I had lots of acnes and pimples before a time now I hardly get 2 3 pimple when the period is near. But I had lots of scars (icepick scars, tan, and black and whitehead. I consulted with Dr. before 4 months she did dermarolling with 2.5 mm needle. Now I can see on youtube people do dermarolling by own self and I wanna do that same why to waste thousands of bugs which I can do at home. My question is as I have rollers of 2.5 mm I really need anesthesia cream for skin to numb my skin totally till the treatment I can not bare that pain please suggest me the numbing cream so in do it with ease plz.
