An intradermal injection is a medical procedure that involves administering a small amount of medication or substance into the dermal layer of the skin. This research focused on identifying the most suitable injection needle for precise intradermal administration of skin boosters.
The study involved conducting intradermal injections on four cadavers and participants using a 2 mm length, 34-gauge needle (N-Finders, Inc., South Korea). During the cadaveric study, the polynucleotide prefilled syringe was dyed green, and an anatomist performed dissections, removing only the skin layer. Ultrasonographic observations were carried out to ensure accurate intradermal injection placement.
In all four cadavers, the facial injections at the anterior cheek region were precisely administered intradermally at a 30-degree injection angle. However, the 90-degree injection was found just below the dermal layer upon skin layer removal.
The findings suggest that using a 2 mm needle length allows for easy and convenient intradermal injections.
皮内注射是一种医疗程序，涉及将少量药物或物质注入皮肤的真皮层。本研究专注于确定最适合的注射针，以实现皮肤增强剂的精确皮内给药。
本研究使用 2 毫米长、34 号针（N-Finders，Inc.，韩国）对四名尸体和参与者进行皮内注射。在尸体研究中，多核苷酸预装注射器被染成绿色，解剖学家进行解剖，仅去除皮肤层。进行超声观察以确保准确的皮内注射位置。
在所有四名尸体中，在前侧脸颊区域的面部注射以 30 度的注射角度精确地进行皮内注射。然而，在去除皮肤层后，发现 90 度注射仅位于真皮层下方。
研究结果表明，使用 2 毫米长的针可方便地进行皮内注射。
