HiloWave®

HiloWave® 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

HiloWave® is an injectable hyaluronic-acid-based treatment intended to improve skin hydration and skin quality, using a dual-HA formulation designed to combine moisture retention with support for firmness and subtle fullness. It is not a substitute for surgical lifting, and it is not a conventional volumising filler for cases where substantial structural correction is required. 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 HiloWave®?

HiloWave® is a hyaluronic-acid injectable placed into selected areas of the skin to support hydration and overall skin condition rather than to reshape the face.

• The formulation features both high- and low-molecular-weight hyaluronic acid.

• It is delivered by injection using sterile, single-use syringes and needles, or an appropriate cannula.

• The stated targets are hydration, smoothness, radiance, elasticity and the appearance of fine lines.

• Subtle fullness may occur, depending on the formulation and the area treated.

• A practical planning estimate is approximately 15–30 minutes for the procedure itself, excluding consultation, preparation and numbing.

The dual-weight design is the detail that explains the stated purpose. A formulation carrying both molecular weights is aimed at two things at once — moisture retention and a degree of support — rather than at the single job a volumising filler is built for. That is a description of intent, not a performance claim, and the difference matters when a patient is choosing between the two. A patient whose concern is descent rather than dryness will be disappointed by an excellent result here, for reasons that have nothing to do with how the treatment was performed.

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.

Who Performs HiloWave® at Le.J Plastic Surgery

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

HiloWave® 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 HiloWave®?

Suitable candidates:

• Adults with suitable skin and realistic expectations who want improved hydration, radiance, texture or mild fine-line improvement.

• Patients seeking subtle skin-quality enhancement rather than dramatic facial reshaping, after medical assessment.

• Patients who want rejuvenation that does not significantly change their natural facial features.

Who should avoid or postpone:

• People with a known allergy or contraindication to the product's ingredients.

• Patients with active infection or inflammation at the proposed injection site.

• Patients with any other condition listed as a contraindication in the official product instructions.

• Pregnancy, breastfeeding, bleeding disorders, immunological conditions and anticoagulant use all require individualized medical assessment, because suitability and evidence vary.

The consultation exists to settle those questions rather than to confirm a decision already made. The clinician reviews goals, medical history, allergies, medications, previous fillers or skin boosters, skin condition and any history of adverse reactions, examines the proposed treatment area, assesses whether injection is appropriate at all, discusses alternatives and risks, obtains informed consent, and documents baseline photographs where the patient consents.

Patients enquiring from the United States tend to arrive with a product name already chosen, when the concern is what the assessment actually needs to start from. 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

At consultation the clinician reviews goals, history, medications, previous injectable treatments and skin condition, and determines whether treatment is appropriate.

On the day, the treatment area is cleansed and prepared; topical numbing or another suitable pain-control method is applied if needed; injection sites and technique are selected according to anatomy and the official product instructions; the product is administered with sterile single-use equipment; and the treated area is checked before aftercare instructions are given.

Stage	What the clinic states
Session length	Approximately 15–30 minutes for the procedure itself, excluding consultation, preparation and numbing
Total appointment	Longer than the procedure time alone
Anaesthesia	Topical anesthetic may be used; some patients tolerate treatment without numbing
During treatment	Mild to moderate pinching, stinging or pressure, varying by person and area
Immediate effects	Redness, swelling, bruising, tenderness or visible injection marks, which can persist several days or longer
Return to activity	Many patients resume routine activities the same day or the following day
When results appear	Hydration or subtle fullness may be noticeable early; skin-quality change develops over the following weeks
Course	Number of sessions and intervals are set by the clinician according to the product instructions, goals and response

Aftercare: avoid rubbing or massaging treated areas unless specifically directed, and temporarily avoid strenuous exercise, excessive heat, saunas and irritating exfoliating treatments according to the clinician's protocol. Use gentle skincare and sunscreen. Seek urgent medical attention for severe or increasing pain, pale or mottled skin, unusual discoloration, or any visual symptoms.

For an international patient there is no universal minimum stay. Allow time for consultation, treatment and any recommended follow-up; planning for one to three days may be practical for a straightforward appointment, but the appropriate stay depends on the clinic's schedule, individual recovery and travel arrangements, and it should be confirmed directly with the clinic. Many patients can travel after a straightforward hydration-focused injectable treatment once they feel well and the treating clinician has no concerns. If something feels wrong after returning home, patients can reach the clinic's English-speaking counselling manager by phone or email.

