You can have liposuction but this will not correct your wrinkling skin. Since your skin and abdominal muscles have been stretched by pregnancies then an abdominoplasty (tummy tuck) will give you the correction you desire.
Liposuction would definitely help improve the subcutaneous fat component but may increase your chances of further laxity and hanging skin. You may be better off having a consultation for a possible tummy tuck.
Liposuction is an excellent answer for your hips. However, the excess skin in your abdomen will require excision. Cilinical exam would determine the extent of all these procedures and if you could benefit from a mini-tummy tuck . Good Luck!
Liposuction is really "Fat" "suction" when you break the meaning of the term down. It has little effect upon skin. If skin is a large part of the problem for you, liposuction is not going to help much.
