I have also experienced having severe acne this past few years. It's not nice to look at, it also covered my entire face! I really wanted to cure it faster but unfortunately, it didn't happen. I tried a lot of products but none worked!
  Now, it's getting better, it's almost gone. I'm using Puraskin Acne Treatment for my acne. But I'm not trying to say that a treatment may be effective to one, and also to others. No, treatments vary due to skin types and severity of acne.
