Is there any effective home remedies that is good for lightening acne scars?

Lemon juice is ok, it depurates and cleans your skin. I would suggest you to implement 3 things: 1) Mix a natural yogurt with wheat flakes. This you can scrub it in your face and will act as a mild and nutritive exfoliant. 2) Scrub half lemon on affected areas 3) Cut an aloe vera leaf in half and take the crystal part. This crystal has many healing and scarring properties. Try this if you want to maintain yourself strictly "natural". Using this you can have some mild results but you are never going to get rid of your scars totally. Chemical peels and other aesthetic treatments would. Glycolic acid (also natural, gotten from fruits) is highly used in chemical peelings and exfoliates your skin deeper making your skin to renew itself. This will give you better results if combined with the above.

Drink plenty of water. Staying well hydrated can help your condition improve, because the "waste management" control system in your body requires a lot of water to do its job. Without enough water, the body has difficulty removing some waste products efficiently. Look for face washes which contain the active ingredient benzoyl peroxide. This is the key ingredient in some of the best face washes. use a 5-10% benzoyl peroxide of mild to moderate acne and 10% for severe. Try smashing one tablet of aspirin in a small bowl, then adding lemon juice to the mixture. Aspirin is acete salicylic acid, chemically related to salicylic acid. Apply to the affected areas overnight. It boosts the healing process while reducing redness. Try putting toothpaste (paste, NOT gel) on your face, cover it with a bandage, and keep it on all night. When you wash it off in the morning your acne will look better. The astringent and surfactant nature of the toothpaste will help diminish the appearance of pimples. But the toothpaste has been known to burn sensitive skin of the face, so be careful. If your face does burn, stop acne treatments and work on healing your burn.
