This page has been created to help you understand which size of Dr. Pen Store cartridge is the most suitable for your skin concerns. Please keep in mind that this is a general guide only, but we hope it helps you make an informed decision about the best option for your skin. 

As a general rule, nano pins are best for increasing product absorption, 11-16 pins are best for targeted applications and 36-42 pins are best for larger and more sensitive areas (such as your neck, upper/inner thighs and underarm).

All of our cartridges - like our pens - are registered with the Australian Therapeutic Goods Register (ARTG). This means that our cartridges have been rigorously tested and adhere to strict standards around safety and quality, so you can rest assured that whichever Dr. Pen Store microneedling pen you choose and whichever cartridge size you use, you're getting the most premium-grade device available.

If you have any queries, please don't hesitate to reach out -  our in-house skincare consultant and our friendly customer service team would be happy to help!
