Salt Water Tik Tok Trend

Howdy! Has anyone seen the tik tok where someone talks about spraying salt water onto their face after cleansing and that getting rid of their acne? I wondered if it worked or if it is another tik tok gimmic 😬. I also wanted to know if spraying rice water on your face after cleansing works at all. Let me know your thoughts! Here is the tik tok btw: https://vm.tiktok.com/ZMdg9nKnD/
