Is a cheek lift from inside mouth or under eye if I don't want a mid facelift?

There are 2 general ways to 'lift' the cheeks or midface. One is to elevate the soft tissue on the facial skeleton and fix it to the new position. This would generally require an incision under the eyelid. Commonly called a midface lift or malar lift.
The second way is to increase 'volume' in the area to give the appearance of lift. This can be achieved with small implants to improve cheekbone contour (access incision inside the mouth) or synthetic fillers or fat grafting, requiring no scars. Fat grafting is often good for 'lifting' the cheeks more towards the midline between the side of the nose up to the lower eyelid. This is permanent unlike the commonly used synthetic fillers.

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.

Thank you for your questions. Without photos is is hard to evaluate. If you feel that your cheeks have lost volume or there is increased hollowness under the eyes then this surgery will be useful for you. This returns fullness to the cheeks and can soften the deeper lines that extend from the corner of the nose to the corner of the mouth.The cut is made under the lower eyelash margin. The fat and muscle layers are re-draped and secured. The cheek fat is dissected and secured to provide the lift. Please consult with a certified plastic surgeon who will best advise you All the best
