Are Fat Injections Safe?

Posted on May 26, 2022

A fat injection treatment is an excellent alternative to plastic surgery.

Fat injections are a popular way to look more youthful. With this popularity, many people ask if this non surgical procedure is safe.

If you’ve been asking the same question, you’re at the right place.

In this article, I will talk about fat injections, the cost, and how to prepare for them. I will also talk about how they last and how these cosmetic procedures usually go.

What Is Fat Grafting or Fat Injections? 

Fat transfer, also known as fat grafting or fat injections, is a natural, minimally invasive therapy for people who want to go under fat removal and replace age-related volume loss in their face while also softly smoothing out wrinkles. Fat removal is done from areas of the body where there are a significant quantity of it, such as the thighs, belly, and/or buttocks.

The fat is then spun or filtered to separate healthy fat cells from damaged fat cells before being injected into the face or hands.

Ageing has an impact on everyone’s skin, and unfortunately, as nature’s way of signalling that we are getting older, skin all over your body can lose volume. It also becomes loose and relaxed. Natural alternatives to synthetic fillers and implant treatments have been made possible by medical and scientific advances.

A fat injection procedure cost depends on many factors.

Fat Transfer to Face Cost

If you want to transfer fat to more than one place, the cost will undoubtedly rise. In general, you should budget at least £3,000 for this treatment. Since the outcomes are permanent, the fat transfer costs less than other operations.

The total cost will be greatly dependent on your unique circumstances and the number of sessions required to attain your desired objectives. If you have any more queries, please do not hesitate to call the clinic. We are here to assist you!

Fat Grafting Face Cost

At our practice, most face fat transfers cost between £3,000 to £6,000 on average. However, this price might vary based on each patient’s unique needs and expectations.

A fat injection treatment can reduce signs of ageing, just like plastic surgery.

Fat Injections in Cheeks

Do you have volume loss in your cheeks and face as a result of ageing?

At my Harley Street London Clinic, we provide facial fat grafting to help enhance the appearance of your face. Fat grafting on Harley Street London provides natural, long-lasting results for clients looking to restore lost volume and minimise the appearance of fine lines and wrinkles.

A fat transfer to face technique rejuvenates the face by injecting fat into areas such as the cheeks or lips. I, Dr. Julian De Silva, a board-certified plastic surgeon, take excess fat from your body. Then, I use it to improve the volume of your face and correct sunken cheeks.

How to Prepare for Fat Grafting

Because liposuction procedures are used, fat injection is a more complicated operation than the usage of other cosmetic dermal fillers. These methods are used to remove the fat before injection.

While fat injection at Harley Street is a non surgical treatment that is normally performed under local anaesthesia, it may be necessary to use a local anaesthetic with sedation if bigger volumes of fat are being obtained by liposuction procedures.

Preparing for your fat injection at my Harley Street London Clinic may entail the following:

  • A medical examination or laboratory tests.
  • Taking new meds or making changes to your present medications.
  • Smoking should be avoided for at least a month before surgery.
  • Aspirin, anti-inflammatory medications, and herbal supplements should be avoided due to the increased risk of bleeding.

How Is Fat Grafting Done?

Fat is extracted from one region of your body, cleansed and purified, and then carefully reinjected into the parts that require augmentation with specially developed needles. To obtain the desired outcome, the fat grafting technique may need to be repeated numerous times. Fat grafting at Harley Street is a three-step method that includes (1) harvesting, (2) purification and transfer, and (3) placement.


You and I will decide on a fat removal spot and inject it with a topical anaesthetic. I will next make a small incision in the area to be treated for fat removal. Using a sterile approach, insert a cannula attached to a syringe to delicately collect fat (liposuction).

Purification and Transfer

Once enough fat has been extracted from the donor region, your surgeon will process it to prepare the fat cells for transfer to tiny needles for fat injection. Prior to injection, purification may necessitate the use of a centrifuge to spin the fat or a filtration procedure to eliminate contaminants.


The location where the graft will be placed will next be prepped. A needle or cannula will be inserted into the incision location of the augmented site by your surgeon.

Typically, the injection needle is passed in and out of the locations to be increased several times. With each withdrawal of the needle or cannula, a line of fatty tissue packages is meticulously laid in natural tissue planes.

This procedure is continued until the necessary correction is obtained, resulting in a grid of grafted fat. Some surgeons advise rubbing the transplanted regions to achieve a pleasing shape. Others prefer to use the placement approach to produce the desired shape. A dressing or bandage may also be applied to the grafted region by the surgeon.

