Does drinking 2-3 liters of water really help your skin or this is just a propaganda?

I was wondering if drinking this much water and risking to go to the toilet a hundred of times during the day really helps or not?

Edit: just ignore the word “propaganda “ and answer me pls.

Second edit: i feel like i used the wrong word with my bf and he is not stopping making fun of me over it, guys I USED THE WRONG WORD lol.
