I'm sure this has been asked before, and I'm pretty sure that I've read somewhere how to fix this, but I can't seem to find it now.

I've working on a original texture for a character of mine. The texture is a white clown face inspired by Rhiannon's Chantal character. The problem that I'm having is though is that when I go to render I'm getting stripes on her chin anf forehead. Any suggestions??
