Obviously fake tattooing sessions

I never had a tattoo in my life, and I don't really know anyone with many tattoos. But even I know that some of those tattoos couldn't be done in just a few hours. Tattoos of those sizes and those complexities need multiple sessions to give the skin time to calm down. And could it be anymore obvious that the "reveal" is happening days later?? When a person gets a tattoo, the skin is red, inflamed, and often bleeding. Yet during these "reveals", the skin around the tattoo is in perfect shape, with no swelling, etc. It's like the tattoo version of lip-syncing. Why not show real sessions (although I think some of them are real but definitely not all)?

Also, why aren't they showing the removal of bad tattoos? Some people get their tattoos lasered off, don't they?

I just think they should show a more realistic approach to a cover-up. Show that it takes multiple sessions, multiple days, and sometimes doesn't always look very good. I mean it's clear that they are trying to show the best situations, it's just not very realistic. So what were left with is the same situation being shown over and over again.
