Cosmetic filler injection micro cannula MIN-1850

injectionhuman

Overview
Micro-cannulas and fine needles from the HWTAI MIN series are designed for controlled filler delivery and collagen induction in facial aesthetic procedures. Available in blunt (micro-cannula) and sharp needle configurations, the range covers gauges 18G–27G and lengths 38–70 mm to suit different injection techniques and anatomical targets.

Micro-cannulas and blunt cannulas
Blunt micro-cannulas feature a non-sharp tip with lateral ports for even product distribution. Their atraumatic design displaces vessels rather than piercing them, reducing the risk of vascular injury and intra-arterial injection compared with conventional sharp needles.

Product features

• Accuracy: Precise filler placement across facial subunits to achieve targeted augmentation.
• Safety: Blunt tips lower the incidence of intra-arterial injection and vessel trauma.
• Comfort: Larger facial areas can be treated via fewer entry points, reducing patient discomfort.
• Efficiency: Procedures with micro-cannulas are typically faster due to fewer punctures and streamlined injection paths.
• Recovery: Reduced edema and bruising lead to shorter social downtime for patients.
• Versatility: Access to nasolabial fold, cheeks, lips, temples and mandibular area with controlled product distribution.

Usage, hygiene and at-home considerations
Intended primarily for professional aesthetic use: micro-cannulas are recommended for filler placement while sharp needles may be used for procedures requiring precise puncture. Strict aseptic technique is essential: cleanse and prepare skin, use sterile devices, and follow manufacturer instructions. For at-home dermaroller-type micro-needling, select appropriate needle lengths, maintain device hygiene, and avoid aggressive technique to minimize complications.
