How to lighten up your knees, underarms and body effectively?

Assalammualaikum n what'dup uolls..

Lately I'm facing one big problem n it is quite embarrassing to share in public. But i'm pretty sure u already foresee what i'm talking about based on the post title above. It's i s undeniable that when u shaving a lot and it's darkening ur underarms right. Some says that it is the effect from wearing a deodorant n some says that it resulted from spraying ur perfume n some says whatever..It's a matter of fact and i believe there's somebody facing the same prob as me out there. Before this, i've been trying so many thing and experimenting my underarms with many stupid stuffs n remedies..LOL. If u ever heard that lemon, honey or even turmeric can get rid the darkening underarms, trust me they didn't work effectively. I don't know what to do.. :'(
