I get microneedling with prp done a few times a year. I bought a package of 3 at my doctors office, and had my first one done last week. I've never microneedled at home, but back in September someone gifted me a Dr. Pen with 60 head replacements. Online, I saw a few doctors recommending it to their patients, as using .50/.25 sized needles just allows topicals like tret. to penetrate more, and this along with professional sessions maximizes results.
