Lightening from the inside out

Hello all, so like I said in my previous post, I'm an og skin lightener (still a young lady haha) but I have realized through it all that if your insides aren't right you won't lighten. I'm also into weight loss and I sometimes do fast. At the end of my fast, I always notice my skin looks flawless!

Even lighter! Then pizza or a good burger happens and I'm right back to eating junk. It happens.

My question is do you ladies do this too? Can anyone share a good cleanse or prep or even supplements to lighten the skin from the inside out?
