✨ Permanently dissolve stubborn fat around your waist and tummy — no surgery, no gym hours wasted.
✅ How it works:
A prescription bile acid is injected into the fat layer beneath your skin, breaking down the walls of fat cells so they release their contents. Your body naturally clears the released fat through your lymphatic system over the following weeks. Once destroyed, those fat cells are gone for good.
✅ Who it's for:
Anyone with a stubborn ring of fat around the middle that won't shift with diet or exercise
People near their ideal weight who want to contour their waist from every angle
Those who can plan around a week of visible swelling
✅ The benefits:
Permanent reduction of treated fat cells — they don't grow back
Contours your waist from front to sides for a smoother silhouette
No general anaesthetic, no scars, no time off work needed
Results improve for weeks after each session as your body clears the fat
Targeted treatment that respects your natural shape
✅ What's included:
Full consultation and pinch test to check your fat layer thickness
Cleansing and marking of the treatment area
Multiple small injections across abdomen and flanks using fine needle or microcannula
Product contains built-in numbing for comfort
Aftercare guidance and follow-up support
✅ What to expect:
A course of 2 to 6 sessions, spaced 3 to 4 weeks apart
First visible change around 3 to 4 weeks after treatment
Best results seen 4 to 6 weeks after your final session
Results last permanently if you maintain stable weight
💡 The swelling you see is proof it's working — your immune system flooding the area to clear the destroyed cells.
Common questions
Is there any downtime?
You'll have noticeable swelling, redness and firmness for 3 to 7 days, with the area feeling tender and possibly lumpy underneath. Most people carry on with normal activities but plan looser clothing and avoid anything that needs a tight waistband during this time.
Does it hurt?
It's not painless but it's manageable — the product contains numbing, and we can apply topical anaesthetic beforehand. Most people describe a warm stinging sensation during the injections that settles quickly afterwards.
How many sessions will I need?
Most people need a course of 2 to 6 sessions, spaced 3 to 4 weeks apart. If you've got a wedding, holiday or big event coming up, it's worth starting at least 12 weeks beforehand so everything has time to settle and look its best.
How long do the results last?
You'll usually start seeing a difference around 3 to 4 weeks after each session, with the best results showing 4 to 6 weeks after your final treatment. Once those fat cells are destroyed they don't come back — the result is permanent as long as you keep your weight stable.
Are there any side effects?
You can expect significant swelling, redness, warmth and tenderness in the treated area for 3 to 7 days, with some bruising and firm lumps under the skin that soften over 2 to 3 weeks. Less commonly you might notice temporary numbness or itching. Serious complications are rare but include infection, nerve damage or skin irregularities.
Before your treatment
Drink plenty of water for 48 hours before — hydration helps your lymphatic system
Avoid alcohol for 48 hours — it thins blood and increases bruising
Stop anti-inflammatory medications 1 week before unless prescribed — check with your doctor
Eat normally on the day — don't come hungry or overfull
Wear loose, comfortable clothing that won't press on your waist after treatment
Aftercare
Expect significant swelling for 3 to 7 days — this is normal and shows it's working
Drink 2 to 3 litres of water daily for 1 week to support clearance
Avoid alcohol for 48 hours — it slows healing and increases bruising
No gym, hot baths, saunas or swimming for 48 hours
Tenderness and firm lumps under the skin can last up to 2 weeks — these soften as results appear
Who it isn’t suitable for
Do not book if you are pregnant or breastfeeding
Active infection or inflammation at the treatment site
Bleeding disorders or taking blood-thinning medication
Diabetes, liver or kidney disease
Autoimmune conditions
Known allergy to deoxycholic acid or any product ingredients
Previous surgery or significant scarring in the area that may affect lymphatic drainage
Lipodystrophy disorders
