hello Oudni2
Without the actual file it’s hard to be specific as this could have any number of causes: rendermesh needs adjusting (not likely), two surfaces are meeting tangentially or you have some naked edges. Just to name the obvious.

Your surface appears to be perfectly fine.
The “pinching” seems to be a rendermesh artifact or it might depend on your render environment.
emap zebra and curvaturecomb all show no pinch whatsoever.
