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.

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.



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.

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.
