Fade acne scars within a week?

I've got a very important party to participate next week, therefore, I would like to fade acne scars around my mouth as fast as I can. Thus I visited my girl friend, Natasha, and she is a well known make-up stylist and also the nutritionist in the town, I learned a lot of knowledge from her on fade acne scars with natural ways.I hereby list all the tips I learned below.
Fade acne scars with lemon juice
Yes, lemon juice is rich of vitamin C, and vitamin C does have whitening effects. Therefore, applying and massaging lemon juice over your scars and intaking some lemon juice daily with your meal will help you to fade acne scars. My firiend also told me the secret that lemon juice will nutrition your hair if you wash your hair with it. Some one may say the lemon juice is too acid and it may be bad thing for you delicate budy skin. It can be assured that vitamin C is nice stuff to our skin and so the lemon juice is also OK to be used with our face.
Orange peel may be helpful.
The old used to use orange peel, and it does work for some people. However, orange peel does not smell good, and some girls just cannot stand the smell. Maybe some men may stand the smell and they can use orange peel as a try, if it does work please let me know in below comment.
Aloe Vera is also often used to fade acne scars.
Almost everybody knows Aloe Vera, and it is most commonly used in beauty, although it is not a very beautiful looking plant. Aloe Vera juice from the stem shall be coated to your spot and scars, and massage it gently.
Cocoa butter will be helpful to fade acne scars
100% pure cocoa butter can be applied to your scars and gently massage the skin with your finger 5 times per day. The cocoa butter must be the pure one, not cream, and there must be no additive in it. The reason for this is cocoa butter with preservatives will do harm to your skin. The massaging action is very important in this; make sure to do it for a couple minutes each time. You will totally fade acne scars.

She also told me that tomato slices, turmeric, home made face packs and papaya juices are also helpful to fade acne scars and have the similar outcomes, if you like you could try them all.
