Dr pen M8 16 needles.
I was doing Follica style for 6 months (every 2 weeks, 0.9mm, 0 bleeding and 10min session with little erythema) without much progress. Literally felt like nothing, next day I was recovered fully.
I always healed wounds really fast, once my cat scratched my whole arm and my gf's and my wound fully healed in 4 days and hers in like 15 days (similar wound).
The only way I can bleed is >1.5MM and fairly long session with reasonable pain. I trust the science more than my broscience so thats why I was stubborn with Follica protocol but im starting to think if I dont bleed its useless for me. Literally 2 weeks after going heavier I already noticed results.
