Radiesse is a great option to build volume and help with facial contouring, though it’s not a permanent filler, it can typically last 8-14 months depending on the area it was placed. I suggest you seek a qualified plastic surgeon and schedule an in-person consult
I have a few points of recommendation for you based on your photo:
- Your lower eye bags can be corrected by transconjunctival blepharoplasty
- The flat mid-cheek can be augmented to comparable results with either implant, fat transfer, or permanent fillers
- Your cheek is not so hollow, but if you are concerned about this, fat transfer or permanent fillers is the solution
- Your upper lip can definitely be augmented by fillers
With regards to your sleeping position (prone), it will be best to try sleeping on your back with an elevated head as this will be recommended at least 1 week after the procedures recommended.
I would start off with some fillers to add volume to your mid-face and to your chin. You should get good results. If you have to continue getting fillers and you really like the volume you might consider something more permanent like implants or long lasting/permanent filler but I would not start with that.
Even though the pictures are not of the best quality for aesthetics evaluation, you have lost volume in your medial, central and zygomatic cheek making you a great candidate for fillers.
The photo you sent is not great to evaluate, however, it does appear that you would benefit from volume to your face. You can achieve this with cheek implants or filler. Your cheek area does seem flat, and implants may be your best option. In addition, (again, the photo is not great), it seems your chin is small or receded. Adding a chin implant or filler to this area will balance your face!
