I have very chubby face.I m just 22 yrs old but due to my bulky face I look much bigger. So advice me regarding reducing face fat.

Well to begin with, you are probably just being too hard on yourself, and are just fine the way you are, but I know you don't think you are.

Facial exercises could help you some. I would start with that. There is something I saw on TV one night, not too long ago. I don't usually pay much attention to these things, but there was a commercial on for something that was called "Face Master" It was Suzanne Sommers, and I guess her take on the thigh master for your face. It caught my attn for a sec or two, but I didn't pay any attn to the address or how it works. Try googling Suzanne Sommers, or Face master, and you might find some info!

Hope that helps you some, and good luck!

Avoid having oily foods & milk product food..
Follow some diet to reduce the weight...

You could try contouring your face with makeup. Here is a video on the how to's YouTube - Contouring & Highlighting

Make up is really a great idea, but if it's seriously something you can't live with, a good facial cosmetic surgeon could do facial liposuction.
