lemons lightens hair, lightens skin, conditioner, face cleanser (from what i gather more or less), can be used as some sort of soap, and much more? wow nuts. though i heard that lemons can act as an acid and a base at the same time. i don't get how, and i'm not all hyped up to look it up. aiya, some people like to stay fair, or reach fair "colouredness"... it was once considered as being asian beauty... or something along the lines of that. personally i use it to laugh at my close friends after they get super tanned =P
