I have literally never had needling make a scar bigger, and I've done a lot of needling. perhaps others have, I don't know, but I haven't. I normally stamp the same spot 2 or 3 times. maybe even 4. rotating the stamp a bit, or stuff like that to try and get the needles into different positions. I have also normally already rolled the area before I stamp it. I'm pretty aggressive, but I am male, not sure if you are male or female. I have never had adverse side effects from needling. I HAVE had my main trouble spot sink in a bit after an aggressive stamping, but it swells back to normal by day's end. So I have become not afraid of over-needling what-so-ever. the more the merrier as far as I'm concerned.

I HAVE had scars get bigger, but it was after I started using retinol after I roll. The scars began getting smaller soon after, so I wouldn't worry about it.

Thanks for the response! I was scared about scars getting bigger because I read some posts on here about that happening to some people. Maybe it was because they rolled/stamped incorrectly, but I can't be sure.

I don't know how many times you roll. I just read on owndoc to stamp the same scar 6-8 times, so I will go with that for now.

yeah, that should be fine I would think. I think the coverage isn't quite as thorough with the roller. I don't actually count rolls, I've become sort of a freestyle roller, I just roll until I feel like, "that's good enough". trouble areas, I might hit 10 times or more, followed by stamping. my skin seems to be pretty tough though, I seem to heal pretty well. Nutrition is very important, I will add. without proper nutrition and supplements and topicals, I truly believe you are wasting time. Not that you won't see any results, but eating plenty of fresh fruits and veggies and taking supplements will speed the process along BIGTIME. and if scars appear to get bigger, it's because they are working to the surface. keep rolling and they will begin shrinking again. HAVE FAITH. the process is slow, it takes 5-6 months to see good results, and likely a year or two to start to become satisfied with it, but if you do nothing, you will never see results, and the other treatments out there come with serious risk. Needling appears to be the safest thing to me. just make sure not to drag or scrape the needles across your face, and always pick up the roller and put it back down before starting another roll. DO NOT leave the roller on your face and simply change the direction. And you will be just fine. also, if you're a smoker, give it up. not that you are one, but try to avoid toxins because they inevitably find their way to the skin, and they cause damage. it slows things down a whole, whole lot.

Thank you very much for the advice! It's very helpful. I will make sure to eat better. And I don't smoke.

Also for other readers interested in needling maybe you should read this, a great thread where lamarr gives needling advice including stuff about topicals and LED lights:
