Hollow cheeks refers to the sunken appearance that happens with aging or little body fat. The cause is by having little fat in between the cheek bone and jawline. Other causes can be due to poor health such as dehydration or HIV lipoatrophy.
Non-surgical options for correcting the hollow cheeks area include dermal fillers, Sculptra and PDO threads. These options are safer than surgery and give you immediate results with little to no downtime.
