Juvelook®

Juvelook® in Seoul at Le.J Plastic Surgery

Medically reviewed by Dr. Kim Ji Sun, M.D., M.S., Ph.D., Board-Certified Otolaryngologist · Le.J Plastic Surgery, Gangnam-gu, Seoul

Juvelook® is an injectable skin treatment that combines poly-D,L-lactic acid (PDLLA) with hyaluronic acid (HA), designed to support collagen production and improve skin hydration, texture, elasticity, and the appearance of fine lines. The two components do different work on different timescales, which is the single most useful thing to understand about it before booking. At Le.J Plastic Surgery in Gangnam-gu, Seoul it sits within the clinic's Anti-Aging & Regenerative range, and it is performed personally by Dr. Kim Ji Sun, the clinic's founder and Medical Director and the listed performing doctor for the parent Anti-Aging & Regenerative specialty.

What Is Juvelook®?

Juvelook® is the injection of a product containing PDLLA and hyaluronic acid into targeted areas of the skin, based on the individual's concerns and treatment goals.

• The formulation contains two materials: poly-D,L-lactic acid (PDLLA) and hyaluronic acid (HA).

• It is administered by injection into planned treatment areas rather than applied to the surface.

• The stated intent is to support collagen production and to improve skin hydration, texture, elasticity, and the appearance of fine lines.

• Skin improvements are described as developing gradually over several weeks to months as collagen production is stimulated.

• A session typically takes around 30–60 minutes, and maintenance sessions may be recommended.

The timescale deserves to be stated before anything else, because it is where expectations most often go wrong. A treatment described as supporting collagen production is, by definition, not a treatment that finishes its work on the day it is given. The clinic's own description places visible improvement over several weeks to months, and a patient booking a trip around an event three weeks away is planning around the wrong treatment, not around a wrong clinic.

The clinic has not published technique details specific to its own protocol, and this page does not supply any in their place. It has likewise not confirmed approved claims of its own for this treatment, so nothing beyond the stated purpose above is asserted here — not an efficacy figure, not a comparison, and not a regulatory status. What the clinic does state about equipment is modest and worth repeating as given: the treatment uses an injectable formulation containing PDLLA and hyaluronic acid, and the clinician may use sterile injection equipment, skin-cleansing supplies, and topical numbing products when appropriate.

Who Performs Juvelook® at Le.J Plastic Surgery

Dr. Kim Ji Sun, M.D., M.S., Ph.D.
Board-certified Otorhinolaryngologist

Juvelook® is performed personally by Dr. Kim Ji Sun, the clinic's founder and Medical Director and the listed performing doctor for the parent Anti-Aging & Regenerative specialty.

Dr. Kim is a board-certified otolaryngologist who earned an M.D., a Master's degree and a Ph.D. from Dankook University College of Medicine, completed internship and residency at Dankook University Hospital, trained as a Clinical Fellow in the Department of Otorhinolaryngology at Asan Medical Center, and has served as a Guest Professor at Stanford University School of Medicine in the United States.

Dr. Kim's most recent relevant academic activity is a 2026 lecture on non-surgical facial rejuvenation and closed rhinoplasty at the 12th meeting of the Korean Academy of Facial Plastic and Reconstructive Surgery, where Dr. Kim is a regular member and serves on the academic, public-relations and international committees.

Le.J Plastic Surgery is a single-doctor clinic, so the surgeon who assesses you is the surgeon who treats you.

Who Is a Good Candidate for Juvelook®?

Suitable candidates:

• Adults concerned about skin texture, fine lines, or mild volume loss, who have realistic expectations and are medically suitable for injectable treatment.

• Patients willing to have skin condition, treatment goals and medical history assessed by a qualified clinician rather than selecting a product in advance.

• Patients comfortable with improvement that develops over weeks to months and may require maintenance.

Who should avoid or postpone:

• People with an active skin infection or inflammation at the planned injection site.

• People with known ingredient allergies, or certain medical conditions.

• Patients who are pregnant or breastfeeding, or taking medicines that affect bleeding — all should be discussed with the clinician.

The candidacy question here has an unusual middle ground, and it is worth naming. This treatment is listed for skin texture, fine lines and mild volume loss, which places it between a pure skin-quality injectable and a volumising one. The practical consequence is that "mild" is doing real work in that sentence: a patient with substantial volume loss is not a marginal candidate for this treatment, but a candidate for a different one. Establishing which side of that line you fall on is the first job of the consultation, which usually runs through discussing skin concerns and treatment goals, reviewing medical history and allergies, examining the skin, assessing suitability, explaining risks and expected outcomes, and agreeing a treatment plan.

The American Academy of Dermatology recommends that before undergoing any cosmetic procedure consumers ask what the risks for the procedure are, and ask the doctor how many times they have performed the exact procedure.

What to Expect: Procedure, Recovery, and Results Timeline

The clinic describes the appointment in six steps: consultation and skin assessment; cleansing of the treatment area; preparation of the product by the clinician; injection into the planned treatment areas; assessment of the treated skin; then aftercare instructions and follow-up planning.

Stage	What the clinic states
Session length	Typically around 30–60 minutes
Anaesthesia	Not confirmed by the clinic; topical numbing products may be used when appropriate
Discomfort	Brief discomfort, stinging or pressure during injections, varying by area and individual
Early recovery	Mild redness, swelling, bruising or tenderness, improving within a few days to a week
When results appear	Gradually over several weeks to months as collagen production is stimulated
Maintenance	Maintenance sessions may be recommended

The anaesthesia line is a genuine gap rather than an omission on this page's part: the clinic records its pain-control approach for this treatment as not confirmed, while separately noting that topical numbing products may be used when appropriate. Since discomfort during injection is expected, what will be used is a reasonable thing to establish at consultation rather than on the day.

