How Much is Too Much?

I've been thinking long and hard about consulting a facial plastic surgeon. But I don't know how many procedures a person can typically get in one visit. How many procedures can the body tolerate? I was considering getting: upper lower bleph, malar cheek implants, neck lipo(w liposculpture & jaw contouring) A little about me: 20 yrs old, with a round face with hardly any bone structure in the cheeks, tired looking eyes, a lot of fat sitting under the chin/neck area. I've tried diet, exercise.
