Source-backed answers on skin treatments, lifting, and injectables in South Korea, written for international patients. Every page starts with a short answer and states where each claim comes from.
International patients come to South Korea for skin treatment because it is safe and reasonably priced.
In 2025, 1.31 million of them were treated at South Korean dermatology clinics — 62.9% of all foreign patients, and the fastest-growing specialty.
Ministry of Health and Welfare, 24 April 2026. Foreign patients totalled 2.01 million, the first year above two million.
The treatments international patients most often seek in South Korea.
Also: botulinum toxin, 보톡스, wrinkle injection
Botulinum toxin injections relax targeted muscles and are used for expression lines, jaw slimming, and other indications. South Korea has several domestic toxin brands alongside imported ones.
In South Korea: Botulax (보툴렉스), Nabota (나보타), Meditoxin (메디톡신), Hugel Letybo
Also: 필링, 케미컬 필링, 화학박피
A controlled chemical injury that removes the outer layers of skin. Used for pigmentation, texture and acne. Depth, not brand, decides both the result and the risk — and in skin that pigments easily the shallow end is where the evidence sits.
In South Korea: 아쿠아필, 글리콜산 필링, LHA 필링, 제스너 필링
Gradual improvement over a course, with maintenance topicals doing much of the long-term work. Melasma in particular recurs without them.
Also: 필러, hyaluronic acid filler, HA filler
An injectable gel, most often hyaluronic acid, placed under the skin to restore or add volume and soften contours. In South Korea it is regulated as a medical device rather than a drug, and hyaluronic acid versions can be dissolved with hyaluronidase if something goes wrong.
In South Korea: Restylane (레스틸렌), Juvéderm (쥬비덤), Neuramis (뉴라미스), YVOIRE (이브아르), The Chaeum (더채움)
Adds volume where it is placed and softens a contour; it does not tighten skin or change skin quality, and it is temporary.
Also: 엑소좀, exosomes, extracellular vesicles
Extracellular vesicles applied to or injected into skin, marketed for elasticity, wrinkles, hydration and pigmentation. The published human evidence is early, and in South Korea the regulatory category of a given product — drug or cosmetic — is the question that matters most.
In South Korea: 엑소좀 스킨부스터, exosome after-care solution
Reported improvements are modest and the studies are small. Ask which regulatory category the product falls under before anything else.
Also: 윤곽주사, 지방분해주사, injection lipolysis
Injections intended to break down small pockets of fat, most often under the chin. Only two products are licensed in South Korea for submental fat, both deoxycholic acid — while much of what is sold as 윤곽주사 is an off-label compounded mixture with no fixed formula.
In South Korea: 브이올렛 (V-Olive), 벨라콜린 (Bellakolin), 윤곽주사
A modest reduction in a small, defined fat pocket over several sessions. Not a substitute for weight loss or liposuction, and the licensed and unlicensed versions are not the same product.
Also: 프락셀, 프락셔널 레이저, fractional CO2
Laser energy delivered in columns rather than across the whole surface, so untreated skin between them speeds healing. Ablative versions remove tissue in those columns; non-ablative versions heat without removing it, and the pooled evidence does not separate them on results.
In South Korea: 프락셀, 아그네스, 코어톡스 프락셔널, CO2 프락셔널
Meaningful improvement in atrophic scars and texture over a course, with the choice between ablative and non-ablative changing downtime more than outcome.
Also: 인모드, InMode FX, InMode Forma
InMode is a family of radiofrequency devices (Forma, FX, Morpheus8 and others) used in Korean clinics for tightening, fat reduction on the face, and RF microneedling.
In South Korea: InMode Forma, InMode FX, Morpheus8
Also: 쥬베룩, PDLLA skin booster, Juvelook Volume
Juvelook is a Korean injectable skin booster combining poly-D,L-lactic acid (PDLLA) with hyaluronic acid, marketed for collagen stimulation and skin texture.
In South Korea: Juvelook (쥬베룩), Juvelook Volume, Lenisna (레니스나)
Also: 레이저토닝, 듀얼토닝, low-fluence Q-switched Nd:YAG
Repeated low-energy laser passes over an area, most often with a Q-switched Nd:YAG at 1064 nm, used for melasma and general pigmentation. A technique rather than a device — the same name is sold on several laser platforms.
In South Korea: 레이저토닝, 듀얼토닝, 피코토닝, 제네시스토닝
Gradual lightening over a course, with melasma managed rather than cured and recurrence expected without maintenance.
Also: picosecond laser, 피코레이저, PicoSure
Pico (picosecond) lasers deliver very short pulses and are used in South Korea mainly for pigmentation, melasma toning, and some acne scar and pore treatments.
In South Korea: PicoSure, PicoWay, Discovery Pico, Pico Plus
Also: 포텐자, RF microneedling (Potenza), radiofrequency microneedling
Potenza is a radiofrequency microneedling device made in South Korea, used for skin texture, pores, acne scars, and mild tightening.
In South Korea: Potenza (포텐자), Sylfirm X (실펌엑스), Secret RF
Also: 레디어스, 래디어스, CaHA
Calcium hydroxylapatite microspheres in a gel carrier, injected for contour and increasingly diluted and spread for skin quality. It fills immediately and stimulates collagen afterwards — and unlike hyaluronic acid filler, it cannot be dissolved.
In South Korea: 레디어스, 하이퍼다일루트 레디어스
Immediate correction plus a slower collagen response. Longer-lasting than hyaluronic acid, with the trade-off that a poor result has to be waited out.
