How it works
How do local fat-dissolving injections work?
Some injectable products disrupt the membranes of fat cells in the treated area. The local inflammatory response and the body’s clearance processes then act over time. The mechanism, evidence and approved area depend on the exact product, so one result cannot be assumed for every injection.
Precise mapping
The clinician identifies a small subcutaneous fat deposit and marks a treatment grid while avoiding vulnerable structures.
Local action
The selected product is injected at planned points and acts within the treated tissue rather than producing whole-body weight loss.
Gradual change
Swelling settles first; any contour change is assessed over the following weeks rather than immediately after treatment.

What happens before, during and after treatment?
A careful treatment pathway starts with diagnosis and informed consent, not the injection itself. The clinician confirms the product and area, maps the site, cleans the skin, administers the planned injections and provides written aftercare and a review plan.
- 1
Consultation
Review goals, medical history, medicines, allergies, previous procedures and whether an alternative would be more appropriate.
- 2
Examination and plan
Confirm that the concern is treatable subcutaneous fat, examine skin and anatomy, and explain the exact product and expected limits.
- 3
Preparation
Follow the clinician’s instructions about medicines and alcohol; arrive hydrated, having eaten normally unless told otherwise, and wear comfortable clothing.
- 4
Treatment
The area is marked and cleansed before small injections are placed according to the treatment plan.
- 5
Aftercare
Written instructions should cover swelling, pain relief, activity, heat exposure, massage, warning signs and who to contact.
