Product Overview
LINEBODY is a South Korean cross-linked hyaluronic acid (HA) body filler product family marketed by STUNMEDICAL. Developed for professional body contouring and soft-tissue volume augmentation, LINEBODY contains non-animal-origin hyaluronic acid at a reported concentration of 20 mg/mL. The product family includes Soft and Hard gel formulations, with commercial presentations identified in 10 mL, 50 mL, 55 mL, and 100 mL sizes.
Unlike conventional facial dermal fillers supplied in small-volume syringes, LINEBODY includes larger-volume presentations intended for body-contouring applications. The cross-linked HA gel is designed to provide temporary physical volume and structural support within soft tissue, subject to the approved indications and regulatory status of the specific product.
LINEBODY Soft and Hard formulations are differentiated by their manufacturer-described gel characteristics. Soft Type is positioned for smoother contour transitions and relatively flexible volume correction, while Hard Type is positioned for applications requiring greater structural support.
This product page brings together the documented LINEBODY presentations for professional buyers comparing HA composition, gel type, container volume, packaging, and formulation characteristics. Exact product specifications must be verified against the supplied manufacturer's labeling.

Composition & Specifications
LINEBODY is based on cross-linked hyaluronic acid of non-animal origin. STUNMEDICAL identifies its HA concentration as 20 mg/mL and describes the product as a sterile gel intended for body-contouring applications.
Published commercial specifications further describe LINEBODY as a monophasic gel. Some distributors identify BDDE as the cross-linking agent and report residual BDDE levels below 0.2 ppm. These additional quantitative specifications require confirmation from manufacturer-issued documentation for the specific supplied product.

Cross-Linked Hyaluronic Acid
Hyaluronic acid is a naturally occurring glycosaminoglycan found in the extracellular matrix of connective tissues. Its hydrophilic molecular structure allows it to bind water and contribute to tissue hydration and viscoelasticity.
In dermal and body fillers, hyaluronic acid is chemically cross-linked to form a more stable gel network. Cross-linking modifies the material's physical properties and helps it resist rapid degradation after implantation.
LINEBODY uses cross-linked HA to provide temporary physical volume. The performance of an individual formulation depends on multiple characteristics, including cross-link density, gel cohesivity, elasticity, viscosity, and tissue interactions.
Soft and Hard Formulation Characteristics
STUNMEDICAL identifies two LINEBODY gel categories: Soft and Hard. These names distinguish the product's intended material characteristics rather than different principal active ingredients.
Soft Type is marketed for applications where a more flexible gel profile and smoother contour transitions are preferred. Hard Type is marketed for applications requiring relatively greater firmness and structural support.
However, numerical rheological measurements such as storage modulus (G'), complex viscosity, cohesivity, and cross-linking density have not been consistently established in the publicly available manufacturer documentation.
The Soft and Hard designations should not be interpreted as verified numerical rankings of firmness, elasticity, or lifting capacity. Product-specific rheological data and official instructions for use are required for detailed clinical comparison.
How LINEBODY Hyaluronic Acid Filler Works
LINEBODY uses cross-linked hyaluronic acid as a temporary soft-tissue filling material. Its principal mechanism is physical volume replacement rather than stimulation of fat growth or permanent tissue regeneration.
Physical Volume and Tissue Support
Cross-linked HA forms a hydrated, viscoelastic gel capable of occupying space within soft tissue. The gel's physical properties allow it to contribute temporary volume and structural support.
This mechanism provides the scientific basis for hyaluronic acid-based soft-tissue augmentation. However, the clinical suitability of a particular body area depends on the finished product's approved indications and supporting safety evidence.
Viscoelastic Gel Characteristics
Viscoelasticity describes a material's combined elastic and viscous behavior under mechanical forces. These characteristics influence how a filler responds to compression, deformation, and movement within surrounding tissue.
The LINEBODY Soft and Hard formulations are intended to provide different gel profiles. Their relative performance cannot be quantified from product names or HA concentration alone.
Biodegradation of Hyaluronic Acid
Hyaluronic acid is biodegradable and may undergo enzymatic and non-enzymatic breakdown over time. Chemical cross-linking generally increases resistance to degradation compared with unmodified HA.
The persistence of an implanted HA gel depends on its formulation, anatomical environment, and individual biological factors. A specific duration of effect for LINEBODY cannot be established solely from the general properties of cross-linked hyaluronic acid.
These mechanisms describe the established material properties of cross-linked HA. They do not establish product-specific clinical efficacy, durability, or safety for all LINEBODY variants.
Available LINEBODY Variants
LINEBODY is commercially identified in multiple container volumes and two principal gel types. The core product distinction is between Soft and Hard formulations, while the numerical product designation generally refers to the nominal container volume in milliliters.
The following table includes documented commercial presentations. Some package sizes are reported differently by distributors, and their equivalence has not been established through a complete manufacturer-issued SKU catalog.
| Product | Volume | Gel Type | Commercial Presentation |
|---|---|---|---|
| LINEBODY 10 Soft Type | 10 mL | Soft | Small-Volume Presentation |
| LINEBODY 10 Hard Type | 10 mL | Hard | Small-Volume Presentation |
| LINEBODY 50 Soft Type | 50 mL | Soft | Large-Volume Presentation |
| LINEBODY 50 Hard Type | 50 mL | Hard | Large-Volume Presentation |
| LINEBODY 55 Soft Type | 55 mL | Soft | Large-Volume Syringe Presentation |

