What is a Fat Loss Injections?

Injectable Fat Removal

What are Fat Loss Injections?

Fat loss injections, also called fat dissolving or lipolytic injections, work by using a formula of compounds — often deoxycholic acid, which is naturally produced in our bodies to help absorb fat — to destroy the body’s fat cells in a specific area. Once dissolved, your body will absorb and remove these fat cells naturally over the course of a few weeks. It’s great for smaller, targeted areas like under the chin, thighs, upper arms and lower abdomen.

The Advantages of Fat Loss Injections

  • Targets small areas of stubborn fat
  • Improves definition of the jawline, chin, arms, even the belly
  • Non invasive and in-clinic treatments fast in nature
  • Small amount of downtime with long lasting results
  • Improves self-esteem by encouraging visible progress

Classification: Non-invasive.

Downtime: 24-48 hours of mild swelling or tenderness.

Best for: Patients who want a more sculpted jawline or who have less volume under the chin

Best for: Healthy adults with stubborn midsection fat who hope for streamlined silhouette.

The procedure
Precise Fat Targeting
How do fat loss injections work?

A specially formulated solution, typically deoxycholic acid, is injected into specific fat pockets, where it disrupts fat cells and the body metabolizes them out over time. It’s a soft, accurate approach that’s most effective for small, stubborn spots.

Mild Injection Discomfort
Will it hurt?

During the injection, you may feel a light stinging or warmth, but most people find it mild. You might have some post-procedure pain swelling or soreness that could be alleviated by cold packs or OTC pain medicine.

Quick Injections Session
How long does it take?

It takes approximately 20–30 minutes per session. It’s an in-and-out appointment you can walk in on your lunch break and get right back to your day.

Suitable Candidates Only
What age is ideal?

Fat dissolving injections are for adult use only (over 18s) and to be used by those in good general good health. There’s no maximum age, so long as your skin is in decent condition and your expectations realistic.

Boost Your Results
Can I combine it with other treatments?

Yes. Most clients also choose to match their fat loss injections with other treatments such as skin tightening, microneedling, and facial contouring.

Post-Treatment Wear
Can I wear tight clothing after?

It’s a good idea to refrain from wearing tight or constricting clothing over the treatment site for at least 48 hours. Continue to wear soft, breathable fabrics that will give the area a chance to naturally settle.

Session Frequency Guide
When can I have another treatment?

The majority of clients will require 2-3 treatments spaced one month apart to achieve their best results. As you progress, your practitioner will recommend accordingly.

Sustain Your Results
How to maintain results?

a healthy lifestyle. Stay active, eat good food and avoid significant weight fluctuations to maintain your results for the long term.

Safe Treatment Pairing
Can I do other treatments at the same time?

Yes—but spacing is key. If you’re going to do this, plus other non-invasive treatments like laser or body sculpting, check with your doctor for a protocol that won’t overwhelm your skin.

The essentials

  • Know Your Reasons and Expectations: Fat dissolving injections are best suited for very particular areas—not overall weight loss. You’ll naturally want to align your goals with what’s actually possible.
  • Avoid Blood Thinners and Smoking: You be asked to not take aspirin, ibuprofen, fish oil, alcohol for 24–48 hours prior to treatment unless otherwise instructed by your doctor. These may enhance the risk of bruising and swelling following the procedure.
  • Keep the Area Clean and Dry Pre-Op: Drink lots of water before your session and come in with clean skin, no moisturisers, makeup, or oils on the treatment site. This reduces irritation and helps ensure the injections work evenly.
  • Dress for Comfort: Loose clothes: If you’re having the belly, arms or thighs treated, wear loose-fitting clothes on the day. Steer clear of anything tight that could rub up against the area post-treatment.
  • Consult Your Surgeon Thoroughly: Mention your medications, previous aesthetic procedures, allergies and health issues to your provider. This isn’t a one-size-fits-all regimen, so transparency can prevent potential hazards and make sure you get the best job.

