Question about dermal lip grafting vs temporalis fascia grafting for lip augmentation

Hi! I am deciding between having dermal fat grafting (where an actual strip of skin is removed and pulled through the lips) or a temporalis fascia lip graft done, and I have a question. Would a fascia graft be more resistant to absorption than a dermal fat graft? I know with fat injections, you have to worry about them dissapearing with weight loss, being absorbed by the body, etc. So is that the same case with a dermal fat graft, since there is a small amount of fat attached? Thank you!
