Unfortunately, we can't target fat loss from any one place on our body. Instead, our bodies will use up fat from all over once we start losing weight--you could lose fat from your belly, hips, thighs, or arms before it starts to have an impact on fat around your face. Stay at a healthy overall weight and your face will suit you perfectly. And one perk to having fat on your face? Wrinkles will be much less pronounced.
There's no way around the fact that, when it comes to burning more fat, you have to work at it. There is no magic exercise, workout, or pill that will do the job for you. The good news is that it doesn't take much activity to push the body into that fat burning mode. Try incorporating some type of activity every day, even if it's just a quick walk, and build on that over time as it becomes more of a routine. Do that and you're on the way to burning more fat.
