I have Invisalign but lower teeth were overcorrected with lower lip collapse

I had invisalign for the past 3 years for overbite,,and I find that my bottom teeth has gone in a lot - resulting in a collapsed look (my lower lip just collapses without any support when in rest giving me a older look). Also, my top 4 teeth still has a overbite. i notice that when I wear my bottom retainers, my lower jaw looks better (maybe with additional support). I am looking for a cosmetic dentist with a holistic perspective in Bay area, California. (near san francisco)
