Can any one tell me if exposed acne treatment is good or not?

My friend told me that if I want to get rid of my acne problem then exposed acne treatment serum is perfect choice for me. But before I start using it I want to know that what it is made of? What are its ingredients,as I have a very oily skin so I don’t prefer using any kind of serums in day time. So tell me can I use it in night. Anyone who has used it tell me how to get better results out of it?
