A 30G x 8mm (0.3 x 8mm) mesotherapy needle is a high-precision, ultra-fine, and short-length needle designed for intradermal injections, skin boosters, and cosmetic procedures. The "30G" refers to a 30-gauge thickness (yellow color code), which is thin enough to minimize patient discomfort and reduce the risk of bleeding. 

Key Features & Characteristics:
