Is subcision for my nasolabial folds safe and is it worth it? Will it improve asymmetry? (photo)

I have deep nasolabial folds. Furthermore, they are asymmetric so that my right cheek seems lower than the left. I have been offered a subcision for improving them. Is this generally safe, and can it be done so that asymmetry of the face is improved? How’s the recovery from this? I have hotten some information from my doctor but would love to hear second opinions.
