A 34G x 2.5mm (0.18mm x 2.5mm) mesotherapy needle is an ultra-fine, short hypodermic needle designed for highly superficial, precise, and minimally invasive aesthetic skin treatments. Due to their extremely small diameter, these needles are often marketed as "painless" or "mosquito" needles, significantly reducing trauma, bruising, and patient discomfort. 

Key Characteristics and Description

Gauge (34G): The 34-gauge indicates an extremely fine diameter (approx. 0.18mm), making it one of the thinnest needles available on the market, ideal for delicate areas.

Length (2.5mm): The short 2.5mm length is engineered for shallow, intradermal injections (the "meso" layer), providing maximum precision and control over depth.

Design & Quality: Often manufactured with medical-grade stainless steel (AISI 304 or similar) and designed with a specialized bevel for smooth, clean penetration.

Compatibility: Features a standard Luer or Luer-Lock connection, making them compatible with most standard, multi-injector, or mesotherapy guns.
