I hate my downwards smile, my teeth barely show. I like my lips and the space between my lip to nose is a normal size (Photo)

What options do I have? I really don't want a lip lift, I don't want my lips to change, I don't want a obvious scar either, I'm currently going through invisalign dental treatment to straighten my teeth and to bring them more forward, I also had a previous rhinoplasty 5 years ago, I just want a big smile without it being forced, I really don't know what to do
