Has anyone used a dermaroller of 0.5 mm or higher? I just purchased a 0.2 mm from Ebay and it has definitely made a difference to my skin, my serums and face oils definitely absorb better and my skin feels softer.
However, to get better results and encourage collagen building I will need to use needles of at least 0.5 mm has anyone tried it and are the results worth it, also do you use numbing cream?
Thanks!
