How can I flatten my philtrum after direct lip lift surgery? (Photo)

Hello Doctors! About 8 months ago I got direct lip lift surgery, the incision of the lift was directly on my lip. After I did this procedure to reduce my philtrum it caused my philtrum to protrude a lot and caused my mouth to look like a gorilla when I smile. How can I fix this problem? I do not like my smile anymore and would like to flatten my philtrum.
