what are the applying procedures

Also, do you rinse it off or wipe it off with a tissue? Also, about how long does it take for it to finish?

ok so im clearing up my acne at the moment i just did the lemon letting it sit on my face to clear up the scars as much as possible i still have a few small pimples though should i put some benzoyl peroxide acne cream on before i go to bed?

i have two acne scars. one on the side of my nose and one on my cheek. if i apply lemon juice everyday before bed, how long will it take to make it disappear.

Does it work? Does it matter if you have dry skin? When you stop using it does your face get worse? If you can answer any of these questions it would be greatly appreciated.
