What the evidence says
Fat-dissolving injections are not equivalent to liposuction. Ingredient, product registration, approved area and injector technique must be verified; evidence and authorised uses vary by product and country.
Targeted fat-dissolving injection · Sisiface & Sisibody
A targeted injection that breaks down small, stubborn pockets of fat that resist diet and exercise — using Sisiface 10 ml for the face and double chin, and Sisibody 35 ml for larger body areas.

Quick answer
Mesofat is a broad clinic term rather than one standard medicine. Before considering an injection, the product, active ingredient, approved use and target anatomy should be identified; it is intended for selected localised fat concerns, not as treatment for obesity or general weight loss.
Mesofat (mesotherapy for fat) is a course of small injections that dissolve localised fat that won’t shift with diet or exercise. At Hori we use Sisiface 10 ml for delicate facial areas such as the chin and cheeks, and Sisibody 35 ml for larger areas of the body. It is a contouring treatment for specific pockets — not a weight-loss programme.
A fine needle delivers the solution directly into the targeted fat layer.
The active ingredients break down fat-cell membranes, releasing the stored fat.
The released fat is cleared by the body’s natural metabolism over the following weeks.
After a doctor assesses the area, the chosen solution — Sisiface 10 ml for the face or Sisibody 35 ml for the body — is injected through fine needles across a grid of points. A session usually takes 20–40 minutes; mild stinging or warmth is normal.
Temporary swelling, tenderness or bruising in the area is expected for a few days and is part of the fat-clearing process. Most people return to normal activities immediately. A short course of sessions is usually planned for the best result.
Results appear gradually as the body clears the released fat, typically over a few weeks per session, with several sessions spaced 2–4 weeks apart for a visible change. Because the fat is metabolised away, results are long-lasting when weight is kept stable.
Everyone responds differently. Before treatment, your doctor will examine the area and talk through a plan that makes sense for you.
No. Liposuction is surgery that removes fat physically; Mesofat is a non-surgical injection that dissolves small pockets gradually, with far less downtime but a more subtle, staged result.
Sisiface (10 ml) is formulated for delicate, smaller facial areas such as the chin; Sisibody (35 ml) is a larger volume for body areas. Your doctor selects the right one for the area treated.
It depends on the area and amount of fat. Many people need a short course spaced a few weeks apart; your doctor will advise a realistic plan at the assessment.
Usually little — some swelling, tenderness or bruising for a few days. Most people carry on with normal life right away.
