The Medicine Net article below has some detailed information on the causes and cures for acne including diseases that mimic acne and lifestyles that affect it. If you read all of the info, you will be an expert on the subject.

To finally get rid of my acne, I went to Walgreens (any brand will do) and got old fashioned, store-brand 10% benzoyl peroxide and started slathering it in heavy, heavy amounts all over my face twice a day. I used a gentle cleanser, tons of a gentle moisturizer, and lots of sunscreen. I was clear in about about a week or so.

Now I just use it every few nights to keep my face clear.... and I'm figuring out what to do about the scars besides slather makeup over them.

I did something very similar to what this professional makeup artists/esthetician suggested:

Here's the proper way to get rid of acne. In the morning, wash your face with your own urine, making sure you pay attention to the spotty bits. Rinse it off, repeat every morning. Your urine excretes all the hormones that your skin needs to stop acne (that's why you're getting acne) and this will clear up 9 out of ten cases of facial acne, in 4 or 5 days.
Doctors will give you all sorts of bogus acne cures, there's big money in it. Why would they want to cure it? Try it. It will work. Or don't try it, and suffer with acne for anything up to 5 years instead. What do you have to lose?

well I use green lemon it does work,but you have to put it on your face every night and sleep with it,and wash it off in the morning :)
STEP 1: put lemon starting fron your chin.
STEP 2: than do your cheeks.
STEP 3: and then on your nose.
STEP 4: and then on your forehead.
And thatz it ,and when you do it in the forhead throw it right away!!!!!!!!!!1
Hope it works:)
