NEWBIE QUESTION

Hi everyone, I’m getting ready to do my second treatment of micro needling in about four weeks. I have different concerns in different areas. On the sides of my neck I have melasma that I would like to treat and on my face mostly skin tightening in the jowl and frown line area. I have BCN hyaluron and just ordered Dermaheal SB and Dermaheal SR.

This might be a silly question, but can I use the SB on my neck and the SR on my face in the same session using the same cartridge? For reference my pen is a Dr. pen M8S and I have a variety of cartridges everything from an eight needle to a 36 needle. (Yes, They’re all brand new sealed and sterilized.)

TIA! 🙏
