I started out derma rolling with a 1.5mm and I would roll going up and down, side to side, then diagonally, no less then 5 times each, all while holding my skin taunt. after rolling, I would spray my skin with DMSO, then MSM and gently rub that in and follow with MSM lotion. Since that didn't seem to work, I now use shea butter mixed w/vitamin e, rose hip oil, frankincense, rosewood, and lavender after spraying my DMSO and MSM spray. all have properties good for the skin
I started out rolling every 4 weeks for 3 months. When I didn't see anything change, (I know it probably wasn't right) I started rolling once a week and its been a few months. Could it be the rollers? (I did not change them as often as I now know I should have, but I always kept them clean. Both are from ebay)
Am I not using enough pressure? (I don't push down until I bleed)
Is it the products?
