MD Code Filler,

I was late to realize that

only 8 points matter

When the face sags, it’s easy to think

filler should be spread broadly.

I used to wonder whether that was really right, too,

but after doing a few hundred cases,

I learned something important.

MD Code Filler works on a principle

similar to a tent pole.

Rather than pulling the entire canopy by hand,

you need to set up a few support points for the shape to hold.

What makes MD Code Filler different?

It is a method that deeply supports strategic points.

If standard filler is closer to

simply filling a sunken area,

MD Code first looks at the structural axes that support the face.

It’s not just about the cheek area where the hollow is;

we also look at support from the temple, outer cheekbone, and back cheek.

It’s not about injecting a large amount no matter what,

and in some cases the amount needed can actually be reduced.

The key is where the filler

is placed in depth.

That’s because the deep support layer is close to

the structure above the bone and can

serve as a stable foundation very well.

Why does MD Code Filler

sometimes look deformed or migrated?

Dr. Wi Young-jin's key insight

MD Code is not about spreading filler

across the entire face, but about placing

'stakes' at 8 to 10 strategic points.

Even if you fill only three areas—the front cheek, temple, and back cheek—

facial sagging can be improved.

When filler looks off, deformation and migration

do not mean the same thing.

Deformation means it stays near the original spot,

but the shape looks compressed or lumpy.

Migration, on the other hand, means it has

been pushed from the intended location

into a different tissue space.

In many areas of the face, the skin thickness is around

1 to 2 mm.

If it is spread shallowly and broadly, it can look puffy,

whereas a small amount placed at a deep support point

can make sagging appear less noticeable.

Last week, for a 32-year-old patient, I also recommended

re-marking only the necessary points

before filling broadly.

That’s because MD Code Filler is not about increasing

the total amount, but about precisely

choosing the support points.

Dr. Wi Young-jin's key summary

MD Code Filler is not a method that

makes the entire face thicker.

The goal is to set only the necessary support points,

and first distinguish

whether it is deformation or migration.

Warning signs of vascular issues should not be waited on;

they are emergency signs that need immediate attention.

Which types need

extra caution for vascular occlusion?

Changes in skin color and pain should be checked immediately.

In particular, for repeat procedures, previous filler may still remain,

so the shape of the new filler

can turn out differently than expected.

Areas with delicate vascular connections, such as

around the nose, between the eyebrows, and around the eyes,

should be judged more conservatively.

If you notice vision changes, severe pain,

or a rapid change in skin color,

contact medical staff right away.

The key to emergency response is never

to waste time.

Three questions to ask before MD Code Filler

Q1. Do I need filler across the entire face?

Injecting a thin layer everywhere does not necessarily

make it look natural.

When the necessary structural axes are supported,

overall sagging looks improved.

Q2. How long does it last?

Deep support points tend to hold up longer, but

areas that move a lot may feel like they fade

more quickly.

In many cases, it is not that the filler has completely disappeared, but that the support

structure has changed.

Q3. Can vascular occlusion be recognized right away?

It is truly rare, but if you suddenly feel severe

pain or the skin turns pale,

do not wait—get it checked immediately.

If it is a hyaluronic acid filler,

rapid response is the most important thing.

If you take away just one thing today,

— before the amount of filler, first check the few

axes that support the face.

In the next article, I’ll explain how to

actually distinguish filler deformation from migration.

This has been Dr. Wi Young-jin.
