Mesh Issue or just the visulisation?

So is this issue an issue with mesh generation or the visualisation? I need to know if it is affecting my results or not:

It appears surfaces where the boundary layer was inflated shows a winglet like a ridge on the mesh. This can be seen on the above image on the central cylinder, top and bottom. Here is the view from the other angle:

Thanks in advance,

I should just say this is an extream example for demonstration usually the refinement is much smaller and the ‘wings’ much smaller (thickness of the layers).
