##Misconceptions about fat grafting

###The effect of fat grafting for the buttocks or breasts

Fat grafting is sometimes performed to fill in depressions in the buttocks or to enlarge the breasts.

However, there are problems with this.

In the case of the buttocks, it is an area that must keep moving, so the survival rate of fat is extremely low, and if grafted incorrectly, side effects such as pigmentation may occur.

Fat grafting to increase buttock volume inevitably has limitations.

For breast enlargement through fat grafting, at least about 1000 cc of fat must be harvested, and it is difficult to harvest that much fat.

The reason is that people with small breasts are usually not very heavy, so they often do not have enough fat in the lower abdomen, waist, or thighs from which to harvest it, making it difficult to harvest and graft as much fat as desired.

Also, if a large amount of fat is grafted into the breast area, some of the fat may necrotize, leading to abscess formation or calcification, which can cause hardening as a side effect.

If an abscess forms with pus accumulation, it is quite difficult to treat, and even after healing, it can leave significant aftereffects.

In addition, calcification can become a critical problem because it may prevent cancer from being detected in future breast cancer screenings, so in principle breast fat grafting is a procedure that should not be performed.

There are principles in plastic surgery.

Because both good and bad outcomes must be considered, even if the probability of a bad outcome after surgery is only 1 in 100,000, that is a surgery that should not be done.

Breast fat grafting falls into the category above, so choosing breast augmentation with fat requires careful consideration.

###The theory that fat harvested from the thighs has better survival

The harvest site for fat is not fixed.

If anything, the thighs are not a preferred site for fat harvesting.

The problem is that fat contains a lot of oily components.

Oil is an impurity, so it does not help survival.

After the procedure, there is a lot of bruising and swelling, and until the bruising subsides, you should not walk more than necessary, which can make daily life inconvenient. If too much is harvested, problems such as changes in the shape of the thighs or pigmentation may occur.

The choice of harvest site is not determined solely by survival rate.

You must also consider whether there is enough fat, the convenience of harvesting, postoperative swelling and pain, the degree of bruising, how easily one can return to daily life after harvest, the survival rate of the harvested fat, and the shape of the harvest site and potential future aftereffects.

First, the fat must be harvested from an appropriate area for fat grafting.

The harvest site is chosen based on the amount of fat that needs to be suctioned. When only a small amount is being grafted, such as for the under-eye area, nose, or nasolabial folds, the lower abdomen is usually the most common harvest site.

The lower abdomen is preferred because it is easy to harvest from, postoperative swelling and pain are mild, and daily life is more comfortable.

If a large amount needs to be grafted, such as for the cheeks or forehead, it is necessary to check whether enough fat can be harvested from the donor site.

If there is a lot of excess fat in the lower abdomen, it is harvested there. If there is little fat in the lower abdomen, or if the abdominal fat has lost much of its elasticity due to aging or childbirth, it cannot be harvested even if there is plenty of fat.

This is because the abdomen may sag after fat harvest.

In such cases, fat is harvested from the thighs. The thigh is divided into the inner, outer, and back portions when deciding the harvest site, and fat is harvested from the area with the most excess fat.

Fat is carefully suctioned so that no deformation or hollowness occurs at the harvest site.

In some cases, if the person undergoing the procedure specifically wants a particular area, fat may be harvested from the desired site whenever possible.

Because the areas with excess fat and body types differ from person to person, the most appropriate fat harvest site should be determined according to the individual's body characteristics and constitution.

The survival rate is not determined by which area the fat was harvested from.

To achieve good results from fat grafting, the entire sequence of the procedure must be carried out properly: precise harvest, proper purification such as oil removal, pre-treatment of the graft site, evenly grafting an appropriate amount of fat to the site, and grafting in a way that makes the shape natural.

In other words, good results can be achieved only when the entire process from start to finish is performed correctly.

###The misconception that grafted fat flows downward or moves

Fat is a graft of solid cells.

It either survives and remains as your own cells, or it is absorbed and disappears.

Solid cells do not move or flow downward.

There are cases where unlicensed procedures inject industrial silicone or paraffin into the face carelessly, and because these are liquid substances, they mostly flow downward with gravity.

Liquids can move by seeping between cells.

Some people see or hear about side effects from unlicensed procedures and develop a bias, incorrectly assuming that fat grafting can also cause problems. But solid fat cells remain in the place where they were grafted and cannot move to other areas.

Sometimes at other clinics, too much fat is grafted or it is grafted into the wrong area, making the shape look awkward or sagging. Looking at that, one might think the fat has moved, but it has not actually flowed or moved; rather, the graft itself was done incorrectly, or too much was grafted, causing it to look saggy due to the weight of the fat.

