Do any of these concerns sound familiar?

  • Prominent pores that no foundation can cover
  • Concave acne scars that make you self-conscious without makeup
  • Feeling that your skin's firmness and elasticity aren't what they used to be
  • Starting to notice fine lines and dryness
  • Feeling that your skin "just looks dull"

These concerns might not be fully addressed by skincare alone.
Juvelook is a treatment that approaches the root of these problems by increasing collagen from within the skin.


What is Juvelook?

Juvelook is a next-generation skin booster from Korea. It is an injectable preparation that combines two ingredients: Poly-D-Lactic Acid (PDLLA) and non-crosslinked hyaluronic acid, which awaken your skin's own ability to produce collagen.

Instead of adding volume externally like hyaluronic acid injections, Juvelook's greatest feature is that it nurtures your skin from within. This results in a natural finish that makes it hard for others to tell you've had a procedure, and slowly brings about changes that make people around you say, "Your skin looks really good lately."

How Juvelook Transforms Skin

Ingredient 1: Poly-D-Lactic Acid (PDLLA) – The Main Player in Collagen Production

PDLLA is a plant-derived ingredient from corn, potatoes, and sugarcane. It is a material with proven safety, also used in surgical sutures.

When injected into the skin, PDLLA stimulates fibroblasts in the dermis to promote the production of collagen and elastin. Since your skin produces collagen on its own, lumps and bumps are less likely to occur, and the texture is natural to the touch. It also gradually breaks down into water and carbon dioxide over 1-2 years, which is a welcome benefit for long-lasting effects.

Ingredient 2: Non-Crosslinked Hyaluronic Acid – Adding Immediate Hydration

This fine-particle hyaluronic acid diffuses after injection, providing immediate hydration and glow from directly after the procedure. While PDLLA's effects are taking hold, it keeps the skin moisturized and supports the production of collagen and elastin.

Juvelook's strength lies in its ability to deliver "immediate hydration" and "future firmness" simultaneously.


Our Treatment: Manual Injection by a Doctor

At our clinic, a doctor performs Juvelook injections manually. The advantage of manual injection is the ability to target specific areas of concern.

This allows us to deliver the treatment precisely to problem areas such as pores, concave acne scars, fine lines, and under-eye areas, enabling fine adjustments that are difficult with machine injections. Furthermore, since there's no need for widespread injections, the amount injected can be kept to a minimum, reducing the risk of side effects.

After a thorough consultation to understand your concerns and desired skin condition, the doctor will propose the optimal injection plan.


Expected Benefits

① Pore Tightening

The synergistic effect of PDLLA and non-crosslinked hyaluronic acid tightens pores from within. It addresses both open and sagging pores, leading to pore-less bare skin.

② Improvement of Acne Scars and Craters

PDLLA injected into the dermis stimulates collagen production during its decomposition process, smoothing out sunken acne scars and craters. Many patients report that "long-standing scars have become less noticeable."

③ Increased Skin Firmness and Elasticity

As collagen and elastin increase, you'll feel a plump firmness to the touch. The elasticity lost with age is restored from within.

④ Improvement of Fine Lines and Dryness

Improved moisture retention and increased collagen volume lift fine wrinkles from within. High effectiveness can also be expected for those concerned about fine lines due to dryness.

⑤ Reduction of Dullness and Pigmentation

By normalizing skin cell turnover, melanin is less likely to accumulate, leading to clearer, brighter skin with improved transparency.

⑥ Improvement of Redness and Skin Roughness

Strengthened barrier function leads to skin that is more resilient to external irritants. We also receive feedback that chronic redness and skin roughness have subsided.

When will I see results? How long do they last?

Juvelook is a "cultivating treatment," so effects appear gradually. Enjoying the changes without rushing will lead to greater satisfaction.

Period Skin Changes
Immediately after treatment - 1 week Experience immediate hydration and glow from the hyaluronic acid. Redness and mild swelling subside within a few days.
2-4 weeks later PDLLA starts working on fibroblasts, and collagen production fully begins. You'll start to feel firmness.
1-3 months later Elastin also increases, and the skin becomes thicker. Fine lines begin to soften during this period.
3-6 months later (after 3 treatments) The effects peak. This is the stage where you'll most strongly feel that "my skin has changed."
After 1-2 years PDLLA slowly breaks down, and the effects continue. Maintenance every six months is recommended.

Undergoing 3-4 sessions at 1-2 month intervals will allow you to experience the effects most effectively.


3 Reasons You Can Undergo Treatment with Confidence

1. Safe, plant-derived ingredients
PDLLA is a natural ingredient derived from corn and sugarcane. It is approved by the US FDA and Korean MFDS and has a long track record of use in medical sutures.

2. No residue left in the body
Injected PDLLA naturally breaks down into water and carbon dioxide over 1-2 years. There is no concern about foreign substances remaining in the body.

3. Less likely to cause lumps or bumps
PDLLA particles are designed to be round and smooth, causing less irritation to surrounding tissues and reducing the risk of side effects such as lumps and inflammation.


Treatment Flow

  1. Consultation – The doctor will carefully examine your areas of concern and skin condition, and propose an injection plan.

Frequently Asked Questions

Q. Can I feel the effects after just one session?

Yes, you can experience the moisturizing effects of hyaluronic acid from the first session. However, for significant improvement in pores and acne scars, we recommend undergoing 3-4 sessions.

Q. Is it painful?

We use an anesthetic cream before the procedure to minimize pain as much as possible. While you might feel a pricking sensation, most people tolerate it well.

Q. How long is the downtime?

After the procedure, some redness and mild swelling may appear in the injected area for a few days, but these will subside naturally. Rarely, bruising may occur, but it will disappear within 1-2 weeks. In most cases, it can be concealed with makeup from the same day.

Q. How is it different from hyaluronic acid injections?

Hyaluronic acid injections are treatments that add volume externally. The effects appear relatively quickly but last for a shorter period. Juvelook promotes your own collagen production, so while the effects appear slowly, they last longer, for 1-2 years. It also provides a natural finish and is less likely to cause lumps.

Q. Can it be used on areas other than the face?

It can be applied to the entire face, as well as areas of concern such as the neck and back of the hands. Please consult us during your counseling session for more details.
