Have u used it personally? did it work for u?
I've done microneedling as well as tca peels sessions myself and I wont lie I did see textural changes and overall improvement. Granted I didn't completely remove my scars but I sure as hell improved the way they look. This is after at least 8+ session. I've also only done it for a year and full blown results are seen after 2+ years of microneedling. I now have a automated microneedling device that owndoc sells called the Derminator that targets scars more precisely and correctly. It's also more tolerable considering the speed at which the needles are inserted into the skin is sped up. (imagine pulling a hair quickly rather then slowly) I plan on using it after a session of subcision in march.
That said, most results are seen after combination of numerous treatments! I've done 10+ tca peels, 10+ microneedling sessions and 3 vbeam perfectas. I'm a bit more comfortable with my skin but I have lots more room for improvement.
