Strange edge artifacts

ninetitle

Hi I'm trying to texture a simple model made in blender but after I exported the model to substance painter and baked the normal map I found some strange arifacts around some edge:

It look fine from this distance

maybe I should add an edge loop?

I fixed an edge loop here but the result are less than stellar

some more artifacts on the upper curved edge


Thanks for the help.
