Hi all, hope everyone's well. First time posting on here, and wanted to ask a few questions. Im about to make my first purchase soon for a Dr Pen microneedling pen, specifically for the purpose of stretch marks on my thighs as they've just recently bothered me after having them for like 8-10 years (just to at least to reduce the appearance and texture of them I know I can't completely get rid of them).

1. Would you guys recommend that I get numbing cream before doing the treatment on my thighs? I have gotten skin needling done once before on my face without numbing cream and it honestly felt the same with numbing cream. Like I was a little uncomfortable, but nothing that wasn't unbearable.

2. I was thinking of going 1.5-2mm as I did want to see some good results. Would you guys recommend this to be ok or not?

Thank you all in advance!
