When I was in college, I used to break out a lot. I started using this product that was made in China - I forgot the name already. They said you'd normally break out for the first 3 weeks and after that, it would subside. Sad to say, 3 months later I was still breaking out. Arrgghh... I wished then that I could afford a best acne treatment. I would have eliminated all my acnes. It has left some scars actually. But now that I can at least afford to buy stuff for my face, I would go for a water-based product because my skin is oily.