  • Post-Treatment Swelling and Redness: Mild swelling, firmness or redness at the injection site for several days is entirely normal. Some patients also experience warmth, puffiness, or mild tenderness, particularly under the chin or across the midsection. Most of these reactions resolve in 48-72 hours.
  • Avoid Touching the Treated Area: Do not press, poke or attempt to massage the work area even if it looks or feels swollen. Leave the solution alone so you can develop with fine and natural results. Opt for loose, comfortable, soft fabrics that won’t irritate or rub against the treated area.
  • Skip Harsh Products and Heat: Avoid using scented lotions or oils and active skin care products in the area, particularly after facial injections. Steer clear of saunas and steam rooms, hot showers and anything that raises heat or inflammation for 48 hours.
  • No Intense Activity Until Settled: Avoid any exercise or activity that may induce sweating or pressure in the treated area for 2-3 days. Regardless of if it is cycling, heavy lifting, or core exercises—let your body at least get to the point that it can actually begin to process the breakdown of fat in a healthy way.
  • Attend Your Follow-Up: If your provider suggests doing so, go back for a follow-up, so that you can monitor your progress together and decide whether you need more sessions. Fat loss injections often need more than one round to make a real impact, and reviews can fine-tune the treatment to your body’s response.

  • Let Healing Happen Gradually: You might even notice some differences in as little as the early weeks, but the final results in most cases may not appear for at least a year. It takes weeks for the body to naturally flush the broken-down fat. Swelling typically recedes in days, but the internal remodeling continues for much longer
  • Avoid Friction and Pressure: Just because the surface appears calm doesn’t mean everything has settled. Do not wear constrictive clothing, tight waistbands, helmets, or anything that places repetitive pressure over the treated area.
  • Hold Off on Intense Treatments or Massages: Stay away from other cosmetic treatments, massages or lymphatic tools in the region, unless directed otherwise by your provider. These could interfere with the taking out of fat and potentially irritate the skin while it settles below the surface.
  • Avoid Using Products Unless Recommended: Do not use depilatory creams, scrubs, or active ingredients including retinol or acids on the treated area. Unless your provider recommends a product, keep it simple: clean skin, gentle care, no extras.
  • Stick to Your Check-Ups: Even if you are feeling great, stay on schedule with reviews. Your technician evaluates how your body is responding, whether more sessions are necessary, and that your results are progressing evenly and safely.

Why Choose Fat Loss Injections?
Subtle Shape Refinement
Subtle shift that makes a big difference

Some body concerns don’t need a radical solution. Perhaps it’s just one or two areas that feel a bit out of whack — a new fullness under the chin, a bit of softness along the waist, a tiny bulge in a hot spot that tightens clothing a bit more than feels appropriate. Fat dissolving injections are a non-invasive way to eliminate those problematic areas without surgery, recovery, or trial and error. It is a pragmatic and effective treatment for anyone who feels out of touch with their own shape.

Target Issues
Confident, Defined, Contoured
  • Stubborn pockets that don’t respond to effort

    You eat well. You move your body. But that tiny bulge will not budge. This treatment is meant for those very areas ones that won’t budge even when you’re doing everything right.

  • Feeling limited in terms of what fits on his body

    It’s not about the size — it’s about how things fit. Whether it’s a tight waistband, a bra gap or a turtleneck that grabs the wrong curve, these fat loss injections can help you clothes drape better, naturally.

  • Wanting to feel more balanced overall

    If one area is a little bit “off,” it can throw off how you feel about your entire appearance. These injections improve but don’t remake achieving a better balance with your natural frame.

Empowered Subtle Change
Smoother lines, Sharper edges

This isn’t a quest for perfection or for fitting into some impossible ideal. It’s about making small changes that allow you to feel more like yourself. Whether it’s finally revealing your sharp jawline again, or sculpting your silhouette into a streamlined side profile, fat loss injections allow you to target small areas of concern in a safe, gradual way without taking it too far.

Recovery timeline
1 – 2 Days

You might experience no more than a fraction of swelling, tightness or minor tenderness at its best result. Some patients also experience firmness or a sense of being “full” at the injection site.

  • Do not wear tight clothes, apply heat directly, or scratch the area. Keep your skin clean and moisturized.
  • Rest is recommended, though you can go back to easy movement as long as the area doesn’t get irritated.
6 – 7 Days

Swelling is expected to subside, and you’ll notice any mild bruising fade, too.

  • The area may still be slightly firm to the touch, but many symptoms will have subsided.
  • Your clinic provider might recommend a brief check-in to see how your body is holding up and whether you need another session down the line.
1 – 2 Weeks

The majority of tenderness is gone, and the area begins to feel slightly more calm. All firmness or puffiness is visibly decreased.

1 Month

Some contour change is visible with the lines in the treated area being smoother and more even.

  • The skin may not be completely settled yet, but you might find you have more definition in places such as the chin, stomach or arms.
  • Opt, instead, for loose-fitting and breathable clothes, and steer clear of anything that will chafe or cause a lot of friction.
3 – 6 Months

This is the time full results are most noticeable. The body has purged the liquefied fat, and the region has molded into a slimmer, more defined form.

