The nasolabial fold on my left side is a pretty deep crevis and one syringe of juvederm is not enough to fill it(l had a treatment, but it went down considerably after three months). The left side of my face is also bigger than the right side (l don't know if this is masseter muscle related or to do with my jaw bone), which might be part of the problem. Any advice or suggestions would be so welcome. Thank you.
