What Should I Know First If I’m Getting Juvelook in Hongdae?

Q. Isn’t Juvelook just a collagen injection? Isn’t it the same no matter where you get it?

A. Even with the same drug, the results differ completely depending on the concentration, the layer it’s injected into, and the thickness of the person’s skin. It’s not the machine—it’s the 'design' that matters.


Q. Why are there so many reviews saying the effects differ even though it’s the same Juvelook?

A. Because if the depth and density at which PDLLA particles settle are different, the collagen-production response itself changes.

What to Know Before Getting Juvelook in Hongdae and Hapjeong—Beauty’s Doctor Treatment Standards

What Is Juvelook?

Juvelook is

a skin booster treatment

that injects PDLLA (poly-D,L-lactic acid)

into the skin

to induce

your own collagen production.

While the commonly compared Sculptra

is based on PLLA and focuses on restoring volume,

Juvelook has smaller particles

and is specialized in improving 'surface texture'

such as skin texture, elasticity, and pores.

Why Results Differ Even With the Same Juvelook

To be honest,

this is a somewhat tricky part.

From a patient’s perspective,

you can’t help but think,

"It’s the same drug, so why are the results different?"

But there’s something important here.

PDLLA particles meet different cells

depending on the depth at which they are injected.

If they go in too shallow,

they can clump or form white nodules

just beneath the epidermis,

and if they go in too deep,

people often don’t really feel the skin-texture improvement.

I usually explain it like this:

"The depth at which you plant a seed

determines the size of the flower."

In the upper dermis,

that is, about 1–2 mm below

the skin surface,

PDLLA particles need to be evenly distributed

so that fibroblasts (the cells that make collagen)

receive the proper stimulation.

This 'proper stimulation'

is actually directly tied to concentration adjustment.

Juvelook’s stock concentration can be

adjusted by the dilution ratio,

but if you use a strong concentration on someone with thin skin,

the risk of bruising or nodules goes up,

and if you use a diluted concentration on thick skin,

the effect is harder to feel.

That’s why before treatment,

I always directly check skin thickness and elasticity

by palpation.

Even with the same Juvelook,

this setup process is what determines the outcome.

One thing many people misunderstand is that

"Juvelook is one and done"

is not true.

As PDLLA breaks down

and collagen gradually fills in,

the skin-texture improvement usually becomes noticeably clear

after 2–3 sessions

spaced 3–4 weeks apart.

From my experience,

among patients who came in saying

"it didn’t work" after 1–2 treatments elsewhere,

a considerable number were cases where the concentration or injection depth

didn’t match their skin condition.

👨‍⚕️ Director Woo Young-jin’s Key Summary:


With Juvelook, it’s less about 'which drug you get'


and more about whether it’s designed with the right concentration and depth


for your skin thickness that determines the result.


That’s where the reason for different outcomes with the same drug lies.

Juvelook Application Criteria by Skin Type

It varies by case,

but this is usually how I divide the approach.

But it’s not all good.

One thing I must tell you is that

Juvelook is not a treatment

where you can expect immediate changes.

Unlike hyaluronic acid fillers,

it doesn’t give a "wow, it’s different!" result right away,

because collagen gradually builds up

over 4–8 weeks.

So for people who need it

to be ready for an event next week,

I honestly recommend a different procedure.

However, for those who want to fundamentally improve

their skin’s own elasticity and texture

over the long term,

it is still a good choice.

It often lasts around 6 months to 1 year,

and I’ve seen quite a few cases where the maintenance period

gets even longer with repeated treatments.

Frequently Asked Questions

Q1. What’s the difference between Juvelook Volume and regular Juvelook?

A. Juvelook Volume

has a higher PDLLA content,

so it provides an effect closer to volume restoration.

Regular Juvelook

focuses on improving surface texture

such as skin texture, pores, and fine lines.

It should be applied differently

depending on the area of concern.

Q2. How much does it cost, and how many sessions are needed?

A. The price per session

varies depending on the product type and amount used,

so we’ll give you the exact information during consultation.

Usually, we set 2–3 sessions as the basic protocol

at 3–4 week intervals

and adjust it while observing the skin’s response.

Q3. Are there any precautions after the procedure?

A. On the day of treatment,

please avoid alcohol, saunas, and strenuous exercise,

and for 2–3 days,

mild bruising or swelling

may occur at the injection site.

In rare cases, if a white nodule is felt,

light massage usually helps it

absorb within 1–2 weeks.

However, if it lasts more than 2 weeks,

please be sure to have it checked

at the clinic where you received the treatment.

I recommend consulting thoroughly before deciding on the procedure.