  • If you had follow-up treatments scheduled, your provider will evaluate whether they are still necessary.
  • The majority of clients are pleased with results at this stage and do not require any further sessions.
The benefits

  • More Defined Contours in Targeted Areas: Fat dissolving injections offer subtle reshaping in the chin, lower belly, upper arms or flanks but without surgery. When done right, they just enhance your natural lines without it looking like it was done.
  • Improved Comfort During Daily Activities: Excess fat in small places can cause a lot of discomfort — whether it’s a lump under the bra strap, chafing thighs, or tightness under the chin. Post-treatment, many patients report feeling lighter and more mobile, with less friction in those problem areas.
  • Easier Fit in Clothing: Even a slight reduction in fat volume can dramatically change how clothes fall on your body. Once the injections kick in, many people find that necklines, waistbands and sleeves look smoother, more flattering without a squeeze or slide.
  • Visible Results Without Going Under the Knife: Because the treatment works gradually, you avoid the “sudden change” look. Most patients say they look like themselves—just a bit more sculpted and refined. It’s a discreet way to get results, especially in professional or social settings.
  • Speedy Recovery with Little Down Time: The process is brief under an hour and requires no time off work or prolonged healing. Most clients are back to their normal activities within a day or two, other than some mild swelling or tightness.

  • Natural-Looking Outcome: The aim isn’t to change dramatically — but to enhance subtly. The majority of patients say that the area appears more harmonious, without looking as if anything was done.
  • Relief from Clothing Discomfort: Things that looked good in a tight jean or bra could press on soft bulges to the point of discomfort or self-consciousness. After the area is flushed away, most patients feel more comfortable in their clothing and more confident in their natural shape.
  • Confidence That Comes From Subtle Changes: This is not about impressing anyone else; it’s about feeling more comfortable in your own body. For others, finessing one difficult area can be the ticket to feeling in control and quietly confident once again, without having to say a thing to anyone.
  • Long-Lasting Improvemen: Once fat cells have been dissolved and swept out, they do not grow back. Provided there is no weight gain, results can last for the long-run with no additional maintenance or top-up sessions in the same area.

  • Small Procedure, Big Impact: No general anaesthetic, no recovery room, no time off. Well, just gradual results that fit into your life without major inconveniences.
  • Comfort Where It Matters Most: A lot of patients feel less self-conscious and are more comfortable going to social events, meetings, getting their photos taken. The treatment often gets rid of that one thing that they clung to, and replaces it with ease.
  • Tailored to Your Needs: You can’t assume this is a one-size-fits-all solution. Your individualised treatment plan is centred on your natural shape, personal goals and lifestyle—so you can work out how much reduction is right for you and your needs.

Am I suitable?
Are Fat Loss Injections right for me?
  • You may also be a suitable candidate if you have small, localized deposits of fat that are difficult to get rid of with diet and exercise. These are best for people who want some mild contouring, not substantial fat loss. Typical treatment areas are under the chin, around the lower abdomen, sides, inner or outer thighs, arms and back.
  • Good candidates are generally healthy, at or near their desired weight, and have realistic expectations.
The Risk
What are the usual and potential side effects of fat loss injections?

There are risks associated with fat dissolving injections as with all cosmetic treatments. Side effects are mostly temporary and mild, but there can be complications such as:

Usual Side Effects

  • Swelling: Local puffiness may occur, but normally settles after a few days.
  • Bruising: Tiny bruises at the injection sites may develop and typically disappear within 1 week.
  • Softness or Hardness: Some clients will experience bruising or a thickened texture as the fat is dissolved: this is normal and is going to pass.
  • Heat or Redness: Mild warmth and redness can appear for a day or two.

Adverse Effects

Although rare, the following complications may occur:

  • Infection: Very occasional, but a risk if post-treatment hygiene is not strict and careful.
  • Lumps or Bumps: The fat cells may at times be destroyed more in some areas than in others and subsequent treatment may be needed at these specific sites.
  • Nerve Irritation: In rare situations, in the facial region or chin, it can experience temporary numbness or be sensitive.
  • Overcorrection or Uneven Results: Treat too much and you could end up looking sunken or lopsided, especially if treatments are rushed or pushed too close together.

All of these risks are significantly reduced when you have your treatment administered by a suitably qualified, experienced aesthetic practitioner who has a strong understanding of face and body anatomy and follows up with tailored aftercare support.
