Does Juvelook actually work? What changes?

Juvelook is made of a material called PDLLA. It is injected into the dermis or the fat layer under the skin, where it increases collagen and elastin production to firm the skin and fill in lost volume. As the skin fills out, fine lines, pores and depressed scars can gradually improve, and a sagging, hollow face can look firmer and fuller. Rather than an instant change, it improves slowly over weeks to months and can last a relatively long time. Patients are most satisfied when we clearly explain the difference between Juvelook Skin and Juvelook Volume, and which product suits which case and area.

How many sessions do I need, and how far apart?

In studies, two to three sessions four weeks apart made up one course. Collagen takes time to form, so changes continue for several months after the first course, and maintenance is planned afterwards depending on your skin. We usually do about three sessions roughly four weeks apart, check progress, then plan what comes next.

What is the difference between Juvelook and Juvelook Volume?

They are the same family. Juvelook (Skin) is used for the skin itself, such as texture, fine lines and pores, while Juvelook Volume has a higher PDLLA content and is mainly used to gradually fill hollow areas. The product and injection depth depend on the area and your concern. For skin texture and firmness I recommend Juvelook Skin, and for lost volume, Juvelook Volume.

Are there side effects? Can it cause lumps or nodules?

Common reactions are swelling, bruising and small raised bumps. Depending on the area, a small palpable nodule can rarely form, so we do not inject close to the under-eye area and we carefully control depth and amount. Done this way, the risk of side effects can be greatly reduced. As a rule, we never inject close to the under-eye area.

Juvelook or Rejuran, which should I get?

If your goal is texture, recovery and fine lines, consider Rejuran. If you want to gradually fill hollow areas and stimulate collagen for firmness, consider Juvelook. Some people alternate them or plan both. For skin firmness and ageing I usually recommend Juvelook Skin first, and for skin that has become sensitive from frequent treatments, Rejuran first.

Key points

Juvelook is a skin booster that combines microspheres of PDLLA (poly-D,L-lactic acid), a biodegradable polymer, with non-crosslinked hyaluronic acid. Its aim is to stimulate new collagen.
The PDLLA particles are porous spheres averaging about 27 µm. A 2024 consensus paper reports myofibroblasts among the spheres at around 2 weeks, type I collagen between and on the spheres at around 4 weeks, and collagen inside the particles at around 20 weeks.
In a Korean study (16 participants, 2–3 sessions 4 weeks apart), fine wrinkles, texture, pigmentation and redness improved significantly, biopsies showed more dermal collagen and elastic fibres, and there were no serious adverse events.
Because PDLLA breaks down slowly and collagen forms during that time, results appear gradually over weeks to months rather than immediately.
Juvelook (Skin) is mainly used for texture, fine lines, pores and shallow scars; Juvelook Volume contains more PDLLA and is mainly used to gradually restore lost volume.
Common reactions are swelling, bruising and small raised bumps at injection points. Small palpable nodules can occur rarely, and injection into a blood vessel can rarely cause blood-flow complications.
Dr. Park's clinic usually plans about three sessions roughly four weeks apart and does not inject close to the under-eye area.

Juvelook is a Korean skin booster that places tiny PDLLA microspheres, together with hyaluronic acid, into the skin so that your own collagen slowly builds up around them. It is not a filler that adds volume on the spot: results appear gradually over weeks to months, and because the collagen is your own, they tend to last relatively long.

Juvelook at a glance

Best for: thinning skin and lost firmness, fine lines, enlarged pores, shallow acne scars; Juvelook Volume for gradual soft volume
Sessions: usually about 3, roughly 4 weeks apart
When you see it: gradually, over weeks to months
Not for: filling a deep hollow in one go; Dr. Park's clinic does not inject close to the under-eye area

How does Juvelook work?

Thin skin, a hollow cheek and shallow scars (before) → PDLLA particles go into the cheek dermis, avoiding the area right under the eye (injection) → small bumps right after that settle within days (right after) → over months collagen builds, so the hollow and scars look less obvious (months later).

