Professional Handling Guide: EPTQ S500 Hyaluronic Acid Filler

EPTQ S500, manufactured by Jetema in South Korea, is a cross-linked hyaluronic acid dermal filler. It is characterized by its high viscoelasticity, positioning it as the densest product in the EPTQ line. The '500' designation refers to the particle size, indicating its suitability for specific applications determined by the trained practitioner.

Key technical details for procurement and inventory management include:

When stocking your clinic, understanding these specifications is the first step in proper inventory control. The full Hyaluronic acid dermal filler catalog includes a range of products with varying densities, such as the softer D.Fill Soft, for comparison.

Upon receiving a shipment of EPTQ S500, the first action is to verify the packaging and its contents. Each unit box should be factory-sealed and show no signs of tampering. Professionals should conduct a systematic check to confirm product authenticity and readiness for clinical use.

Inside each box, you will find:

• One sterile, pre-filled syringe of EPTQ S500 (1.1ml).
• Two sterile 27G UTW needles, individually sealed in blister packs.
• Product traceability labels with unique lot numbers.
• An information insert for professional reference.

Inspect the syringe's sterile packaging for any breaches. Cross-reference the lot number on the box with the number on the syringe itself. This is a critical step for internal record-keeping and traceability. Any discrepancies or damage to the packaging may compromise sterility and should be reported to your distributor immediately.

Correct storage is fundamental to maintaining the integrity of hyaluronic acid fillers. EPTQ S500 must be stored within a specific temperature range of 2°C to 25°C (36°F to 77°F). Exposure to temperatures outside this range, particularly freezing or excessive heat, can irreversibly alter the molecular structure of the HA gel, affecting its rheological properties and performance.

Key Storage Protocols:

• Avoid Freezing: Never store the product in a freezer. Freezing can cause the HA gel to degrade and the syringe to fracture.
• Prevent Heat Exposure: Keep away from direct sunlight, radiators, or other heat sources within the clinic.
• Upright Storage: While not mandatory, storing boxes upright can help prevent pressure on the syringe plunger.

For clinics receiving bulk orders, confirming that your wholesale supplier maintains a strict, documented cold chain during transit is essential. This ensures the product arrives at your facility with its specified characteristics intact.

EPTQ S500 is supplied in a pre-filled syringe designed for immediate professional use. Proper preparation ensures a smooth and controlled procedure.

1. Inspect the Gel: Before attaching the needle, visually inspect the gel through the syringe barrel. It should be clear, transparent, and homogenous. The presence of air bubbles is common; they can be removed by gently tapping the syringe and carefully pushing the plunger until a small bead of gel appears at the tip.
2. Needle Attachment: Remove the cap from the syringe tip by pulling it straight off. Unpack one of the provided 27G needles. Securely attach it to the Luer-lock syringe tip with a firm twisting motion until it is snug. Do not overtighten.
3. Priming the Needle: With the needle attached and pointing upwards, slowly advance the plunger until a small drop of gel is visible at the needle tip. This confirms that the syringe and needle are patent and ready for use.

Due to its high viscosity, EPTQ S500 requires a steady, controlled injection pressure. The included UTW needles are designed to facilitate a smoother extrusion compared to standard needles of the same gauge. Some practitioners may prefer to use a cannula, which would require a separate purchase and adherence to the cannula manufacturer's instructions for use.

Standard protocol is to use EPTQ S500 as supplied by the manufacturer. However, in specific off-label circumstances, a qualified practitioner may decide to modify the filler's viscosity by dilution. This is an advanced technique performed at the professional's discretion and responsibility. The most common diluent is sterile saline solution for injection.

Dilution will alter the product's cohesivity and G' prime, making it less firm and more spreading. The precise ratio is determined by the practitioner based on their clinical judgment for a specific application. It is imperative to use a sterile mixing technique, typically involving a female-to-female Luer-lock connector, to transfer and mix the contents between two syringes to achieve a homogenous consistency.

This process is conceptually similar to the reconstitution of lyophilized powders, though the objectives differ. For further reading on handling injectables that require mixing, the professional guide to Liztox 100unit: Professional Guide to Reconstitution, Diluti provides relevant information on sterile mixing protocols.

For clinics and resellers, sourcing authentic EPTQ S500 from a reputable distributor is paramount. Wholesale pricing is typically structured in tiers, rewarding higher volume orders. For example, illustrative pricing may start at $85.00 per unit, with discounts scaling from 4% for 11+ units to 8% for 51+ units. These figures are for reference; always request a current price list.

When evaluating suppliers, inquire about their shipping procedures, cold chain verification, and policies for handling damaged goods. A reliable partner ensures you receive authentic, properly stored products, safeguarding your clinic's inventory and reputation. Exploring different product lines, from high-viscosity options like D.Fill Hard to biostimulators, allows you to build a comprehensive injectable portfolio.
