Would I benefit from more cheek filler or a different procedure altogether? (Photos)

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

How much filler is completely dependent on the patient and injector, but it is good you started slow and can build rather than putting too much in!
You likely need at least 1-2 syringes per side more in the midface area.
However, for longer-lasting results, facial fat grafting may be a good option. Of course, a permanent option would be cheek implants.

I would recommend fat grafting combined with PRP.
provided you have sufficient fat to harvest.It usually takes more than one procedure

Thank you for your question. Of course and in person consultation is necessary for proper advice.

However I can tell you that for an effective restoration of midface fullness I typically use a full cc of either Restylane lift her Voluma on each side for a total of 2 mL

When patients insist I use less the result just is not striking.
