10-12 minutes is plenty with something like the M8 on fastest speed. I've only got thinning in the hairline so it's even less for me.I do about 10-12 minutes. Definitely not gonna be in line with this protocol but there are others who've had success with dermarolling in a way that i am so it's worth a try at least. I doubt other studies into dermarollling did it at 1600 holes per square centimetre.
Of course, this is assuming that the specs for Dr pen devices are true.
