Greetings @MoreCoin89!
We’re SO stoked to welcome you to the Unreal Engine community! We see that this is your first post to our forums! 
Thank you for posting your issue with your Metahuman. It looks like your character has a case of Glowing Lacrimal Fluid. I’ve included a thread here that will lead you on the path to resolution. I hope this helps!
Thank you so much for being an important part of our growing community! Happy Creating and have loads of fun exploring Metahuman!
