Quick answer Chaeum, Elravie and Dermalax are Korean-manufactured hyaluronic acid filler ranges widely used in Seoul clinics. All are cross-linked HA gels available in several densities for different facial depths. They differ in cross-linking technology, particle characteristics and gel firmness rather than in fundamental mechanism, and in practice the injector's technique and product selection matter more than which brand is used.
In this guide
International patients often arrive having researched Western filler brands, then find that the clinic proposes a Korean-manufactured product they have never heard of. That substitution is not a downgrade by default. Korea has a substantial domestic filler industry, and several ranges are standard in Seoul practice. What is worth understanding is how these ranges are structured, what distinguishes one from another in clinically meaningful terms, and which questions actually predict a good outcome. This guide covers Chaeum, Elravie and Dermalax at a general level and is information rather than a treatment recommendation.
What these ranges have in common
All three are cross-linked hyaluronic acid gels. Hyaluronic acid is a polysaccharide found naturally in connective tissue; in filler form it is chemically cross-linked so that it resists rapid enzymatic breakdown and holds shape under tissue pressure.
Each range is sold as a family rather than a single product, typically spanning a soft variant for superficial placement, a medium variant for general facial volume, and a firmer variant for deep structural support over bone. The numbering or naming convention differs between manufacturers but the underlying logic is the same.
All three are also reversible in principle. Hyaluronidase can be used to dissolve HA filler, which is the main practical safety advantage of HA over permanent or semi-permanent materials, and a reason many practitioners prefer HA for a first treatment.
How cross-linking and rheology actually differ
The clinically relevant differences between HA fillers are rheological. Elastic modulus describes how firmly a gel resists deformation; cohesivity describes how strongly the gel holds together; and the degree of cross-linking influences both longevity and how the product integrates with tissue.
A high-modulus, highly cohesive gel placed deep over bone provides projection and resists flattening. The same gel placed superficially can be visible or palpable as a ridge. A low-modulus gel behaves well in fine lines but provides little structural lift.
Manufacturers describe their cross-linking technologies with proprietary names, and the marketing claims attached are frequently stronger than published comparative data supports. Independent head-to-head trials between specific Korean brands are limited, so differences described in clinic materials should be treated with appropriate caution.
Where each range tends to be positioned
Chaeum is commonly positioned around natural-feeling volume restoration, with variants used across mid-face volume and general soft tissue augmentation. Elravie is frequently presented with an emphasis on its cross-linking process and is used across a similar range of depths.
Dermalax is widely used and is often encountered in general facial augmentation, with variants spanning superficial to deep placement. In practice the clinic's choice frequently reflects supply arrangements and the injector's familiarity as much as any claimed property.
If what you are weighing is HA against a collagen-stimulating product rather than one HA brand against another, that is a more consequential decision. The differences are set out in our guide to Ellanse and Radiesse versus hyaluronic acid, and other HA ranges are compared in our guide to Neuramis and Saypha.
Factor | What it means clinically | Why it matters to you |
Elastic modulus | Gel firmness under deformation | Determines lift versus softness |
Cohesivity | How strongly the gel holds together | Affects spread and contour control |
Cross-linking degree | Resistance to enzymatic breakdown | Influences duration |
Variant within range | Soft, medium or firm | Must match depth and site |
Reversibility | HA can be dissolved | Main safety advantage of HA |
Injector technique | Plane, volume, anatomy | Largest single factor in outcome |
Risks that apply regardless of brand
Bruising, swelling, tenderness and transient asymmetry are common and generally settle within days to a couple of weeks. Lumps and visible product are usually technique-related rather than product-related and can often be addressed with hyaluronidase.
The serious risk is vascular. Intravascular injection or vascular compression can cause tissue ischaemia and, rarely, visual compromise. This risk is highest in the glabella, nose, nasolabial region and tear trough, and it depends on anatomy and technique rather than brand.
A clinic should be able to state what it keeps on hand for vascular emergency management and what its escalation protocol is. Sudden severe pain disproportionate to the procedure, blanching of the skin, or any visual disturbance during or after injection requires immediate attention rather than reassurance.
Vascular events are the risk that matters |
Severe pain out of proportion to the injection, blanching or mottling of the skin, or any change in vision during or after filler treatment requires immediate clinical attention, not observation. Ask before treatment what the clinic keeps available for vascular emergency management and who to contact out of hours. This question applies to every filler brand equally. |

Longevity and what influences it
Published durations for HA fillers generally fall in a range of months rather than years, varying with the product's cross-linking, the depth and site of placement, the volume used and individual metabolism. Mobile areas such as the lips typically show shorter duration than static areas over bone.
Marketing claims of extended longevity should be checked against the specific variant and site rather than the range as a whole. A figure quoted for a firm deep-placement variant does not transfer to a soft superficial one.
Repeat treatment intervals are therefore individual. Patients travelling internationally should factor in that a top-up requires either another trip or treatment with a different practitioner at home, which is a practical argument for discussing the maintenance plan before the first session.
Questions worth asking at consultation
Ask which specific variant within the range is proposed for each area and why that variant rather than a softer or firmer one. A practitioner who selects by anatomical requirement rather than by what is in stock will be able to answer this directly.
Ask to see the packaging and the lot number before injection, ask how much total volume is planned, and ask what the policy is if you are dissatisfied with the result or if a lump develops after you return home.
Confirm the injector's qualification as well as the clinic's. The verification steps are set out in our guides to confirming who treats you and Korean clinic credentials and hospital tiers.
How to decide between them
For most patients the brand is not the variable that determines satisfaction. Product selection within a range, injection plane, volume and the injector's anatomical judgement account for far more of the outcome than the manufacturer's name.
A reasonable approach is to decide the treatment goal first, let the practitioner propose the product class and variant, then ask them to explain the selection. If the explanation is coherent and anatomically grounded, the brand question largely resolves itself.
Where a clinic insists that a particular brand is categorically superior without reference to your anatomy or the area being treated, that is a signal about the consultation rather than about the product.
Frequently asked questions
Are Korean-made fillers lower quality than Western brands?
Not as a general proposition. Korea has an established domestic filler industry and these ranges are standard in Seoul practice. What varies between any two products, domestic or imported, is rheology and the evidence base behind specific claims, which is why the useful question is which variant suits the area rather than which country manufactured it.
Can Korean HA fillers be dissolved if I do not like the result?
Hyaluronic acid fillers can generally be dissolved with hyaluronidase, which is one of the main reasons practitioners favour HA for a first treatment. Confirm with the clinic that hyaluronidase is available on site, and ask what the arrangement is if you have returned home before deciding.
How long do these fillers last?
Published durations are usually expressed in months and vary by variant, placement depth, site mobility, volume and individual metabolism. A figure quoted for a firm deep-placement product does not apply to a soft superficial one, so ask about the specific variant proposed for your treatment.
Is it safe to have filler shortly before flying?
Swelling and bruising peak in the first days, which is uncomfortable but not usually a safety issue. The more relevant point is access: if a lump or an adverse event develops, being in another country complicates management. Leaving a few days before departure is the more conservative plan.
Should I choose the brand or let the clinic choose?
Decide the goal, then ask the practitioner to propose the product and explain the selection in terms of depth, site and tissue characteristics. A coherent anatomical rationale is a better indicator than a brand preference, whether yours or the clinic's.
