Would Invisalign fix my underbite, frowned lip, and side profile? And what are the effects? (Photos)

Hi, my dentist said Invisalign would be able to fix my underbite. He said that the bottom teeth will be bended backward to let the top teeth bite over it. Before making a decision I would like to understand a bit more and get different opinions. Would Invisalign fix the frowned lip I have whenever I bit my teeth all the way? And would it fix the side profile where the lower chin and lip is over upper lip? What are the side effects i may have from Invisalign? I would like to avoid surgery.