I and the entire staff will help you achieve the most attractive and natural-looking outcomes possible. At the same time, we’ll also make your surgery experience at Harley Street London as easy and comfortable as possible.

Are You a Good Candidate for Body Fat Transfer? 

Fat grafting is used to increase or fill in volume-deficient regions. Hands, face, and lip depressions in the skin (after liposuction and scarring), and the breast and buttocks are among the most commonly grafted or injected locations for augmentation.

Of course, donor locations from which fat may be extracted are required. It is critical that you do not have any circulation issues, whether from a medical condition or from smoking.

If you have facial wrinkles such as laugh lines, smile lines, or crow’s feet, fat from your belly, thighs, or other places can be extracted and injected into your face.

Acne scars and depressed parts of the face, lips, and cheeks can be filled in as well. Grafted fat can also be used by your plastic surgeon to reduce lines between your nose and lips, remove skin depressions or indentations, and reduce forehead wrinkles. Hence, fat grafting is a great non-surgical wrinkle treatment.

Recovery for fat grafting is minimal and usually does not last long.

Do Fat Injections Really Work?

Yes, fat grafting or transfer is effective.

Millions of people have had these injections. There have been no serious adverse effects documented with therapy, although you may feel redness or minor bruising at the injection site, as well as swelling that may linger for a few weeks.

As a consequence, you will not receive your full findings until the suggested course of therapy has been completed. The downtime is limited, and you may resume normal activities; however, you may wish to take a day off from work and exercise.

The operation does not require general anaesthetic, although we do utilise local anaesthetic to reduce discomfort. We encourage that you come in for a follow-up visit a few weeks following the treatment so that we can assess your progress.

How Long Does Fat Transfer Last?

The effects of these injections can persist for years, and in many cases, they are permanent.

Once the fat has been absorbed by your face tissues, it will stay there for a long time. A second treatment can be performed to sustain the benefits, although this is uncommon. If you intend on having additional treatments such as lip fillers, cheek fillers, and chin and jawline enhancement, the duration of the results should not be affected.

Many factors affect the longevity of fat grafting.

Factors that Can Affect the Longevity of Fat Grafting Results

Several factors can affect the longevity and results of this treatment. A few examples include:

The Technique Used for Harvesting Fat

One of the most crucial aspects in deciding how long a patient’s effects will endure is the procedure employed to extract fat. The strip method and the tumescent technique are the two basic methods for collecting fat tissue from the body. The tumescent procedure involves injecting a saline solution into fat tissue, causing it to disintegrate and be absorbed by your body. This guarantees that the harvested region is not only clean, but also free of nerve endings, blood vessels, and other potentially damaging elements.

How Fat Is Injected

The fat should be injected gently with micro-cannulas so that it is equally absorbed by your body. This reduces the likelihood of fat re-accumulating in regions where you don’t want it, such as beneath your chin, on the sides of your nose, or between your eyes.

The Recipient Area

The fat is injected into many layers of the skin, with some remaining in the outer layer and others dissolving and being reabsorbed by the body. If you have a lot of excess tissue or are really deep, we may need to inject at various depths over time to smooth things out.

How Well Your Body Adjusts to the Transferred Fat

The implanted face tissues require new blood and nutrients from your body. To remain permanently, the transplanted fat cells must merge with the existing tissue. If any of the injected fat does not nourish, you may need to return for touch-up procedures. If you are skinny or of medium weight at the time of injection, your body adjusts rapidly.

However, individuals with a lot of excess weight may take longer. This is because their skin has expanded over time and is no longer as elastic.

Are There Injections To Dissolve Fat?

Injection lipolysis, also known as intralipotherapy, is a minimally invasive medical method for reducing fat in specific areas. Intralipotherapy, often known as fat dissolving injections, is a kind of mesotherapy and one of the nonsurgical fat reduction alternatives.

Fat dissolving injections, also known as Aqualyx, are a safe and effective therapy that lowers the number of fat cells in the treated region. Plus, fat dissolving injections deliver long-lasting benefits, allowing you to get rid of those frustratingly wobbling areas.

Moreover, fat dissolving injections or Aqualyx can be used to treat tiny pockets of fat that are resistant to exercise. These include those around the chin, chest, belly, thighs, knees, and ankles. Fat dissolving injections are quite efficient for body sculpting. However, it is not a weight loss procedure.


Fat transfer as a volume-enhancing treatment has been around for a while. However, it is the doctor’s skills and expertise that allow for long-lasting, youthful results.
