Buy MICRONJET™ 30 Needles Online

MICRONJET™ 30 needles are a 30-pack of intradermal microneedle devices from NanoPass Technologies Ltd. (Israel), made from pure silicon crystal using MEMS technology. Each MICRONJET™ 600 unit uses three 0.6 mm hollow microneedles with a fixed penetration depth for controlled intradermal delivery. The short microneedle design supports a virtually painless delivery profile. Practitioners looking to buy MICRONJET™ 30 needles can source them through Medical Spa Rx.

What Sets the MICRONJET™ Needle Apart

A conventional hypodermic needle relies on the injector’s angle, pressure, and feel to reach the dermis. Skin thickness varies by site and patient, so precise dermal targeting can be difficult, which is why the Boca et al. trial compared a microneedle head-to-head with a classic needle for a protocol that requires repeated shallow placement [2].

The MICRONJET™ needle removes much of that depth variability. Each unit is a cluster of three hollow pyramid-shaped microneedles, 0.6 mm tall, mounted on a syringe like a regular needle [1]. Because the height is built into the device, dermal depth depends on the hardware rather than on operator feel. A correctly placed injection produces a visible intradermal bleb or wheal, which Levin et al. describe as the hallmark of an acceptable intradermal injection [1].

Fixed-Depth MEMS Silicon Design

MICRONJET™ uses semiconductor MEMS fabrication to define three hollow silicon microneedles on a single chip [1]. Their dimensions are established during manufacturing, giving the MICRONJET™ 600 format a fixed 0.6 mm needle height rather than relying on the injector to determine insertion depth. The silicon chip is integrated with a syringe-compatible adapter for intradermal administration [1][3].

Silicon Microneedles vs. Conventional Steel Needles

A regular needle is drawn, or ground from steel, and its wall and tip tolerances depend on the manufacturing process. The MICRONJET™ pyramids are instead defined at the wafer level, which is the same category of process used for microelectronic components [1]. This manufacturing approach supports repeatable needle geometry from device to device, reducing manufacturing-related variation in needle dimensions.

Evidence for Aesthetic Intradermal Use

The MICRONJET™ 600 is FDA-cleared for intradermal injection of any substance or drug approved for that route [3]. Product selection and suitability for the intradermal route remain the practitioner’s responsibility, and local regulatory status varies.

Skin Boosters and Biorevitalization

In a randomized split face/neck study, a hyaluronic acid-based biorevitalizing solution was injected with a NanoPass three-needle 0.6 mm silicon microneedle on one side and a 32G × 4 mm classic needle on the other. The study evaluated NanoSoft, a NanoPass three-needle, 0.6 mm silicon microneedle [2]. Both techniques improved skin quality, but the microneedle side outperformed the classic needle on several measures over the 120-day follow-up [2].

Periorbital Findings

The periorbital zone is one area where shallow, controlled placement may be particularly relevant. In the split-face/neck trial, the microneedle-treated side showed greater wrinkle improvement in the periorbital area at day 49 [2]. Because the study evaluated NanoSoft with one biorevitalizing solution, interpret the finding within that specific protocol rather than generalizing it to every MICRONJET™ under-eye treatment.

How to Interpret the Clinical Evidence

The Boca et al. trial provides relevant evidence for a NanoPass 0.6 mm three-silicon-microneedle device, but it evaluated NanoSoft rather than branded MICRONJET™ 600 [2]. The microneedle-treated side showed advantages on selected wrinkle, hydration, radiance, comfort, and tolerability measures, but the findings come from one biorevitalization protocol using one injectable. They should be treated as related aesthetic microneedle evidence rather than universal MICRONJET™ performance data. 

From Vaccine Research to Intradermal Practice

MICRONJET™ 600 was originally studied extensively as an intradermal vaccine-delivery device. Levin et al. summarize seven years of clinical experience across vaccine studies and report safe, effective intradermal administration with the device [1]. That history provides technical and clinical context for the platform, but vaccine findings should not be interpreted as evidence of aesthetic treatment efficacy.

Professional Use, Safety, and Regulatory Status

MICRONJET™ is a professional-use device for licensed practitioners in regulated healthcare settings. Each device is single-use and attaches to a standard syringe [1]. Practitioners should follow the current manufacturer instructions for use and the labeling of the product being injected.

Published tolerability findings are encouraging. In the split face/neck trial, adverse events were milder on the microneedle side, and no serious adverse events occurred over the 120-day follow-up [2]. In its 510(k) review, FDA found MICRONJET™ 600 substantially equivalent to identified predicate hypodermic devices from Terumo and BD [3].
