Do Fat Injections in Your Buttocks End Up Fading?

A doctors office told Me that fat injections end up fading and people nationwide are unsatisfied with fat injections because of this. I have also read about a lot of different silicone injections fading or scary stories of people saying this was the worst decision they made because of all the side effects. Do these injections fade away and are they safe?

Silicone injection to the buttocks

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

First I disagree with the surgeon's office who told you that fat transfer to the buttock ( Brazilian Butt Lift) will diappear.

That is FALSE, fat transfer is the best way to enhance a buttock now.

As for silicone injections to the buttocks. These are being done in motels and basements by non physicians and they use either commercial grade silicone( from the hardware store) with disasterous results. or use commercial hydrogell used in potting plant.

The body reaction to iinjectable silicone is Granulomas that are hard, painfull and may have chronic infections with strange bacteria. It is an illegal trade, that is why it is done in basements and motels.

Removal of the injected silicone is very expensive and very difficult, and one is not possible to remove ALL the silicone.

What Happens to Fat transfers (Butt, Face, Hands etc)

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Living fat is NOT a shapeless gel, it is a collection of living cells which requires a good circulation to deliver oxygen and nutrients and remove degradation by product. The harvesting of fat involves suction and injures a variable percent of the fat cells so not the fat removed contains intact living fat cells. In addition, the processing of the fat and the placement of fat in the area to be grafted result in further injury and cell death. Finally, once transferred, those fat cells which are not rapidly supplied by blood vessels will not make it as we.. As a result, a variable portion of the fat transferred will not survive the collection and transfer process. However, UNLIKE all other fillers, your own fat lives forever and has NONE of the serious complications seen with permanent fillers. There is no better filler for filling large areas.

Fat injections to the buttocks provide long lasting benefits

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Fat injections to the buttocks provide long lasting benefits. Up to 50% of the fat can survive for many years. With aging, touch up procedures also help. New research into the use of stem cells will increase the longevity of fat transplantation in the future.

Fat Injections

Fat grafting is still a relatively new procedure.  Typically a patient can expect about a 25-45% volume loss after grafting or a 55 - 75% take.  And that is with a well done procedure and following your post-op instructions.  It is very important to minimize your time that that the buttock is dependent (sitting or laying on your butttocks) to 10-15 min at a time for 2 full post-op weeks. The results should be permanent after the initial volume loss if you maintain your weight.  I would strongly recommend against having large volumes (the volume necessary to increase your buttock size) of silicone injected anywhere in your body!

You need to have an accurate pre-op assesment and discussion of what volume of fat you'll require and what volume you have available to graft.

Hope this helps

Fat transfer to buttocks

some of the fat will get reabsorbed but whatever fat survives will be permanent. There may be changes of course as you age but that happens with everyone.

Fat transfer is permanent

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Fat transfer well done with my technique would have amazing results that are permanent.  I was trained in Brazil where this procedure is routine.  The cost is $4800

Fat grafting will fade

Unfortunately, transferred fat volume most definitiely diminishes with time.  I counsel my patients that expect 50% of the fat volume to be lost over five years.

It is true that some of the fat that is injected does not stay.  However, a good portion of it usually lives.  If necessary, a secondary "touch-up" procedure can be done as well.

Fat is a permanent plumper for the buttocks

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Fat transfer (taking fat from one place in the body and moving it to another) is a great method for increasing volume of the buttocks.  It is true that some fo the fat does not survive the transfer.  Even int he best hands, approximately 30-50% of the fat that is transferred will die and will be absorbed by the body. This usually happens within the first 3 months and is the reason why people say that the fat "does not stay."  The remaining 70-50% of the fat will survive and even grow.  This is a safe way to increase the size of the buttocks and give a lift....when done by someone experienced with the technique.

Fat Injections Are Good, Silicone Bad

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

In general, fat injections into the buttocks are permanent once the initial fat becomes incorportaed into the surrounding tissues.  In some patients, this is all of the fat while others it is only 50%.  This is why some patients need multiple treatments.  But, once that fat is living there, then it should be permanent.  Silicone injections are not recommendedfor any part of the body.  It is illegal to inject silicone and there is no such thing as medical grade silicone, no matter what you may see advertised.  I hope this helps
