If you watch a few asian beauty tutorials, it's not uncommon for them to use a tape for the cheeks and heavily contour to lengthen the facial lines.

Exercise the muscles in your face on the daily. There are exercises specifically for facial muscles you can do

I agree with Kaitlyn. I've seen videos of Asain women with O faces go to 0. They look completely different though, and some people refer to them as catfishes because of how different they look, so might deal with negative backlash.

A lot of things can go into play here. If you’re young, you might still be in your baby face phase. And it’ll go away naturally eventually. If you’re trying to lose weight in your face. Exercising your whole body will help do that. But it might also just be your bone structure and you can’t change that. But look at Selena Gomez. She has an O face and is beautiful ❤️

You can't change your bones 🤷
