However, she humorously adds, "Everybody looked at me like I had three heads." Aware of the potential risks, she advises caution, "You can overdo this, you can push too hard. It’s meant to be a gentle thing you don’t do longer than 30 seconds." Hathaway reassures viewers, "Don’t stab yourself. If you’ve drawn blood you’ve gone too far. It’s not a vampire LipTok. It's just a little something to wake your upper lip up."
