Online ebooks with programs to help clear skin?

Hi I'm a 17 male with oily skin and bad acne. I came across some sites promoting ebooks which promise to help solve Acne problems. I am a student and it's almost impossible for me to pay so much for a book, so I was wondering if anybody knows how such programs work?

How do I really achieve clear skin? I started having pimples/ Acne since 13 and it has really affected my life. I feel so embarassed whenever someone talks to me that I dun look at them. And I feel bad for them to look at someone who's so ugly. I know having clear skin will not make me look any more handsome than now, but I will be able to life my head up whenever I walk down the road.

I really hope someone really helps. Thanks.
