Technology

Enhanced Interlinked 3D Matrix

Free hyaluronic acid has a half-life of 24 to 48 hours in tissue. EIM™ is the process that turns those loose chains into a cohesive three-dimensional network — one that holds a shape, resists enzymatic breakdown, and still lets water, oxygen and nutrients pass through it.

The idea

Two halves, named by the brand itself

Eikonha's own brochure sets exactly two words in script. They are not decoration — they name the two halves of the proposition.

Art

The artistic approach through Golden Ratio

Eikonha treats facial aesthetics as proportion rather than volume for its own sake — the range is built to reshape architecture, not simply to fill.

Science

EIM Technology

Enhanced Interlinked 3D Matrix: the four-step process that turns free hyaluronic acid chains into a cohesive, purified, size-calibrated gel.

The process

Four steps, in order

Each step exists to fix a specific problem with the step before it.

Free HA
BDDE
Cross-linked HA

01 Cross-linking

Free hyaluronic acid chains are covalently bonded using BDDE, binding long-chain sodium hyaluronate into a single cohesive three-dimensional network rather than a loose collection of independent chains.

Step 1 of 4

The four-step EIM process. Cross-linking: free hyaluronic acid combined with BDDE produces cross-linked hyaluronic acid. Dialysis: residual BDDE is removed, leaving purified cross-linked hyaluronic acid. Sieving: the gel is calibrated to a uniform particle size. Lubrication: free hyaluronic acid is reintroduced and pH adjusted, before filling into the Eikonha syringe.

Composition

What is in the syringe

Consistent across the entire range. Particle size is the only variable that changes between products.

Composition
Non-animal, cross-linked sodium hyaluronate gel
HA concentration
20 mg/mL
Cross-linking agent
BDDE (1,4-butanediol diglycidyl ether)
Anaesthetic
Lidocaine 0.3% (where applicable)
Resorption
Fully bioresorbable
Rheology
Characterised viscoelastic profile (G′ / G″)

Measured elastic (G′) and viscous (G″) moduli are published in the product specification file for each market rather than here.

Why it matters

What the matrix actually does

Each of these is a consequence of the network structure, not a marketing adjective.

Tissue-integrated network

The coiled three-dimensional hydrophilic matrix permits diffusion of water, oxygen, nutrients and metabolites through the gel, supporting the normal physiological function of the surrounding tissue.

Sustained hydration

At 20 mg/mL, the cross-linked network presents a large hydrophilic surface area that binds and retains water for lasting, natural-looking volume.

Resistance to enzymatic degradation

Cross-linking slows enzymatic breakdown by hyaluronidase relative to uncross-linked hyaluronic acid, supporting extended in-tissue duration.

Cohesivity with controlled syringeability

The network balances gel cohesivity with smooth, controlled extrusion for predictable placement at the intended tissue plane.

Defined viscoelastic profile

A characterised elastic (G′) and viscous (G″) modulus profile provides structural support while integrating naturally with surrounding tissue.

Shape retention and reduced migration

The cohesive network helps the gel hold its placed contour and resist displacement after injection.

Safety parameters

What dialysis removes

BDDE is the cross-linking agent that makes the matrix possible — and the thing dialysis exists to take back out. These parameters are published qualitatively by Eikonha; no thresholds are stated, so none are invented here.
