When we saw the latest photos of actress Renee Zellweger we couldn't help but wonder just what the star has had done to change the look of her ace.

We couldn't pinpoint exactly what or if she had any particular procedure, so we decided to tap Dr. Victoria Karlinsky of New York City; a highly-skilled, certified trained facial and body sculpting specialist.

What can we learn from procedures that dramatically change the look of a person?

I think in this day and age, most of us who utilize aesthetic procedure simply strive to look fresher and more youthful, not different.

Any tips for women looking to undergo similar procedures?

My suggestion is always to be conservative. Don't try to look 20 if you are 40, simply strive to look fabulous for 40.