LINEBODY 10 Soft and Hard Types
LINEBODY 10 is commercially documented in both Soft and Hard formulations. Each presentation contains a nominal volume of 10 mL and belongs to the same cross-linked HA body filler family.
The smaller-volume presentation provides a distinct packaging option compared with the larger 50 mL and 55 mL products. Its clinical indications, material characteristics, and permitted applications must be verified using the appropriate product labeling.
LINEBODY 50 Soft Type
LINEBODY 50 Soft Type is a 50 mL cross-linked hyaluronic acid body filler marketed with a relatively flexible gel profile. The Soft designation distinguishes its intended material characteristics from the Hard formulation.
This presentation is associated with body-contouring applications where smoother volume transitions are desired. Such positioning does not establish authorization for a particular anatomical area.
LINEBODY 50 Hard Type
LINEBODY 50 Hard Type is a 50 mL body filler using cross-linked hyaluronic acid. The Hard formulation is positioned for applications requiring comparatively firmer gel characteristics and structural support.
Exact mechanical differences between LINEBODY 50 Soft and Hard have not been quantified in the available primary technical documentation.
LINEBODY 55 Soft Type
LINEBODY 55 Soft Type is commercially listed as a 55 mL pre-filled syringe presentation containing cross-linked hyaluronic acid. It is positioned within the Soft formulation category.
Published specifications identify a nominal 55 mL syringe volume. However, some commercial descriptions of this product family also use the 50 mL designation. Buyers should verify the actual fill volume on the supplied manufacturer's packaging.
LINEBODY 55 Hard Type
LINEBODY 55 Hard Type is a commercially documented 55 mL syringe presentation using the Hard gel formulation.
Its product positioning emphasizes firmer gel characteristics for structural body-contouring requirements. The clinical significance of these characteristics must be assessed using product-specific technical documentation rather than marketing terminology alone.
LINEBODY 100
LINEBODY 100 is listed by certain international distributors as a 100 mL hyaluronic acid body filler supplied in a single vial.
The available commercial listing identifies the container volume but does not conclusively establish a corresponding Soft or Hard designation, detailed formulation differences, or its equivalence to the smaller LINEBODY presentations.
LINEBODY 50 and LINEBODY 55 are both documented in international distribution channels, but available listings sometimes use inconsistent volume descriptions. The products should be treated as separately identified commercial presentations until their actual manufacturer SKU specifications are confirmed.
Packaging & Product Presentation
LINEBODY is available in multiple commercial container formats, including vials and pre-filled syringes. Packaging dimensions and selling units differ depending on the specific product presentation.
| Presentation | Nominal Volume | Documented Container | Gel Types |
|---|---|---|---|
| LINEBODY 10 | 10 mL | Vial | Soft / Hard |
| LINEBODY 50 | 50 mL | Vial or Syringe, Depending on Listing | Soft / Hard |
| LINEBODY 55 | 55 mL | Pre-Filled Syringe | Soft / Hard |
| LINEBODY 100 | 100 mL | Vial | Not Confirmed |
Published commercial information identifies one syringe per box for certain 55 mL presentations and a single 100 mL vial for the 100 mL listing. Other configurations require verification against the original product packaging.
Container volume is a commercial packaging specification and does not represent a recommended treatment quantity. Confirm whether the selected product option refers to a single container or a complete manufacturer package.
Storage & Handling
Published LINEBODY distribution information specifies storage in a tightly closed container at room temperature, protected from direct sunlight. Exact numerical storage limits should be confirmed against the manufacturer-issued labeling of the supplied product.
- Storage Environment: Store at room temperature according to the original product instructions.
- Light Protection: Protect the product from direct sunlight.
- Container Integrity: Inspect the original vial or syringe and its packaging for visible damage before use.
- Sterile Product Handling: Maintain the integrity of the original sterile packaging and follow all applicable single-use restrictions.
- Product Traceability: Confirm the formulation type, container volume, batch number, expiration date, and manufacturer identification.
Storage requirements may vary between product presentations or regulatory markets. The supplied manufacturer's instructions for use take precedence over general commercial descriptions.
Safety & Regulatory Considerations
LINEBODY is an injectable hyaluronic acid body filler that requires appropriate medical expertise, knowledge of relevant anatomy, and compliance with the approved product labeling.
Potential adverse events associated with injectable HA fillers include pain, swelling, bruising, redness, inflammation, infection, nodules, and delayed inflammatory reactions.
Serious complications may include vascular compromise, tissue ischemia, necrosis, and other injection-related injuries. Large-volume soft-tissue augmentation may also present anatomical and procedural risks that differ from conventional small-volume facial filler treatments.
The manufacturer-reported use of cross-linked HA and the presence of Soft or Hard formulation options do not establish superior safety, suitability for every anatomical area, or freedom from adverse reactions.
Applications involving the breasts, buttocks, and other large body regions require particular regulatory scrutiny. Commercial marketing of a filler for body contouring does not independently establish approval for injection into those areas.
Product-specific regulatory authorization, permitted indications, and professional-use requirements must be verified separately for each destination country.
This information is intended for professional product identification and comparison. It does not constitute treatment guidance, establish patient suitability, or authorize any particular injection procedure.
