How risky is it to get fat injected directly back to buccal space due to inner mucus and bacteria?

Thank you for submitting your question and photos. You may benefit from a buccal fat pad removal in the cheek region to balance the proportions of the face. Removal of this fat pad can reduce fullness in the face to create a more defined contour in the cheekbone area and along the jawline....

Bichectomy is a procedure where excess cheek volume is removed. Therefore, facial roundness reduces, and cheekbones become more prominent. Buccal fat removal is a permanent solution and once the fat is removed it will not come back. Best wishes.

You might consider fat transfer to your cheeks and tear trough to volumize the mid face. You can hold off on buccal fat reduction for now.

You can consider buccal fat reduction. However, I would be very conservative in how much I remove. Else, it can cause hollowing as well feminization of the face

Based on your front view, you are a good candidate for buccal fat reduction. It's hard to tell about botox to masseter without more pics and info. However, you can always stage them since they address different portions of the face

You can consider buccal fat reduction. It will help with lower face fullness. However, it won't prevent jowling down the line since those two are not related.
