Obtained the Col-fat fat grafting trademark

Col-fat fat grafting is the intellectual property of Duhan Plastic Surgery.

What is Col-fat fat grafting?

Micro fat grafting achieves take after the grafted fat becomes vascularized through capillaries from the surrounding area.

The take process takes at least three months, and during that time some of the fat may dissolve because it is not vascularized,

and some may be lost because it is compressed by pressure from surrounding tissue.

Therefore, there are cases in which volume increase cannot be sufficiently achieved with fat alone.

To compensate for this, collagen is induced to be produced on its own,

which raises the fat graft retention rate while creating youthful, elastic skin

and contours. That is Col-fat fat grafting.

Features of Col-fat fat grafting

1. Supplies serum, which is the source of nutrients in the early stage of fat graft take.
2. Minimizes pressure from surrounding tissue and increases the take rate.
3. Fat grafting is performed evenly, so it does not create uneven contours.
4. Collagen self-production enhances contour correction effects.
5. Tissue and skin gain elasticity, helping correct wrinkles and creating a more youthful appearance.

Procedure for Col-fat fat grafting

[Duhan Plastic Surgery Autologous Fat Grafting] - [Micro Fat Grafting Guide] image 5

At our clinic, the procedure is performed using a micro-needle developed in-house.

The core of the micro-needle is that the tip of the furubu is precisely processed

to induce collagen production during subcutaneous tunneling.

We have also realized ultra-precise fat grafting with the Col-fat technique.

Even in very fine wrinkles or delicate areas such as under the eyes or above the eyes,

it has the advantage of allowing precise treatment in 1 to 2 mm units,

so even the most difficult areas can be treated without problems.

For correction of dark circles under the eyes, a procedure using a micro furubu

can achieve effective dark-circle correction with almost no unevenness.

Through tunneling using a micro furubu and micro fat grafting using a micro-needle,

even the most demanding under-eye procedures can be performed effectively.

Differences between regular fat grafting and Col-fat fat grafting

ComparisonRegular fat graftingCol-fat (Col-fat) fat grafting
ContourUnevenness may occur.No unevenness occurs.
Take patternMay take unevenly.Takes almost evenly.
Collagen productionNo collagen production.High collagen production.
Take rateRelatively lower.High take rate; effective facial contour correction is possible.
Skin elasticityHas little effect on skin elasticity.Skin elasticity increases through collagen production.

Fat grafting for facial contour correction

Fat grafting is also called fat injection.

It refers to drawing fat from one’s own body with a syringe and then injecting it into the desired area with a syringe

to correct the contour of the face.

It is often also called micro fat grafting,

which means a more precise and delicate procedure.

It can effectively correct facial hollows, unevenness, and deep wrinkle lines,

and it is applicable to most areas of the face.

The procedure is simple, there are no side effects,

and it can be naturally corrected to the desired amount in any area,

so fat grafting is one of the effective facial contour plastic surgery procedures.

Areas where facial contour correction is possible with fat grafting

Hollow or asymmetry of the forehead
Hollow or asymmetry of the temples
Thin cheeks or facial asymmetry
Hollow upper eyelids
Hollow or wrinkled lower eyelids
Creating aegyo-sal in the lower eyelids
A low or crooked nose
A face with prominent cheekbones
An inverted triangle face
Multiple depressed scars
Forehead wrinkles, glabellar wrinkles
Nasolabial folds around the mouth

Advantages of fat grafting

Because it uses autologous tissue, there are no side effects at all.
Since there is no incision like in surgery, the procedure is simple.
It is less expensive than other filler materials (Artecoll, AlloDerm, etc.).
It can be performed on any area in the desired amount.
Repeat procedures are possible, and the effects last a long time.

Misconceptions about fat grafting

Some people say that fat grafting is quickly absorbed and therefore has no effect, but this is a misunderstanding.

In principle, fat grafting is effective only when performed properly.

The results vary depending on the practitioner's experience and skill.

From fat harvesting to refining and grafting,

it must be performed accurately and meticulously to achieve good results.

Procedures without principles may have little effect or may even cause side effects.

Proper fat grafting often brings satisfactory results with just one procedure,

and the effects last for a very long time.

Areas such as the cheeks often show permanent effects as well.

Comparison between fat grafting and filler materials

Various filler materials have been commercialized to correct facial wrinkles and scars

and are used in plastic surgery and dermatology.

These include collagen, AlloDerm, Restylane, Artecoll, Juvederm, Aquamid, and Interpol.

These filler materials are mainly used to correct fine wrinkles rather than facial contour.

For facial contour correction, the amount is too small, the price is high,

and because they are used for purposes that do not match their intended use, there is a risk of side effects, so caution is needed.

For facial contour correction, fat grafting can be considered an effective and safe procedure.

At our clinic,

based on more than 20 years of rich 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 the fat cells have a high take rate.

To increase the fat take rate, we do not inject a large amount into one place,

but graft it evenly and uniformly across multiple layers.

Between the skin and bone there are multiple tissues such as fat and muscle layers,

so the fat must be injected in a multilayer structure without overlapping,

such as between the periosteum on the bone and between the fascia above and below the muscle.

Multilayer fat grafting

lasts 3 to 4 times longer than the existing method, and the fat survival rate is also higher.

At our clinic,

fat grafting also includes a process called 'tunneling,' which allows the grafted fat to come into maximum contact with surrounding abundant blood vessels

so that it can continuously receive nutrients.

Tunneling means using a micro-needle just under the skin

to create a place for the fat to go,

literally making space as if drilling a tunnel,

and then injecting the fat afterward, so even after all the fat has been placed,

it does not sag in the direction of gravity or become uneven.

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

After fat grafting, we provide thorough aftercare

and carefully monitor the progress until the fat is fully taken.

If needed during follow-up,

we try to minimize dissatisfaction through swelling-reducing injections, shape correction, and molding.
