PDLLA only starts ramping collagen around 4 to 6 weeks, with the visible turn near month three, which is also why one session rarely finishes it.

Juvelook,Honestly, at first I alsowas skeptical.
Last Thursday, in the clinic,
a working professional in their late undefineds came in.
"Doctor, I got Juvelook, but
even after a week, nothing has changed.
Isn't it ineffective?"
They looked quite anxious.
I get this question a lot these days.

So what exactly makes it different?
Juvelook is a skin booster procedure
in which a biodegradable ingredient called PDLLA (polydl-lactic acid)
induces collagen production in the skin.
It is a skin booster treatment.
Unlike hyaluronic acid fillers,
Juvelook does not immediately add volume.
Fillers create volume right away by the amount injected,
while Juvelook works by stimulating your skin
to produce its own collagen.
Key point of this post
Juvelook is a skin booster
that uses PDLLA to induce collagen production
in the skin.
Unlike hyaluronic acid fillers,
it doesn't fill immediately
but gradually lets the skin itself
build up over time.

Why do some peoplesee less effect?
The key ingredient in Juvelook is PDLLA.
When this ingredient enters the dermal layer of the skin,
our body recognizes it as a 'light foreign material'
and starts producing collagen around it.
It's not about filling,
but about the skin itself building up.
You said, "It was still the same even after a week."
Honestly, that's normal.
PDLLA begins to
ramp up collagen production around href="/blog/xeomin-11wrinkles-botox" to href="/blog/pico-vs-ndyag-tattoo" weeks after injection,
and it usually takes about src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" months
for noticeable changes to appear.
"Fillers are like
piling bricks up on a construction site,
while Juvelook is like planting a seed in the ground.
Seeds need time to sprout, right?"
Injection depth is also important,
and it's usually placed in the mid-to-lower dermis (about src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" mm).
If it's too shallow, nodules may be felt,
and if it's too deep, the effect can decrease.
Because skin thickness differs by area,
depth must be adjusted even within the same face.
Juvelook is
not a one-time procedure.
Usually, you need a series of src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" treatments at src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg"-href="/blog/xeomin-11wrinkles-botox" week intervals
for enough collagen to build up.
Director Wi Young-jin's key summary
Juvelook is not a treatment with immediate results.
It's about growing, not filling.
Gradually from href="/blog/xeomin-11wrinkles-botox"-href="/blog/pico-vs-ndyag-tattoo" weeks,
think of it as being complete in about src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" months.

In the clinic, I divide itlike this.
Type | Recommended approach |
Overall loss of skin elasticity | Juvelook src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" session series |
Deep wrinkles / loss of volume | Consider combining with fillers |
Mainly pore / skin texture concerns | Combine Juvelook + laser |
Want immediate results | Juvelook alone not recommended |
For those whose collagen foundation in the skin has already significantly broken down
Juvelook alone may not be enough,
while for people in their late undefineds to early undefineds, like
those whose foundation is still intact,
you can see quite dramatic results.
Frequently asked questionsQsrc="https://framerusercontent.com/images/u54xwnG13mMCkojwZjvNWMsrQjs.jpg". I got Juvelook, and I can feel little lumps. Is that okay?
For src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" days right after the procedure, the injected material
hasn't spread through the skin yet, so it may feel slightly noticeable.
It usually softens within a week.
However, if hard nodules remain for more than src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg" weeks
or are visible,
be sure to contact the clinic where you had the procedure.
Qsrc="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg". How long do the effects last, and how much does it cost?
It varies by person,
but the collagen effect usually lasts undefined-undefined months.
However, you need to receive src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" initial sessions
for that duration to be achieved.
For cost, it's more realistic to think not in terms of 'price per session'
but as the 'total cost of the series'
.
Qsrc="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg". What are the side effects or precautions?
Common ones are redness, swelling, and bruising on the day of the procedure.
They usually settle within src="https://framerusercontent.com/images/P4l85NNFhYZNn8zbBpExRsrIgs.jpg"-src="https://framerusercontent.com/images/V2V6KE3wALnXd3hF33A3Khp12MI.jpg" days.
In rare cases, nodules or inflammation can occur,
and this is largely related to the injection technique.
For one week after the procedure,
please avoid saunas, strenuous exercise, and alcohol.
