"Consultation with the head doctor,

but the procedure done by someone else?"

Before getting filler in Hongdae,

the 'treatment structure' you must verify

"Doctor, after seeing the news, I'm scared to get fillers."

These words I hear as soon as the consultation room door opens

make me feel a great sense of responsibility as a doctor these days.

It's hard to treat fillers as just a 'volume injection'

when there are so many medical variables to consider.

Today, I want to share what will turn your anxiety into confidence:

the real standards of filler procedures.

💡 Key summary of today's post

Q. Are there places in Hongdae where the head doctor

personally performs the procedure?

A. Yes, there are. But don't just trust the wording—

you need to verify the treatment structure yourself.

Q. Are there differences between products?

A. Viscosity and cross-linking methods vary across products,

so there are specific products suited to each area.

Q. What is the most common

side effect?

A. Bruising and swelling are common,

but vascular compression, though rare, is the most dangerous.

That many filler

products exist?

Fillers are broadly divided into hyaluronic acid (HA) types

and collagen stimulator types.

Even within the same HA category, each product has

different viscosity (G prime) and cross-linking density.

For thin areas like under the eyes, a softer product is used;

for areas requiring support like the chin or nose,

a firmer product is needed.

This choice is not simply about a brand name—

it is

a medical judgment that must account for anatomical structure.

Procedures performed directly by the head doctor—

why does it matter?

To be honest, in some large clinics,

there are cases where non-doctor staff

administer fillers.

Just because a clinic has a big name

doesn't mean the head doctor performs the procedure personally.

Because fillers are injected into areas rich in blood vessels,

an inexperienced approach can lead to vascular compression

or embolism risk.

Especially for nose, under-eye, and forehead fillers,

I always emphasize in advance that

an experienced doctor must perform them directly.

During your consultation, make sure to ask: "Who will personally perform today's procedure?"

Please don't skip that question.

👨‍⚕️ Dr. Wi Youngjin's Practical Note:

In my experience, patients who return to our clinic

dissatisfied with results from elsewhere

often never asked during their consultation whether a

cannula (a blunt-tipped needle) would be used.

Of course, a cannula isn't always the right answer,

and depending on the area, a regular needle may be more appropriate.

One thing you must remember!

HA fillers can be dissolved,

but there is no way to dissolve non-HA types.

So for first-time patients,

I recommend starting with an HA type.

Choosing the right filler by treatment area

It varies by case,

but here is what I typically recommend.

• Under eyes: Low-viscosity HA filler, injected in very small amounts

• Nasolabial folds: Medium-viscosity HA filler

• Nose/Chin: High-viscosity HA, focused on support and definition

• Forehead: Medium-low viscosity filler, targeting the layer above the periosteum

Even with the same "filler procedure,"

the doctor's judgment must be continuously involved depending on the area.

Key takeaway:

More than the product itself,

the practitioner's anatomical judgment is what matters.

Always confirm whether the head doctor performs the procedure directly.

Post-procedure care—

just follow these steps

For the first 48 hours after your procedure,

avoid pressing or rubbing the treated area.

Especially if you had nose filler,

be careful about wearing glasses for at least 2 weeks.

Dr. Wi Youngjin makes every effort to minimize bruising and swelling

by using cannulas as much as possible,

but bruising can still occur depending on vessel location.

I want to be upfront with you about that.

Frequently Asked Questions (FAQ)

Q1. Does the head doctor really

inject personally?

A. Yes, I perform all procedures directly near Hapjeong Station.

The most accurate way is to confirm the treatment structure

in advance by phone or KakaoTalk.

Q2. How long does it last?

A. HA types typically last between 6 months and 1.5 years.

If your metabolism is fast or you exercise frequently,

it may break down sooner.

Q3. What if I don't

like the result?

A. HA types can be dissolved with a dissolving injection (hyaluronidase).

However, non-HA types cannot be dissolved,

so be sure to confirm the product before your first procedure.

If you have any questions,

feel free to reach out via KakaoTalk.
