Quick answer
Fat dissolving injections break down small pockets of stubborn fat, which the body then clears over several weeks. Most people need two to four sessions, four to six weeks apart. At Serra Aesthetics in Walthamstow, sessions cost £80 (small area), £110 (medium) or £140 (large). It isn't a weight-loss treatment.
What are fat dissolving injections?
Fat dissolving injections — sometimes called injection lipolysis — use a solution that breaks down the outer layer of fat cells in a targeted area. Once those cells are broken down, your body’s natural processes clear them away over the following weeks.
The key thing to understand is what they’re for: small, pinchable pockets of fat that don’t shift with diet and exercise. They’re not a weight-loss treatment and they won’t tighten loose skin.
Which areas can be treated?
- Under the chin (“double chin”)
- Upper arms
- Bra line and back
- Flanks (“love handles”)
- Lower tummy
- Inner thighs
At your consultation, Berna will look at the area and confirm whether it counts as small, medium or large — which sets the price and how much product is used.
How many sessions will I need?
Most people need two to four sessions, spaced four to six weeks apart. That gap gives your body time to clear the treated fat and lets us see the real progress before deciding on the next step. Smaller areas, like under the chin, often need fewer sessions than the tummy.
What the first week feels like
Being prepared makes it much easier:
- During treatment: a sting with each injection, then a warm or tingling feeling.
- Days 1–3: swelling and tenderness are at their most noticeable. Under-the-chin treatments can look quite puffy — plan around important events.
- Days 4–7: swelling settles. The area may still feel firm or slightly numb, and any bruising fades.
Avoid hard exercise, saunas and hot baths for 24–48 hours, drink plenty of water and keep moving with gentle walks.

Is fat dissolving right for you?
It’s likely to suit you if:

- you have a specific area that hasn’t responded to diet and exercise;
- you’re happy with gradual results over a few months.
It isn’t suitable during pregnancy or breastfeeding, or with certain medical conditions. Have a look at our fat dissolving treatment page for prices and aftercare, or book a free consultation in Walthamstow to talk it through.
