Redness is mostly subsided after 12 hours. Some pinpoint bleeding. Lots of burning when adding topicals, skin sensitive to touch last night, but no pain in the morning, and scalp is just kind of numb. I think you build up a tolerance to it over time. I worked my way up to doing 30 minutes, so it would probably hurt more/longer for someone who has only lightly needled. Previous session I needled for 20 minutes, and this time 30 minutes. The first time I ever used a dermaroller for about 10 minutes I had trouble sleeping due to how sensitive my scalp was to touch. In time it got to where there was no discomfort from the moment the session was over. This 30 minute microneedling session took me back to close to how it felt that first time that I dermarolled. I wonder if you get diminishing returns with wounding as you build up tolerance to it.
