Can Microneedling (Skinpen) Give You Additional Scars ?

Hi, I went for the second time to get microneedling with Skinpen and have scheduled an appointment again in 4 weeks. My concern is that I am seeing new scars on my face that were never there in the first place. Skin was normal on that area before .My question: is this temporary or I have gotten permanent additional scars while trying to fix acne scars that I had. Needless to say I feel horrible atm. My last treatment was done 4 days ago. This is the picture of before and after with the newly formed scar and I have also noticed on several places on the face that type of scar just this one on my nasolabial fold is the most prominent one and I think it was formed when she did the stamping the either treat nasolabial wrinkle or around acne scars . I am reluctant to have the same treatment again and do not know what to do to fix this now. :-(
