So I found a way to increase the thickness of your face and want to share it with you guys. Step. 1 Hang out with a person that hates you and have a higher position than you. Step. 2 Accept all their insults. That's what I've gathered so far. I found out about this because my Art & Design teacher absolutely despises me and roasts me everyday and I can't even do anything about it. This has been happening since school started for me(3 weeks). I didn't realize that my face thickened until I tried doing something extremely embarassing twice and not feeling any shame from it That's all I got for now so good luck developing your face.
