Will Invisalign help with a slight underbite? (Photo)

Growing up I never had an underbite. I had braces at 13-15 years old... of course, forgot to wear retainer. My teeth shifted into an underbite position. Now my lip sticks out on the bottom and it annoys me so much... Will invisalign help with this? Also, some teeth are on top of eachother. Will teeth on top of eachother be bad in the long run? (I need as many excuses as possible to get braces/invisalign). Thank you, BK