The circle shows the porous particles, about 27 µm on average. Illustration of the mechanism.

Injection: PDLLA microspheres and hyaluronic acid go into the dermis, or into the fat layer for volume. The gel adds early hydration and helps the particles spread evenly.
Stimulation: as the body slowly breaks the particles down, fibroblasts around them switch on.
Rebuilding: new collagen and elastic fibres fill in, so the dermis becomes denser and texture and firmness improve.

The particles do not dissolve all at once. They break down slowly from the inside over months while collagen takes their place, which is why changes are gradual and relatively long-lasting. In a Korean study, biopsies after 2–3 sessions showed more dermal collagen and elastic fibres, and fine wrinkles, texture, pigmentation and redness improved. The studies are small, so larger trials are still needed.

Juvelook vs Juvelook Volume

	Juvelook (Skin)	Juvelook Volume
Main goal	texture, fine lines, pores, shallow scars	gradually restoring lost volume
PDLLA content	standard	higher
Depth	dermis	deep dermis to fat layer
How it changes	the skin itself gets denser	hollow areas slowly fill out

How many sessions, and when will I see results?

Phase	Typical plan
First course	about 3 sessions, roughly 4 weeks apart
When you notice it	gradually, over weeks to months
Final check	a few months after the last session
Maintenance	planned by skin condition

Some skin looks dewy right away thanks to the hyaluronic acid, but the real change follows collagen, which takes weeks to months.

As collagen fills in, shallow depressed scars and enlarged pores can gradually look less noticeable. Deep, firm scars have limits with Juvelook alone and are often planned together with other treatments.

Side effects: nodules and the under-eye area

Reaction	Usually lasts
Small raised bumps and swelling	a few days
Bruising	1–2 weeks, if it happens

The under-eye area comes up often in searches. Because the skin there is thin and nodules are more likely to be felt, Dr. Park's clinic does not inject close to it. If hollowness under the eyes is your main concern, discuss other options.

Very rarely, product entering a blood vessel can cause blood-flow problems. Every treatment carries some risk, so tell the clinic straight away if pain increases or the skin changes colour.

Tell the clinic first if you are pregnant or breastfeeding, have inflammation or a skin condition in the area, have had fillers or other skin boosters before, or tend to form keloids.

Does it hurt?

Juvelook is injected at many points, so there is a stinging feeling. Numbing cream is usually enough; for patients sensitive to pain, an injector device or sedation is an option.

Juvelook vs Sculptra and Rejuran

	Juvelook	Sculptra	Rejuran
Ingredient	PDLLA + hyaluronic acid	PLLA	PN (salmon DNA fragments)
Particles	small, uniform porous spheres	larger, irregular particles	no particles
Main use	collagen for texture, firmness, soft volume	volume restoration	skin recovery, texture, fine lines

Juvelook and Sculptra are both collagen stimulators, but they use different polymers and particles; PDLLA particles are smaller and more uniform. Rejuran works on skin recovery rather than collagen volume.

How much does Juvelook cost in Korea?

Prices differ between clinics because conditions differ. Compare on the same basis:

How many cc are used
Juvelook or Juvelook Volume
Whether a sealed, genuine product is opened in front of you
Full face or a smaller area
Whether numbing is included

Under the same conditions, prices are usually similar, so how well the clinic plans the product, depth and amount for you matters more. Current package prices with English support are on the DR.BAQUO packages page.

FAQ

Will I see results right away?

Skin may look dewy at first from the hyaluronic acid, but the main change comes as collagen forms over weeks to months.

Does it add volume like a filler?

No. Juvelook stimulates collagen so the area fills out gradually; it does not add volume immediately like a hyaluronic acid filler.

Are results permanent?

No. Skin keeps ageing, so many people continue with maintenance based on their skin after the first course.
