AVAN TOKYO’s philosophy on areas that require extreme caution

Facial fat grafting has become increasingly popular for areas such as:

• Forehead
• Temples
• Under-eyes
• Nasolabial folds
• Lips

Fat grafting involves transferring fat harvested through liposuction into another area of the body.

Many people view it as:

“Natural because it uses your own fat”

“A safe way to restore volume”

And in some cases, it can indeed produce beautiful results.

However, at AVAN TOKYO, we believe:

“Facial fat grafting should never be recommended casually.”

The biggest risk: nodules and fat necrosis

One of the most important risks of facial fat grafting is:

“nodules” (fat necrosis / fibrosis)

After injection, fat cells must establish a new blood supply in order to survive.

If they do not,

• fat necrosis
• inflammation
• fibrosis

can occur.

This may lead to:

firm lumps or irregularities.

The under-eye area is especially delicate

At AVAN TOKYO, we are extremely cautious with:

under-eye fat grafting.

In fact, unless a patient has a very strong desire for it,

we often advise against the procedure.

Why?

Because the under-eye area has:

• extremely thin skin
• limited blood supply
• very little margin for irregularities
• difficult revision potential

Even with meticulous technique,

the risk of nodules can never be reduced to zero.

And unlike fillers,

fat cannot simply be “dissolved.”

In some cases, revision may require:

• surgical excision
• aspiration
• direct fat removal

which can be highly challenging.

“Natural” does not always mean “safe”

Recently, many patients assume:

“Because it’s my own fat, it must be safe.”

However, in facial fat grafting,

selecting the right area is critical.

At AVAN TOKYO, we believe that:

“Knowing where NOT to inject”

is just as important as knowing where to inject.

Areas that are generally safer

Areas such as:

• Forehead
• Temples

are often more forgiving because they have:

• thicker skin
• better blood supply
• less visible irregularities

As a result,

nodules are less noticeable and fat survival is often better.

Skin thickness and blood flow matter

In facial fat grafting,

skin quality and vascularity

are extremely important.

Areas such as:

• Under-eyes
• Tear troughs
• Lips

require particularly careful consideration because they are:

• thin-skinned
• highly mobile
• vascularly delicate

In many cases,

avoiding injection may actually be the better decision.

Facial fat grafting is a highly delicate procedure

Fat grafting is not simply:

“adding volume.”

Especially in the face,

even 0.1cc can dramatically change the appearance.

Factors such as:

• skin thickness
• bone structure
• retaining ligaments
• circulation
• facial muscle movement

must all be considered.

In other words,

facial fat grafting is an extremely delicate procedure.

AVAN TOKYO’s philosophy

At AVAN TOKYO, we prioritize:

“long-term natural aesthetics”

over simply adding volume.

For that reason, we may sometimes advise patients that:

“Certain procedures may not be the best option.”

In aesthetic medicine,

proper indication is just as important as technical ability.
