How could i widen my lips

IMG_4289.webp
As you can see my lips are incredibly narrow, when i use mouth stretching methods like a card for example, the results last for maybe thirty minutes before reversing. Ive heard of lip cutting and i am considering it but i want genuinely wider lips not just like extended corners without any actual lip. My palate is also 42mm so not really too narrow, i am considering getting an expander for nasal breathing reasons, would that help with lips too?