###The theory that the purification process must block exposure to air

Fat grafting cannot afford to neglect any step, and the purification process is no exception.

Fat purification is performed to remove all unnecessary impurities other than fat cells.

Impurities removed during centrifugation include water, anesthetic, serum, and red blood cells.

What cannot be purified away during centrifugation is the oil component within the fat cells themselves.

Oil is one of the impurities that must be removed from fat cells and makes up a significant proportion.

It is distributed both inside and outside the fat cells, so the fat cells can be considered entangled with oil.

The only way to remove the oil is to wrap the fat, after centrifugation, in sterile gauze and remove it through natural absorption. At this point, the fat is exposed to the outside.

Some claim that if fat is exposed to air, the risk of infection rises or the fat is damaged by oxidation, but in reality such effects are almost nonexistent.

Under a microscope, fat cells are surrounded on both the inside and outside by a thick oil film, so the fat cells themselves cannot directly contact the air.

In addition, because diluted antibiotics are applied to the fat during the gauze purification process, bacterial infection can actually be prevented more effectively.

###Misconceptions and truths about the long-term effect of fat grafting

Even though many clinics perform fat grafting, only a few can produce proper results.

If fat grafting is not done properly, it can produce results worse than if it had not been done at all.

In principle, fat grafting can produce good results only when performed accurately.

The method differs from clinic to clinic, and experience makes a big difference.

The survival period for fat is about 3 months.

Fat that survives beyond that point remains permanently as your own fat cells.

Some people mistakenly think that grafted fat disappears after 1 or 2 years and returns to the original state, but once fat has survived and taken hold, it does not disappear without reason.

Also, the reason for doing a second procedure after 3 months is to perform it after the fat from the first procedure has fully survived and settled, so that the shape can be assessed before treatment.

During the roughly 3 months it takes for fat grafting to survive, some of it may be absorbed, but fat that has survived beyond 3 months is no longer absorbed and remains permanently as your tissue.

However, the shape of the grafted area does not last forever.

As people age, the skin sags, wrinkles form, and skeletal structure changes, so the area that received fat grafting is not exempt from aging.

For that reason, the effect of fat grafting is sometimes described as semi-permanent, but it is also described more strictly as permanent.

There is a difference in wording, but it can be said that the effect lasts until significant aging progresses later in life.

##Frequently asked questions and answers about fat grafting

###What kind of anesthesia is used for fat grafting, and is there pain?

All fat grafting is performed under painless sedation anesthesia with local anesthesia.

Sedation anesthesia is not general anesthesia; it is anesthesia that maintains sleep for about 5 minutes only to eliminate pain while local anesthesia is being administered.

Therefore, you do not need to worry about pain.

###How does the fat grafting procedure proceed?

All fat grafting is performed under painless sedation anesthesia with local anesthesia.

From fat harvest to purification and grafting, every step is performed delicately and accurately.

For fat harvest, living fat is collected with minimal damage, and in order to concentrate the fat to nearly 100%, it goes through centrifugation and oil and water removal steps.

Also, before fat grafting, subcutaneous tunneling is performed to secure space for the fat to be grafted.

When grafting the fat, microfat grafting is also used to maximize survival.

The procedure may take as little as 20 to 30 minutes, and if multiple areas are treated at once, it may take more than 2 hours.

You can go home immediately after the procedure.

###From which area is it best to harvest fat?

First, fat must be harvested from an appropriate area for fat grafting.

The harvest site is chosen based on the amount of fat that needs to be suctioned. When only a small amount is being grafted, such as for the under-eye area, nose, or nasolabial folds, the lower abdomen is usually the most common harvest site.

The lower abdomen is preferred because it is easy to harvest from, postoperative swelling and pain are mild, and daily life is more comfortable.

If a large amount needs to be grafted, such as for the cheeks or forehead, it is necessary to check whether enough fat can be harvested from the donor site.

If there is a lot of excess fat in the lower abdomen, it is harvested there. If there is little fat in the lower abdomen, or if the abdominal fat has lost much of its elasticity due to aging or childbirth, it cannot be harvested even if there is plenty of fat.

This is because the abdomen may sag after fat harvest.

In such cases, fat is harvested from the thighs. The thigh is divided into the inner, outer, and back portions when deciding the harvest site, and fat is harvested from the area with the most excess fat.

Fat is carefully suctioned so that no deformation or hollowness occurs at the harvest site.

