Is There a Way to Reduce Facial Bone Without Causing Sagging?

I'm a 23 year old caucasion female and I'm interested in getting a chin reduction, jaw reduction, and cheekbone width reduction. My skin is thin and already sags in some places and I'm worried that reducing the bone will cause it to worsen. Is there a way to do any of these procedures without causing sagging or would I need a face lift afterwards? Thank you for reading
