0.5mm needles. Used it last night and tonight. No bleeding because I opted for the smaller needle version, but it DOES irritate and redden your scalp. I think I'll use it every other day or every two days since my scalp was still a bit irritated when I used it tonight.
Not much of a point to this post, but I figured anyone wondering about dermarollers might like to hear what it's like to use one.
