Your doctor will inject fat under your skin between the buttocks. Lumps after fat transfer are normal and after a few weeks, they will shrink as the area around them fills with fluid. The fat cells will then die off and be replaced by new cells from your body. Generally speaking, you can expect to start seeing results in about two months.
This is one of the only treatments that can have immediate results, but you have to be patient and allow a period to pass before you can expect to see any results. Whenever you boost in fat or cellulite, it will naturally start fading away. You can use products like high-end cosmetics available in salons or boutique stores if you want to stay within the aesthetic expectations.
The treatment is generally safe, but like with any cosmetic procedure, there are risks involved. If you are not accustomed to going under the knife, be sure to relax and seek the advice of a medical professional.
The recovery period is highly predictable in that it takes two weeks for the fat to fill up the area where it was injected. There is also a three-month post-scar period after which you should see some results based on your body chemistry and skin type. More importantly, however, this procedure is painless.
The most common risks associated with this surgical procedure are the possible retention of localized fluid which may occur at a rate of 1%. This leads to an accumulation of fluid and redness in the area that was injected. There is also a minimal risk of infection and pain during recovery. In addition, there is a small risk for lumpiness, which plumps up slightly over time but does not disappear completely.

Body contouring and fat transfer procedures are done to help people who have lost weight regain a more pleasing appearance. Body contouring, also known as liposuction, involves the removal of excess fat through small incisions while fat transfer involves taking lipoaspirate from one area and injecting it into another.
Recovery time for both types of procedures will vary depending on the amount of work done and your health.
If you have undergone a fat transfer procedure, the recovery period will vary depending on both your body and the type of procedure. Liposuction recovery times are usually shorter than fat transfer recovery times because lipoaspirate is removed from the body and then injected directly into it. The fat transfer takes longer because the tissue is first removed from one area of your body, processed, often frozen, and then reinjected at another site.
Depending on the type of procedure you had and the amount of fat transferred, you may be able to return to your normal activities immediately following your surgery. Pain medication and local anesthesia will help you cope with discomfort during recovery.
Numbing is usually given by injection into the skin following surgery and can make you feel young again quickly. A local anesthetic is usually given as a pill before your procedure, so it should be easy to take under normal circumstances.
First, you should see your doctor rule out any serious problems. If the problem has been diagnosed, then you can go home or to a rehab facility where medical staff will monitor your condition.
Although recovery is possible after fat transfer procedures, it may take longer. Doctors often recommend further recovery time in a rehab facility or at home to heal the area and allow the skin to completely heal.

When a fat transfer is completed, the recipient’s body will absorb and use the fat cells. Time-dependent dyeing can be used to determine when cells are taken up by the recipient. In this procedure, a pigmented dye is injected into one of the donor sites, and after 6 hours it is visible on all parts of the body in which fat was transplanted. This technique enables plastic surgeons to monitor patient response following plastic surgery more accurately than with traditional imaging techniques. This process is critical during the first week after fat grafting to ensure the grafts are surviving.
There may be a fever or increased blood pressure in the patient at the time of the dyeing. During this time the grafts should be monitored closely. It is important to monitor the color change of these grafts, as it can be used as evidence against any type of activity that may damage them. Immediately post-surgery (within 24 hours) patients should have 3 blood tests: complete blood count, liver function test, and selected metabolic panel (if applicable). It is important to determine early on if the patient developed any complications following the surgery, such as infection, bleeding, or ulceration.
By postoperative day 2, the recipient should be able to walk and return to their normal activities without pain. The amount of swelling in donor sites is noticeable by Day 3 and will gradually diminish by Day 5 post-surgery. Most people report feeling soreness at donor sites after 4 to 6 days. Within a few days after surgery, patients start to feel more comfortable and able to move around. Within the first 2 weeks, patients should be able to resume normal activities. Fat transfer recovery process:
Once fat cells begin to show up in the recipient’s body (about 1-week post-surgery), you should be able to see the amount of fat leaving the donor sites by utilizing an ultrasound scan or other imaging techniques. It is important to monitor any decreased or increased swelling in the donor sites and treatment plan accordingly.
Once the recipient develops a little bit of tolerance (approximately 1-to-3 months post-surgery), they can begin to exercise and start increasing their daily activities. It is important to continue to avoid strenuous exercise in the areas where fat was transplanted and avoid exertion, since this may cause the fat cells to break down faster.
After 4 weeks or so, patients can begin taking medications (such as aspirin or other NSAIDs) if needed.
