Do you find yourself grappling with the cryptic codes of PMU (Permanent Makeup) needle cartridges? Whether you’re a novice or an experienced tattoo artist, it’s essential to have a clear understanding of these codes. Not only will it boost your professional skills, but it will also ensure the safety and satisfaction of your clients. This article, Mastering PMU Needle Cartridge Codes, we’ll unravel the mysteries of reading PMU needle cartridges codes.


What are PMU Needle Cartridges?

PMU needle cartridges are indispensable tools in the world of permanent makeup, tattooing, and microblading. They house the needles that deposit pigment into the skin, thereby creating the desired designs. Depending on the treatment, tattoo artists use different needle configurations, which are often represented by specific codes on the cartridges.


Deciphering the Codes on PMU Needle Cartridges

Reading PMU needle cartridges codes may seem daunting, but with the right knowledge and a little practice, it becomes second nature. These codes generally provide information about the needle’s configuration, diameter, taper, and even its sterility status.


Needle Configuration

The first number or set of numbers usually represents the needle configuration, i.e., how the needles are arranged in the cartridge. These arrangements can vary widely, from single needles (represented by ‘1’) to larger clusters (such as ‘3’, ‘5’, ‘7’, or more) and even specific formations like round (‘R’), flat (‘F’), or magnum (‘M’).


Needle Diameter

The following number or letter in the PMU needle cartridges code generally denotes the diameter of the needles. This aspect impacts the precision and intensity of the ink deposit. A smaller diameter allows for finer, more detailed work, while a larger one is typically used for shading or coloring.



Some PMU needle cartridges also include the needle’s taper in their codes. The taper refers to the pointiness of the needle, which affects the depth of ink deposit. A long taper, often represented by ‘LT’, will deposit ink more superficially compared to a short taper (‘ST’).



Finally, all reputable PMU needle cartridge codes will include information about the needle’s sterility. For example, the term ‘EO Gas’ indicates that the needle cartridge has been sterilized using Ethylene Oxide gas.


Importance of Reading PMU Needle Cartridges Codes

Understanding the codes on PMU needle cartridges is critical for several reasons.



Ensuring that the cartridges are sterile is paramount to avoid cross-contamination and infections.


Client Satisfaction

Different needle configurations provide different results. The correct needle choice is key to fulfilling the client’s expectations.



As a tattoo artist, your knowledge of these codes enhances your professionalism and credibility in the industry.


Decoding the complex world of PMU needle cartridges might seem like a challenge, but it’s a skill that every tattoo artist must master.
