Buccal fat is the accumulated fat in your cheeks. Many people are not comfortable that they have cheeks that are too puffy or fat. It makes their entire weight loss regimen look futile or makes them gain the â€œchubbyâ€ image all their lives. The so-called â€œchubbyâ€ or â€œchipmunkâ€ cheeks result to conditions such as being overweight. Genetics also plays a significant role in having this type of trait. This is why buccal fat removal is gaining popularity.
