i disagree about needing to pay $$$$ to get someone else to do it. I have the pens, not the roller. all you do is stab yourself a few times until it looks like enough blood came out, and then smear hyaluronic acid on it. it isn't rocket science.
an anon on 4chan posted about using derma pen stamping to subdue those zits where you feel it forming under your skin but there isn't a head formed yet. i tried it and it worked.
technically that's only my 3rd session. so if it took 4-5 for your mom i just have to keep going. but it needs at least 2 weeks break between sessions.
but i also have scars on my hands and face i can't really get at. doing it on my hand hurts too much and i'm skittish on my face. the one for my face is .5mm and it's just so shallow it's hard to penetrate meaningfully. maybe to clarify, i don't have an electronic pen device, i have the cheapo $7 ones where it's just landing needles on the end of a handle and you press it down yourself. >>10069>>10069>c cup>no tiddy stretch marks
