For those with dense ink, when did you really start to see a change?

I know results vary by person, lifestyle, skin tone etc, but I’m curious to hear how long it took those with very dense ink to notice a difference?

I have 2 large, VERY dense tattoos on each leg (sigil font tattoos) that I have been removing. I just went in for my second session 2 days ago! I know I’m still very early in the process to see significant progress, but I’d love a good estimate of when to expect that turn around progress.

I have noticed very very slight changes, which I have been impressed by, but for the most part they still look the same.
