Is thin skin (almost no fat) a good structure for injecting fat?

One of the benefits of a fat graft is that the transplanted fat actually incorporates itself into your skin and resvascularizes there, which will strengthen and plump your skin. So, actually, it’s quite good for thin skin to have a fat graft! One caveat is that some of the fat will die. In fact, I actually think most people get a better result when volumizing their skin using a dermal filler such as Voluma, or a collagen-stimulating dermal filler such as Sculptra. The only way to be sure of which is best for you is to consult a board-certified dermatologist.

Contour irregularities in the cheek following radiofrequency can be successfully treated with fat grafting.  I would suggest you see a board-certified plastic surgeon for an analysis.

Hello! Fat grafting is typically done more deeply in the midface and should not be visible even with thin skin. That being said, it is still a risk, and more importantly resorption, asymmetry and longevity are all variable and unpredictable. I typically start with volumizing fillers such as Voluma for midface improvements, or for significant loss of volume, implants are sometimes an option for permanent correction. Good luck!
