Will this get rid of acne scars?

if i alternate putting lemon juice on one night and tomato juice the next night and then lemon juice again the following night...etc...will it fade my acne scars? i will wash off the lemon/tomato juice after about 20 minutes and then apply a plain yogurt mask...and then wash that off after 30 minutes...and then go to sleep...will this help reduce acne scars and how long till i see a difference?