Also: Rejuran Healer, 리쥬란, PN injection
Rejuran is a Korean brand of injectable skin treatment based on polynucleotides (PN) derived from salmon DNA, used in Korean clinics for skin quality rather than volume.
In South Korea: Rejuran Healer, Rejuran HB, Rejuran I (eye), Rejuran S (scar)
Also: 스컬트라, PLLA, poly-L-lactic acid
An injectable poly-L-lactic acid suspension that provokes collagen formation over months rather than filling space. Long-lasting where it works, not reversible, and the published nodule rates vary widely between studies.
In South Korea: 스컬트라, 쥬베룩 볼륨
Gradual volume over three to six months across a course, sustained for a year or more. Nodules are the complication to understand before agreeing.
Also: skinbooster, 스킨부스터, hyaluronic acid skin booster
Skin booster is an umbrella term for superficial injectable treatments, most often hyaluronic acid based, intended to hydrate and improve skin quality rather than add volume.
In South Korea: Restylane Skinboosters, Profhilo, Rejuran, Juvelook, 물광주사 (HA)
Also: Thermage, 써마지, 써마지 FLX
Thermage FLX is a monopolar radiofrequency device used for skin tightening on the face, eyes, and body. In South Korea it is commonly compared with Ultherapy for lifting.
In South Korea: Oligio (올리지오), Density (덴서티), Volnewmer (볼뉴머)
Also: 실리프팅, barbed suture lift, PDO thread lift
Absorbable threads with barbs are passed under the skin and drawn upwards, so the barbs catch and hold sagging tissue in a new position. The thread dissolves over months; the lift it produces is modest and temporary.
In South Korea: Silhouette Soft (실루엣소프트), Mint Lift (민트리프팅), Ultra V Lift, Blue Rose Forte
A modest, temporary repositioning of sagging tissue. Published follow-up shows a large part of the initial correction is gone within a few years, and reviewers do not treat it as a substitute for surgery.
Also: Ulthera, 울쎄라, micro-focused ultrasound
Ultherapy is a micro-focused ultrasound device used for non-surgical lifting and tightening of the face and neck. It is one of the most requested lifting treatments in Korean clinics.
In South Korea: Shurink (슈링크), Ultraformer (울트라포머), Doublo (더블로), Liftera
Start from the problem rather than the product.
Same criteria, side by side, no universal winner.
Both are injected to change skin quality rather than to add contour, and both work through your own tissue response rather than by filling space. Rejuran's active is polynucleotide, purified from salmon; Juvelook's is poly-D,L-lactic acid, a collagen stimulator. The differences that matter to a patient are reversibility and the state of the evidence, and they do not point the same way.
Neither is better in the abstract; they heat different things in different ways. Thermage is monopolar radiofrequency, spreading heat through a large volume of tissue up to around 20 mm deep. Ultherapy is microfocused ultrasound, delivered at set depths, the deepest reaching the SMAS — the layer a surgeon pulls on. Both tighten skin that is still in place, and neither repositions tissue that has descended.
Every page opens with a two-to-four sentence answer to one clearly stated question, then the facts behind it.
Medical, price, and safety claims carry a source. Regulators and peer-reviewed research outrank marketing.
Pages about procedures are published only after a named reviewer with a stated credential has read them.
Aesthetics Korea is not a clinic and does not arrange treatment. Read the methodology and advertising policy.
Where South Korea publishes a rule, a register, a device approval, or a price, this site cites the ministry, agency, or statute that published it — and links the document, so you can check it yourself rather than take our word for it.
Official Resources →Pages are reviewed when their sources change and at least once a year.
Botulinum toxin blocks the nerve signal that tells a muscle to contract, so the line that muscle was folding softens. It works on lines you make by moving, not on volume loss and not on skin quality. South Korea licenses it as a drug rather than a device, and because it is a biological product every manufacturing batch must be released by the government before it can be sold.
Peels do work for melasma as a single treatment in darker skin, and the agent everyone assumes is weakest came out ahead: pooled across 478 patients, glycolic acid beat trichloroacetic acid on the melasma severity index. The more important finding is what happens afterwards — the same literature treats maintenance topicals as part of the treatment, and one study saw 70% recurrence within twelve weeks of stopping.
Dermal filler is a gel injected under the skin to add volume where it is placed — filling a hollow, restoring a contour, or softening a fold. Most filler used in South Korea is hyaluronic acid, which the body breaks down over months and which a doctor can dissolve on purpose with an enzyme called hyaluronidase. It adds volume; it does not tighten skin, resurface it, or relax a muscle.
Exosomes are extracellular vesicles applied to or injected into skin, and the published human evidence is early but consistently positive on elasticity, wrinkles, hydration and pigmentation. In South Korea there is a prior question that matters more than efficacy: many exosome products are registered as cosmetics rather than drugs, and the health ministry's stated position is that injecting a non-drug product into the body is contrary to medical law.
There are two very different things sold under this name. Deoxycholic acid licensed for submental fat has real randomised evidence — though every trial behind it was industry-funded. The compounded "cocktail" injections sold far more widely have no fixed formula, and South Korea's own health technology agency reviewed 38 studies and could not confirm a long-term effect. Only two products are licensed here for submental fat.
Fractional lasers deliver energy in columns, leaving untreated skin between them to speed healing. The pooled evidence does not support the assumption that the more aggressive option works better: a meta-analysis of eight studies found no significant difference between fractional CO2 and non-CO2 lasers on clinician assessment, patient assessment, or the incidence of post-inflammatory hyperpigmentation. What separates them is recovery time and pain.
