Smoothing glitching out

Hello there, i recently made a model of a face, and it seems that there is a glich with smoothing the model. is there any way of fixing this withoud remaking the model?
here’s the model without smoothing:


and here it is with smoothing:

Go to edit mode
Select all vertices - shortcut A
Remove doubles - W / remove doubles
Recalculate face normals - Ctrl+N

yay, thanks :smiley:
