Earlier quoted context omitted.
I think somebody watched a lot of pimple-popping videos while logged into your account. You might want to take a look at your viewing history: https://www.youtube.com/feed/history Because that's definitely not a default. I've never seen YouTube recommend one of those in my life.
I have my childrens accounts under my main account. If they watch a lot of certain types of videos, that will show up as a suggestion under my main account. I'm positive its not because they are using my account, I watch videos with them. I also have a second account for watching more technical videos and that leaks into my main account suggestions.
I turn this "feature" off every time I open it, it tells me it has saved that configuration, but that is not the case. like other poster commented, review your view history and delete anything you do not want to see or clear it out entirely. There is also option to "don't recommend channel" ([3x ...] beside the video)