In some cases, if the person undergoing the procedure specifically wants a particular area, fat may be harvested from the desired site whenever possible.

###How many fat grafting sessions are usually needed?

Depending on the area, satisfactory results can sometimes be achieved with just one session.

The survival rate of fat differs by area, there are individual differences, and if the result after the first session is satisfactory, a second session may not be necessary.

In the case of the cheeks, because the survival rate is relatively good at about 50 to 70%, a slight overcorrection is often done in the first procedure, and in most cases a second procedure is not needed.

For the lips or nose, the survival rate is about 30 to 50%, so a second procedure is usually needed.

Because survival rates differ by area, there are individual differences, and the level of satisfaction varies, the number of procedures depends on the situation.

On average, satisfactory results can be achieved with one session, or at most two.

###How much swelling and recovery time follow fat grafting?

Swelling and bruising vary depending on the area and the individual's constitution.

The area with the most swelling is the lips, and the area with the most bruising is under the eyes.

The areas with little to no swelling or bruising are the bridge of the nose, the temples, and the forehead.

In general, it is not very common for fat grafting to cause significant swelling or bruising.

On average, mild awkward-looking swelling subsides over about 1 to 2 weeks.

The recovery period can be thought of as about one week, during which swelling and bruising are present.

###Does the second fat grafting procedure absolutely have to be done after 3 months?

Can it be done earlier or later?

The second procedure is not mandatory and is performed only when needed.

On average, the second fat grafting procedure is scheduled after 3 months.

The reason is that fat survival occurs over about 3 months, and after 3 months there is almost no change in appearance, so the need for a second fat graft can be determined accurately based on the shape at that time.

Another reason is that if the second fat grafting is done too soon, the fat grafted during the first procedure may be damaged during the second procedure before it has fully survived.

There is no problem with doing the second procedure 5 or 6 months after 3 months have passed.

However, after 10 months the stored fat is discarded, so receiving the second fat grafting within 10 months makes the procedure more convenient.

If the second procedure is done after 10 months, new fat will need to be harvested again.

###How long do the effects of fat grafting last?

Some of the fat may be absorbed until about 3 months, but fat that survives beyond 3 months is no longer absorbed and remains permanently as your own tissue.

However, the shape of the grafted area does not last a lifetime.

As time passes and you age, the skin sags, wrinkles form, and skeletal structure changes, so the area that received fat grafting is not exempt from aging.

For that reason, the effect of fat grafting is sometimes described as semi-permanent, but more precisely it can also be called permanent.

Although the wording differs, the effect of fat grafting can be considered to last until significant aging occurs later in life.

###What is the difference between fat grafting and microfat grafting?

Fat grafting is a general term used to cover the whole process of harvesting fat and transferring it to the area to be grafted.

In other words, taking fat in a lump and grafting it surgically is also called fat grafting, and harvesting it with a syringe and grafting it with a syringe is also called fat grafting.

Microfat grafting is a method of fat grafting that uses a syringe. To increase survival, even if the same amount is grafted, small amounts are placed in multiple sites in a grain-of-rice size, depending on the area, to improve precision and survival rate.

###What is the difference between 2D fat grafting and 3D space fat grafting?

So-called 3D fat grafting means grafting fat evenly into multiple layers.

Under the skin there are several tissue layers, including the fat layer, muscle layer, and periosteal layer.

3D fat grafting refers to grafting fat evenly into these multiple layers so as to maximize use of space, increase survival, and allow for soft and uniform grafting.

2D fat grafting means grafting only into one layer among the multiple layers, such as the muscle layer or the fat layer.

However, not all 3D fat grafting is good.

Depending on the area to be grafted and the amount to be grafted, some areas require 3D grafting while others require 2D grafting.

For example, the upper eyelid should be grafted under the muscle layer, and if it is grafted 3-dimensionally, the shape becomes uneven and the eyelid becomes heavy, which can cause side effects.

Therefore, for the upper eyelid, 2D planar fat grafting, where fat is grafted only into the fat layer, is better.

In areas such as the chin or cheeks, if a relatively large amount is grafted, 3D fat grafting is preferable because evenly grafting into the muscle and fat layers creates a softer shape and helps survival.

It is important to choose the appropriate method for each area.

###How is the procedure done to increase fat survival?

To increase fat survival, the harvest process is first important.

Fat should be harvested carefully so that the fat cells are damaged as little as possible and so that impurities are filtered out as much as possible.

To do this, fat is carefully harvested using a small liposuction cannula, and the harvested fat is centrifuged for only about 3 to 4 minutes at an appropriate speed.

