Would it hurt pulling off thread from my face attached by clear nail polish?

I saw a girl on youtube do this cool tutorial of "sewing" your mouth closed but she just attached the thread around her lips with eye lash glue. I wanted to try it but I dont have lash glue and ive heard of some girls who use clear nail polish to put on fake lip piercings. But I wanted to know if it would hurt to pull the string off afterwords or if I would just have to use nail polish remover and a Q-tip