Combining HiloWave® 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.

• A structured skincare plan — the clinic may consider treatment alongside one, depending on clinical assessment.

• Selected aesthetic procedures — lasers, peels and energy-based treatments, where assessment supports it.

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.

The order and spacing of injectables, lasers, peels and energy-based procedures must be determined by the treating clinician. That sequencing decision carries more weight here than the shortlist does: each item on it places some demand on the skin, and what separates a workable plan from an uncomfortable fortnight is usually the interval rather than the selection. The alternatives the clinic names include topical moisturisers and retinoids for appropriate indications, other hyaluronic acid skin boosters, conventional hyaluronic acid dermal fillers for targeted volume correction, and selected energy-based treatments for laxity or texture. Selection depends on the primary concern, the risk profile, and the evidence behind each option.

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, so none is described here in its place. What it does state is that the exact product formulation, the injection equipment and the permitted technique must follow the official product instructions and local requirements — a boundary on practice rather than a claim about outcome.

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.

Nonsurgical does not mean consequence-free, and that too is a statement about the category rather than about this clinic: the American Society of Plastic Surgeons notes that there is still a recovery process post-procedure, typically not as intense, long or in-depth as after traditional surgery.

The Bottom Line

• HiloWave® is an injectable hyaluronic-acid treatment using both high- and low-molecular-weight HA.

• The stated targets are hydration, smoothness, radiance, elasticity and the appearance of fine lines.

• It is explicitly not a substitute for surgical lifting, and not a conventional volumising filler for structural correction.

• A practical planning estimate is approximately 15–30 minutes for the procedure itself; total appointment time is longer.

• Hydration or subtle fullness may show early, with skin-quality change developing over the following weeks.

• The clinic publishes no protocol details, no approved claims of its own, no outcome figures and no price for this service, and none are supplied here.

Frequently Asked Questions

Which material does this treatment use? A hyaluronic-acid-based formulation containing both high- and low-molecular-weight HA. It is a manufactured product, which is why the allergy and medical-history review before treatment is not a formality: a known allergy or contraindication to the ingredients is a stated reason the treatment may be unsuitable.

Will this lift my face? No, and the clinic says so directly. It is intended for hydration and skin quality, with subtle fullness possible depending on the formulation and area. It is not a substitute for surgical lifting and not a conventional volumising filler where substantial structural correction is required — if that is the concern, it is the wrong starting point.

How long does it take, and how many sessions will I need? A practical planning estimate is approximately 15–30 minutes for the procedure itself, excluding consultation, preparation and numbing, with the total appointment longer. The number of sessions and the interval between them should be set by the clinician according to the product instructions, your treatment goals and your response.

Does it hurt, and what numbing is used? Mild to moderate discomfort — pinching, stinging or pressure — is common during injections, and sensitivity varies by person and area. Topical anesthetic may be used, though some patients tolerate the treatment without numbing. A painless treatment is not promised, and temporary redness, tenderness or swelling may follow.

When will I see the result, and when is it final? Hydration or subtle fullness may be noticeable early, while improvements in overall skin quality can develop over the following weeks. The result should be assessed once the injection-related swelling and redness have settled; the clinician recommends an appropriate assessment interval, and a specific final-result date cannot be guaranteed.

How long should I stay in Korea, and when can I fly home? There is no universal minimum stay. Allow time for consultation, treatment and any recommended follow-up — one to three days may be practical for a straightforward appointment, depending on the clinic's schedule, your recovery and your travel arrangements. Most patients can travel once they feel well and the clinician has no concerns; confirm the timing if swelling, bruising or other symptoms develop.

Who should not have this treatment? Anyone with a known allergy or contraindication to the ingredients, with active infection or inflammation at the injection site, or with a condition listed as a contraindication in the official instructions. Pregnancy, breastfeeding, bleeding disorders, immunological conditions and anticoagulant use all require individualized assessment.

How do I prepare, and what should I avoid beforehand? Attend a medical consultation, disclose all medications and supplements, report previous injectable treatments and allergies, and do not have treatment over active skin infections, irritation or inflamed areas. Follow your clinician's advice on alcohol, strenuous exercise and skincare products, and tell the clinic about recent dental work, cosmetic procedures or illness. Do not stop prescribed anticoagulants or other medication without approval from the prescribing clinician.
