## Questions & Answers

**Q: How many needles are in these heads?  Does not say?  16? 36?**
A: 16

**Q: How often can i nano needle?  once a day?  three times a week?  i understand that each cartridge is for one time use.**
A: Since nanoneedling is only surface deep, you can nano as often as you'd like, within reason. Not 3 x a day, but you could nano ever day if you wanted. An Aesthetician doesn't know what nanoneedling is, let alone doing something to your own skin beyond applying skincare. I've never met a dermatologist or an aesthetician that understands what a Dr. Pen is, how it works, and that it doesn't destroy your skin once explained.

**Q: What depth setting on m8 dr. pen for nano cartridge?**
A: I watch penn.smith on YouTube,  she is a masterAesthetician and she says when you’re doing a nano needling to put it on the setting 2.0.   I hope this helps😀

**Q: Are these authentic cartridges? On Dr. Pen's website they don't carry this version, only 16 pin, 36 pin and nano...**
A: I have used these on my Dr Pen and I have had no problems, I would recommend them
