Elasty D Plus: Why PNET Technology Makes This Korean Filler Different

Written by FillersFairy Editorial · Reviewed by FillersFairy Clinical Team · Last updated: July 5, 2026

What Is PNET Technology — And Why It Matters

Every HA filler needs crosslinking to last in tissue — without it, the body degrades hyaluronic acid within days. The industry standard crosslinker is BDDE (1,4-butanediol diglycidyl ether). But BDDE has a downside: unreacted residual BDDE left in the gel can contribute to inflammatory responses and reduce biocompatibility.

Dongbang Medical’s answer is PNET — Preserved Natural Entanglement Technology. This is a 3D crosslinking process that achieves two things simultaneously:

1. Higher crosslinking efficiency. PNET optimises the reaction so that virtually all BDDE is consumed during crosslinking — leaving near-zero residual BDDE in the final gel. Industry standard permits 0.2–2 ppm residual BDDE; Elasty targets levels below detection thresholds.

2. Preserved long-chain HA. Conventional crosslinking processes break HA chains to create new bonds. PNET preserves the natural entanglement of long HA chains while adding crosslinks — maintaining the polymer’s inherent viscoelasticity rather than creating it artificially through heavy crosslinking.

The clinical result: a gel that’s elastic enough to move naturally with facial expressions, cohesive enough to maintain its shape in tissue, and biocompatible enough to minimise post-injection inflammation.

Product Specifications

The Elasty Product Line

Elasty D Plus sits in the middle of a three-tier system, each using the same PNET technology at different densities:

For clinic buyers, the full Elasty line covers everything from superficial refinement (F) through standard corrections (G Plus) to deep volumisation (D Plus) — all from one manufacturer, one technology platform and one ordering relationship. Browse Elasty products →

Clinical Applications

Elasty D Plus is designed for mid-to-deep dermal injection. The clinical applications reflect its medium-to-high density:

Injection Technique

Needle/cannula: Supplied with 27G thin-wall needles. Low, constant injection force through the syringe — PNET gel flows smoothly without the “burst through” effect of chunky gels. Cannula (25G blunt) suitable for linear threading in nasolabial folds and cheeks.

Depth: Mid-to-deep dermis for wrinkle correction. Deep subcutaneous or supraperiosteal for volumisation.

Technique options: Linear threading for folds, fanning for broader areas, serial puncture for lips, bolus for chin/cheek projection. The monophasic, cohesive gel distributes evenly regardless of technique — no granular clumping.

Overcorrection: Minimal overcorrection needed. PNET gel swells less post-injection than conventional fillers, so what you inject is closer to what the patient sees at final result.

Why Clinics Choose Elasty D Plus

PNET safety profile. Near-zero residual BDDE means reduced inflammatory potential — fewer post-injection complications, less swelling, faster settling. For practices that prioritise safety communication with patients, PNET is a differentiating talking point.

Predictable injection behaviour. Low, constant extrusion force through 27G needles. No resistance spikes, no sudden gel release. Predictable placement leads to predictable results — important for both new and experienced injectors.

Competitive wholesale positioning. Korean-manufactured HA fillers at wholesale pricing deliver margins comparable to — or better than — Western premium brands, while offering equivalent clinical performance. The Elasty line covers fine through deep indications, simplifying the procurement relationship. Check Elasty wholesale pricing →

Frequently Asked Questions

What is Elasty D Plus used for?

Moderate-to-deep wrinkle correction (nasolabial folds, marionette lines), facial contouring (cheeks, chin), lip augmentation and minor non-surgical rhinoplasty. It’s the “deep” tier in the Elasty product line — designed for mid-to-deep dermal injection.

How long does Elasty D Plus last?

8–12 months depending on treatment area, injection depth and individual metabolism. Areas with more movement (lips, perioral) tend toward 8 months; areas with less movement (cheeks, chin) tend toward 12 months.

What is PNET technology?

PNET (Preserved Natural Entanglement Technology) is Dongbang Medical’s proprietary HA crosslinking process. It preserves the natural long-chain structure of hyaluronic acid while achieving near-zero residual BDDE — resulting in a more biocompatible, elastic gel with reduced inflammatory potential.

How does Elasty compare to Juvederm or Restylane?

All three are crosslinked HA fillers used for similar indications. Elasty D Plus offers comparable clinical performance (24 mg/mL HA, monophasic, 8–12 months) at Korean wholesale pricing — typically a significant cost advantage for clinics. PNET technology provides a differentiated safety narrative (near-zero BDDE).

What needle size for Elasty D Plus?

Supplied with 27G thin-wall needles. Also compatible with 25G blunt cannulas for linear threading techniques in nasolabial folds and cheeks. The PNET gel’s smooth, cohesive texture enables low extrusion force through both needles and cannulas.
