Am i having a bad reaction or is this just the beginning stage and my skin's gettting used to it?

Hi My friend had severe acne both on her face and back and after trying counless of dermatologists' treatment options, she still found herself very frustrated. Until she located a book that showed her a holistic way how to permanently Cure her Acne within 2 Months. The book showed her how to eliminate blackheads, excessive oiliness and redness. She was really excited that help to remove most of her scars and Acne Marks.
