I believe this is was the early 2000s and in color. Not sure if it was part of a tv show series or a movie. I only remember bits and pieces.
A couple of friends stop at this trading post like shop in the woods. A girl is looking at the stuff and notice there are teeth necklaces and there are these things with cool designed on them(turns out it is tattooed human skin). There was a scene I believe where one of the friends gets taken in the back to get skinned because he has tattoos. Another friend goes to the bathroom and I think one of the stalls has no toilet ( at least I think this scene was in the show or movie). I remember there being a jar with what looks like water and little things swimming around in it that I think one of the friends are made to drink. And I believe the friend that realizes what’s going on tries to escape and starts running through the woods along the road.