Also, after centrifugation, the fat goes through a second purification process in which oil and water are removed by placing it on sterile gauze.

Only by going through these steps can nearly 100% concentrated fat be obtained.

Fat must be concentrated to near 100% for good results after grafting.

Even if the same amount is grafted, if 50% of it consists of impurities such as oil or water, the actual amount grafted is effectively only half, so the effect is cut in half.

It is no exaggeration to say that the biggest factor in the success of fat grafting is whether the fat is properly concentrated.

###Is it true that fat grafting is often absorbed and has no effect?

Fat grafting differs in method from clinic to clinic, and the outcome varies greatly depending on skill.

If fat grafting is done poorly and against principle, most of it may be absorbed even after grafting, making the absorption rate so high that it can be almost no different from not having done it at all.

Only when the sequence from harvest to purification to grafting is performed accurately and according to principle can a high survival rate and a smooth, uniform contour be achieved.

###Is it true that the face can become bumpy after fat grafting?

The principle of fat grafting is to achieve a uniform and smooth contour.

If a bumpy side effect occurs, it is the result of incorrect fat grafting that goes against the principles.

There are many causes of bumpiness.

Examples include grafting fat irregularly directly under the skin, grafting too much fat into one area, grafting unevenly by concentrating it in certain areas instead of distributing it evenly, or not performing molding properly after fat grafting.

Therefore, to achieve a uniform and smooth contour, fat should not be grafted too shallowly, it should be grafted evenly and uniformly through microfat grafting, and finishing with molding is necessary to achieve a smooth facial contour correction effect.

###How many times do I need to visit the clinic after fat grafting?

Two days after fat grafting, you visit the clinic to check the progress.

You also visit about twice a week.

If circumstances are difficult or if your home is too far away, you do not necessarily have to visit after the procedure.

The stitches at the fat harvest site can be removed after one week at a nearby clinic, so if you live far away, you only need to come on the day of the fat grafting procedure, and after that you do not have to visit unless you personally feel the progress is not a problem.

###What side effects can occur after fat grafting?

Because fat grafting uses your own fat, unlike commercial filler materials, there are almost no side effects.

Aside from some swelling and bruising after the procedure, it can be said that there are no side effects at all.

Therefore, it can be considered safer than any other type of plastic surgery.

However, this applies only when fat grafting is done properly. If the procedure goes against the principles, side effects can sometimes occur, such as a bumpy shape, hardening due to fat necrosis, inflammation, or an awkward shape due to excessive injection.

###How long can harvested fat be stored?

Any fat left over after grafting is frozen and stored under sterile conditions for 10 months.

After 10 months, the stored fat is discarded.

Because of limits in storage capacity, it is not kept longer than 10 months.

If a second procedure is done within 10 months after fat grafting, the frozen stored fat can be used conveniently. If the second procedure is requested after 10 months, the fat has already been discarded, so fat must be harvested again for the second procedure.

###Is there a difference in results between using stored frozen fat and freshly harvested fat?

If frozen fat is properly stored, the properties of the fat cells hardly change.

Therefore, frozen stored fat shows almost no difference in results compared with freshly harvested fat.

How well fat can be stored is also one of the techniques of fat grafting.

If there is no fat storage technique, it is difficult to store it even for a month.

It also creates the inconvenience and effort of having to harvest fat every time a procedure is performed.

The storage method requires sterile, low-temperature freezing, and to extend the storage period, the fat must be stored after impurities have been removed so that it does not deteriorate.

Usually, fat cells can be stored sufficiently so that they do not deteriorate for up to about 10 months.

If a clinic says that frozen fat deteriorates easily and the procedure effect is reduced, so fat must be harvested again every time, that clinic lacks storage facilities or technical skill to some extent.

In other countries, frozen stored fat is sometimes used for up to 3 years.

###Features and pride of the autologous fat grafting clinic at Duhan Plastic Surgery

All anesthesia is local anesthesia (sedation anesthesia).

Local anesthesia is performed together with sedation anesthesia, and the procedure is carried out without any pain during or after the anesthesia.

It has a systematic and advanced fat grafting system.

To harvest living fat cells and increase purity, centrifugation, purification, and unnecessary oil removal are used to maximize purity.

Before grafting, subcutaneous tunneling is performed at the graft site to secure space for the transplanted area.

Precise grafting is performed using microfat grafting cannulas.

By grafting evenly into multiple layers using a 3D method, survival is maximized and a soft contour is created.

Appropriate and diverse fat harvest sites are selected.

