How to whiten dark groin and inner thigh and the butt gluteal area? Am light or fair skinned Asian Filipina? (Photos)

Dark skin started when I was still a child age 10. Am 56 years old now (present photo). It was the time there was an outbreak of scabbies brought about by those vietnamese refugees accepted by the President for asylum. Our community was affected. It was cured but once fair smooth skin turned dark and there was the presence of somewhat white skin flakes which causes itchness and redness when sweating.
