Nasolabial folds troubles (photos)

Thank You in advance for your answers. I had nasolabial injection before 3 years ago 1 ml in each fold. Hialyronic acod Revanesse ultra, and after 3 years I have already material but migrated by sides of upper lips. It is not resorpted at all. How it is possible? Is it result of bad applying or deep applay, or my methabolisam is to slow?Hyaluronidase enzim is solution, but i want to fill that area. I read that fat inj. is no too good there is possibilities of yellow pigmentation of the skin.
