How does Lemon juice work to get your pimple scars away?

Plz help and does it really work and how long does it take to work??How does Lemon juice work to get your pimple scars away?
Lemon juice will fade and whiten the scars so that with time they will not be so noticable. How long it takes depends on how often you do this. You can do this everyday, several times a day. Either with a Q-tip or rubbing a slice of lemon on your skin. I hope this helps.
