Fat-dissolving injections in Montreal: the complete guide (areas, sessions, results)
Written by Douae Elle · October 13, 2026

You eat well, you move, but a small pocket of fat refuses to budge, under the chin or elsewhere? Fat-dissolving injections (lipolysis) are designed for exactly that: targeting a small volume of localized fat, without surgery. Here's the complete guide to know if it's right for you.
How it works
The injected product destroys fat cells in the targeted area. The body then gradually clears those cells over the following weeks. Destroyed cells don't grow back, but the remaining cells can still grow if weight increases: a stable lifestyle helps keep the result.
The product, technique and dose are chosen for the area and your anatomy, after an assessment.
Areas treated
- Double chin: the most requested area.
- Jowls and jawline: for a sharper contour.
- Small localized pockets on the body, depending on the assessment.
For larger body areas (abdomen, flanks, thighs), other treatments are often better suited, such as EvolveX.
What lipolysis isn't
- It isn't a weight-loss method. It's for small pockets, in people close to their healthy weight.
- It isn't a treatment for loose skin. If the skin is lax, we'd rather talk about radiofrequency microneedling (Morpheus8).
- It isn't instant. The result builds over weeks.
How a session goes
1. Assessment: we examine the area, check the pinchable fat and review your history.
2. Marking: the area is mapped precisely.
3. Injections: small targeted injections, in about thirty minutes.
4. After: ice and clear instructions.

The following days
Swelling, tenderness, sometimes bruising or a feeling of warmth are normal for a few days. Under the chin, swelling can be more noticeable in the first days: schedule your session well away from an important event.
How many sessions?
Most people need a series of sessions spaced several weeks apart. The number depends on the amount of fat and how your body responds. Your plan is set at the assessment.
When do you see results?
Results develop gradually over the weeks after each session, as the body clears the destroyed cells. We assess the result after each session before planning the next. Results vary from person to person.
Who isn't eligible?
Treatment isn't recommended during pregnancy and breastfeeding, with an infection in the area, certain medical conditions or certain medications. We check all of this with you at consultation.
A complete plan for the lower face
Lipolysis is often combined with other treatments:
- Masseter neuromodulators (Botox / Dysport) when width comes from the muscle. See how long they last.
- Jawline filler for definition.
- Radiofrequency microneedling (Morpheus8) for skin firmness.

FAQ
Do fat-dissolving injections hurt?
You feel a burning or tingling sensation for a few minutes. Ice helps after the session.
Are the results permanent?
Destroyed cells don't come back, but the remaining cells can grow if weight increases.
How long does swelling last?
Usually a few days. It can be more noticeable under the chin.
Does it replace liposuction?
No. Lipolysis is for small localized pockets; it doesn't remove large volumes of fat.
