smart to go slow, start with a 1.0...definitely, then once you know what you are doing move up
I use a dermastamp as my rolling scars are concentrated
I've heard mixed reviews about rolling after fillers...but with a 1.0 you are probably safe, just wait a couple weeks
clean everything, sterile skin, fresh roller and go to the owndoc.com site for great detailed directions....at 1.0 you can practice every week or 10 days...go slow and once you have it down pat move up to the 1.5
but be very careful, if you reuse the roller, please pay close attention to the directions on the owndoc site about sterilizing between uses - I use the copper peptides on their site directly after then a few hours after that I apply taz cream now .05...but my skin is very tough
good luck to you- I've been stamping for years and it definitely works, but the progress is slow but undeniable...and cheap! I've only used the roller a few times, then realized it would be so much easier to stamp, for me anyway.
