Fat transfer to nasolabial folds. How long to wait before smiling or moving the lower face?

This is an interesting question. The main issue with fat transfer to the nasolabial fold is survivability. The fold itself has very little native fat so there is not a real home for the factor to live. The best place to put the fat in the fold is actually on the piriform aperture adjacent to the ala of the nose. This is the spot that fills out the depression from age. While some fat should be injected into the fold, this is not the real "money spot" for the correction you are probably seeking.

It is difficult to say without photos or an in-person evaluation. Discuss best aftercare protocol with your physician. Best, Dr. Emer
