Tighten up a Mesh

I created this form with Kangaroo and it’s quite close to what I wanted it to look like.

My only issue is that I’m left with a lot of these creases that you can see in the attached image.

Is there a way to get rid of the creases and ‘tighten’ the mesh up in some way without deviating from the form too much?

Thank you!
