24. Fade Dark Spot
The acidity of lemon turns it into a bleaching tool that will help fade away any dark marks or spots on your skin. It can also help fade scars, but make sure not to overdo it so as not to burn your skin. Just dab some of the lemon peel onto the areas you want to lighten, and then wash off in the morning. But watch out: lemon makes your skin very sensitive to UV, so make sure you don't go out in the sun afterwards or you can cause burns.
