Can you help with deep nasolabial fold on right side of face?

Hi I'm 52 and for many years had a deep Nasolabial fold on my right side, whilst generally considered youthful looking for my age. It affects my confidence immensely, once described as if I had a stroke :-( I'm wondering if treatment could help. Thing is if I hold down the fold with my finger and move slightly towards my nose it helps massively, or puff up a touch from inside the mouth. My muscle seems to be pulling it upwards making it worse. Please can you help.
