Inner thighs

So I’m a bit on the chubby side (so my inner thighs clearly rub) I get a lot of boils aka pimples and I even have some dark circle scarring from them. It’s really embarrassing. What can I do to better this? Also, any tips for lightening dark inner thighs?

Update: thank you to those who have commented, I don’t really ever wear shorts or skirts. I wear jeans almost all the time, can I / should I still apply the things you ladies have listed below?
