Why are there little red dots still showing in the tattoo after all other redness has went away? Fourth treatment 6 days ago.

I had a fourth removal treatment 6 days ago and I didn't have any bleeding, but did have slight bruising/ swelling. Almost all scabs have disappeared by now, but there are still little dark red dots everywhere. I feel they were much brighter red the first day, but considering this has been almost a week. Should I be worried that I still see them? The tattoo is on my ankle and had a lot of color, so I know it will take a while, but I don't think I had these issues with the other sessions.