The most commonly used site is the lower abdomen. Because postoperative pain is small, swelling and bruising are minimal, and daily life is more comfortable, it is often the first choice.

The next preferred site after the lower abdomen is the inner thigh, followed by the outer thigh.

If there is not enough fat to harvest from the thighs, the lower buttocks or the flanks may also be used.

There is no fixed rule for which site gives better fat survival.

The results are similar, and although the area with the most excess fat is the ideal harvest site, it is better to decide the harvest site by considering the amount of fat to be harvested and activities after grafting.

The second-stage purification process of the harvested fat maximizes survival as much as possible.

Among the impurities in harvested fat, the largest proportion is local anesthetic, followed by oil.

Other impurities include serum and red blood cells.

In the first stage, the fat goes through centrifugation for about 3 to 4 minutes, then moves on to the second-stage oil removal process.

Oil is removed manually through a natural absorption method.

Through the second-stage purification process, nearly 100% concentrated fat is obtained, maximizing the effect of fat grafting while increasing fat survival as much as possible.

It secures space for fat grafting through subcutaneous tunneling.

Subcutaneous tunneling is the process of securing space in advance in the area where the fat will be grafted, and it is an essential and important step for high survival and uniform grafting.

Using a thin probe, the tissue under the skin is moved repeatedly in a fan-like pattern to create space for the fat.

The effect of subcutaneous tunneling is to increase fat survival and prevent fat from clumping, thereby creating a uniform and smooth contour.

A soft and uniform facial contour can be achieved with 3D microfat grafting.

Although there are exceptions depending on the area, the basic method of fat grafting is 3D.

It is a method of dividing the fat into several layers and grafting small amounts evenly into each area.

Microfat grafting cannulas are used for precise fat grafting.

In the past, methods using fat injection machines pushed fat under the skin under high pressure, which caused various problems.

The absorption rate of fat was high, survival was not consistent, the contour became bumpy, and it was difficult to graft in delicate areas such as under the eyes.

To solve these problems, when performing fat grafting, the fat is transferred again into a thin 1 cc syringe and grafted into the desired area.

The microfat grafting clinic at Duhan Plastic Surgery uses a self-developed microneedle (micrograft cannula).

The microneedle is a special grafting cannula used only at our clinic that enables ultra-precise grafting.

Fat grafting can be performed on the upper eyelid, lower eyelid, forehead wrinkles, glabellar wrinkles, nasolabial folds, and the bridge of the nose, making fat grafting possible in almost all cases except fine wrinkles.

Molding immediately after fat grafting helps create a uniform and smooth facial contour.

Immediately after fat grafting, delicate molding is performed to spread the grafted fat evenly and create a soft shape.

Molding is the final step of fat grafting and one of the most important steps.

Rapid freezing and sterile storage of the remaining fat makes the second procedure more convenient.

If a second procedure is performed 3 months after fat grafting, the remaining fat from the first procedure is used without harvesting fat again.

The fat remaining after the first procedure is rapidly frozen, sterilized, and stored.

At the time of the second procedure, the stored fat is thawed, making the procedure more convenient.

The storage period for fat is up to 10 months, and if you visit within 10 months, the procedure will be performed using the stored fat.

At Duhan Autologous Fat Grafting Center ~

Based on extensive clinical experience and know-how,

we perform multilayer (layer-by-layer) fat grafting.

Fat grafting uses living cells,

so the key is to ensure that fat cells can achieve a high survival rate.

To increase fat survival,

we do not inject a large amount into one place,

but instead graft evenly and uniformly into multiple layers.

Between the skin and the bone there are multiple tissue layers such as the fat layer and muscle layer.

Fat should be injected in a multilayer structure so that it does not overlap between the periosteum above the bone, or between the muscles and the fascia above and below the muscle.

Multilayer fat grafting lasts 3 to 4 times longer than conventional methods,

and fat survival is also higher.

Our fat grafting procedure also includes a process called 'tunneling,'

which allows the grafted area to come into maximum contact with abundant surrounding blood vessels

so that nutrients can be continuously supplied.

Tunneling means

using a microneedle just under the skin

to create a place where the fat can go.

In other words, space is created as if making a tunnel,

and then the fat is injected,

so even after all the fat has been injected,

it does not sag downward due to gravity or become bumpy.

In addition, a delicate injection method allows for customized design.

By thoroughly managing aftercare after fat grafting,

we carefully monitor progress until the fat has fully taken hold.

During the follow-up period, if necessary,

we try to minimize dissatisfaction with swelling-reducing injections,

shape correction, and molding.
