What can I do to correct small mouth and drooping lips / cheeks? 25 y/o (photos)

Hi im 25 yrs old and have a small looking mouth, droopy lips and cheeks. I think its genetic. I look so much better when i lift my cheeks up. From the corners of my mouth and the skin around my nostrils, it looks more attractive and healthier when i lift it up. Also i have a small tiny mouth, not a wide one. So by lifting it up it looks wider. Let me know what to do to reconstruct all this mess.
