There are sometimes multiple reasons for someone to have chubby cheeks.  It may be an inherited condition and facial liposuction may help. If it is sagging that lowered mid face fat into the lower cheek compartment than a face lift may help. ThermiTight and Ultherapy may help raise a chubby cheek but a patient has to be evaluated in person to determine if they are an appropriate candidate. In addition, some patients, especially those who chronically grind their teeth may have overworked their cheek muscles and this can be improved by seeing both a dentist and having a dermatologist or other specialist, inject Botox into these muscles.See a board certified physician who deals extensively with this condition and who does many different procedures so they know what's best for you.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.
