to release their contents and be gradually metabolized by the body over several weeks. The treated fat cells do not regenerate. Results are gradual and natural-looking.
How we approach it at Revitalize
A series of injection sessions is required — most patients need two to four sessions spaced four to eight weeks apart to achieve their desired result. Each session takes twenty to thirty minutes. The injection sites are mapped and marked before treatment. Common effects after treatment include significant swelling, firmness, bruising, numbness, and tenderness in the submental area — these are expected and typically resolve over one to two weeks.
Who is a good candidate
- ✓Adults with localized submental fullness (double chin) that is resistant to diet and exercise

- ✓Patients with good skin elasticity in the submental area
- ✓Those willing to complete a series of sessions and manage the expected recovery
Not appropriate for
- ×Pregnancy or breastfeeding
- ×Active infection in the treatment area
- ×Prior surgery in the submental area — requires evaluation
- ×Those expecting dramatic weight loss from this treatment — it targets localized fat, not overall weight
- ×Poor skin laxity — loose skin in the area may require a different approach
What to expect at your appointment
Consultation: We evaluate the submental area, assess skin laxity, and determine the number of sessions likely needed.
Treatment day: Injection sites are marked. Treatment takes twenty to thirty minutes.
Post-treatment: Significant swelling, firmness, and possible bruising under the chin are expected and normal. This typically peaks at two to three days and resolves over one to two weeks.
Between sessions: Sessions are spaced four to eight weeks apart to allow full resolution before the next treatment.
Results: Gradual reduction in submental fullness develops over the weeks following each session as treated fat cells are metabolized. Final results from the series emerge over two to three months.
