Weird Protrusions in Object

This is my object. It’s supposed to have a smooth, round look (like a head) but instead I have these weird folds in it. They are all over the head. I feel like I’ve tried almost everything and I can’t seem to make them disappear without dissolving the vertices, which deforms the object :frowning: Any ideas?

from looking at the picture, it seems that you have disconnected vertices in those areas. Duplicates.

It could be you sent the wrong file. I noticed this in the file you sent.

Yes, there were at least 20 disconnected vertices there.