Possible side effects include temporary redness, swelling, bruising, tenderness, and small bumps at injection sites. Less common complications may include infection, allergic reactions, persistent nodules, uneven results, or inflammatory reactions. Aftercare follows the clinician's instructions for skincare and activity restrictions: avoid unnecessary pressure on treated areas, and seek medical advice if swelling worsens, pain is severe, or unusual skin changes occur.

For international patients the clinic's guidance is specific. A stay of 1–2 days in Korea may be sufficient for the appointment and initial follow-up, depending on the treatment plan, and patients may fly home within that period if they feel well and the treating clinician confirms it is appropriate. What that short stay does not cover is the result, which arrives months later and at home — so the follow-up that matters most for this treatment is the remote kind. If something feels wrong after returning home, patients can reach the clinic's English-speaking counselling manager by phone or email.

Combining Juvelook® with Other Treatments

• Other skin-quality injectables in the same range — the clinic offers further injectable options aimed at skin texture and quality, each working through a different material.

• Volumising injectables — where the concern is clear facial volume loss rather than skin condition, Radiesse addresses a different problem.

• Lasers and energy-based treatments — available at the clinic, and sometimes the better match depending on the concern.

The clinic publishes no per-procedure pages for several of these, so they are listed without links rather than linked to pages that do not exist. Combination treatments may be considered depending on the patient's goals and skin condition, and the treating physician should determine the suitability of combining Juvelook with other injectables, lasers, or energy-based treatments. The clinic has not published alternatives or comparisons of its own for this treatment, so none are ranked here; what a comparison would need, and what the clinic has not published, is outcome data for each option in the same patients.

Safety, Precision, and Clinic Standards

Le.J Plastic Surgery is a Registered Medical Institution for Attracting Foreign Patients, certified by the Ministry of Health and Welfare in compliance with the Medical Overseas Expansion and Foreign Patients Attraction Act. This is a registration for treating international patients; it is not an accreditation of any treatment in this category.

The clinic has not published a risk-reduction protocol specific to this procedure, and records the specific risks a patient should know as not confirmed. The stated side-effect list above is what the clinic does publish, and this page does not extend it by inference.

Le.J Plastic Surgery publishes neither case volumes nor complication rates for this procedure, and this page claims neither. That is a fair question at consultation, as is the one worth asking any surgeon in this category: how many of these operations they have performed, how many involved complications, and what follow-up to expect if something goes wrong.

Choosing between a nonsurgical treatment and surgery is itself a question about the category, and the American Society of Plastic Surgeons puts the difference this way: the primary difference between traditional plastic surgery and minimally invasive procedures lies in the scope of the procedures themselves and the recovery afterward.

The Bottom Line

• Juvelook® injects a formulation of PDLLA and hyaluronic acid into targeted areas of the skin.

• The stated aim is to support collagen production and improve hydration, texture, elasticity and the appearance of fine lines.

• A session typically takes around 30–60 minutes; maintenance sessions may be recommended.

• Results develop over several weeks to months, not on the day — this is not a treatment to book against a near date.

• Redness, swelling, bruising, tenderness and small injection-site bumps are the common effects; nodules, infection and inflammatory reactions are the less common ones.

• The clinic has not confirmed its anaesthesia approach, its risk-reduction protocol or approved claims of its own for this treatment, and none are supplied here.

Frequently Asked Questions

What are PDLLA and hyaluronic acid, and why both? They are the two materials in the formulation. The clinic's stated design is that the product supports collagen production while also improving skin hydration, texture and elasticity. Beyond that stated purpose, the clinic has not published a technical account of how the two components are balanced, and this page does not supply one.

When will I actually see a difference? Over several weeks to months, as collagen production is stimulated. Final results and their duration vary between patients, and maintenance sessions may be recommended. If you need a visible change by a fixed date, say so at consultation — the answer may be that a different treatment suits the deadline better.

Does it hurt, and what numbing is used? Patients may experience brief discomfort, stinging, or pressure during injections, varying by treatment area and individual sensitivity. The clinic has not confirmed a standard anaesthesia approach for this treatment, though topical numbing products may be used when appropriate — worth agreeing in advance rather than on the day.

Who should avoid or postpone it? People with an active skin infection or inflammation at the planned injection site, known ingredient allergies, or certain medical conditions. Pregnancy, breastfeeding, and medicines that affect bleeding should be discussed with the clinician before treatment.

How long should I stay in Korea? A stay of 1–2 days may be sufficient for the appointment and initial follow-up, depending on the treatment plan. You may fly home within that period if you feel well and the treating clinician confirms it is appropriate.

What are the common side effects? Temporary redness, swelling, bruising, tenderness, and small bumps at injection sites. These usually improve within a few days, although some effects may last longer. Less common complications include infection, allergic reactions, persistent nodules, uneven results, or inflammatory reactions.

How should I prepare? Tell the clinician about your medical history, allergies, medications, and previous cosmetic treatments, and follow the instructions given regarding skincare and preparation. Avoid alcohol and irritating skincare products beforehand if advised, do not stop prescribed medicines without medical advice, and follow the clinic's pre-treatment instructions.

Is this a volume treatment or a skin treatment? Mostly the second, with a stated role in mild volume loss. That middle position is why the examination decides it rather than the product name: substantial volume loss points elsewhere, and a plan that leads with this one for a clearly structural concern is worth questioning.
