Technology

Cross-linking, engineered for natural results.

How hyaluronic acid is linked decides how a filler behaves — how long it lasts, how it holds shape, and how safely it is absorbed.

01 — The basics

Same molecule. Different structure.

Non-crosslinked HA spreads through the dermis and is absorbed within weeks. Cross-linking binds the chains into a cohesive gel that stays where it is placed — the basis of a dermal filler.

Planetary Motion Cross-Linking

Orbital and axial rotational forces work together to build a uniform cross-linked HA network — so less cross-linker is needed and more hyaluronic acid is preserved.

Optimized viscoelasticity lets each DéMORO formula be tailored to a different anatomical zone, keeping natural movement and longevity.

  1. A new standard

    Proprietary cross-linking innovation redefines safety and performance.

  2. Precision-crafted formulas

    Cross-linking time is finely adjusted for each product's intended effect.

  3. Minimized HA loss

    Targeted cross-linking rates reduce cross-linker use and preserve HA.

  4. Minimal cross-linker

    Only a minimal amount is required — for safe, natural, enduring effects.

Residual hyaluronic acid over time DéMORO retains more hyaluronic acid than Company A and Company B at most time points between 6 and 120 hours: 88% at 24 hours, 82% at 48 hours and 30% at 120 hours. 0%20%40%60%80%100%0hr6hr24hr48hr72hr96hr120hr144hr

Durability

More HA, retained for longer.

In degradation testing, DéMORO kept a higher share of hyaluronic acid than two comparison products through most of the 144-hour period — 82% at 48 hours and 30% at 120 hours.

  • For soft and highly cohesive gelsSafe delivery that improves precision and patient comfort.
  • Improved handlingReinforced against the pressure loss common in traditional syringes.
03 — BiViDerma

Multi Layered Crosslinking (MLC)

High-precision, multi-layered cross-linking turns HA into a high-viscosity, semi-solid gel of patented micro beads — without chemically altering the raw material.

  1. High-precision MLC

    HA is cross-linked in multiple controlled layers.

  2. High viscosity

    Density comes from structure, not from oversized particles.

  3. Semi-solid HA gel

    Ultra-fine micro beads, versatile across face and body.

  4. 100% hyaluronic acid

    Raw material and finished product are both pure HA.

Structure, not just viscosity

CONVENTIONAL MLC MICRO BEADS
Many fillers claim longevity by raising the cross-linking rate. Within technical limits, that mostly increases viscosity and particle size — which neither extends duration nor improves moldability. MLC builds a stable layered structure instead.

Performance

Hydrophilic, safe and removable.

  • Superior hydrophilic capacityA stable molecular structure delivers a stronger volume effect than other fillers of the same amount — with easy molding, even in small doses.
  • Moisture-retention testCentrifuged at 3,000 rpm for 30 minutes (1 cc sample with 500 cc of water added).
  • Safe & removableHigh cross-linking without chemical alteration of the raw material — no harm to the body as it is naturally absorbed.
