@feruze-- It's not bad! Whether you want to use it or not depends on how your skin is doing. If you don't have much blackheads or enlarged pores, you might not need clarifying lotion. Perhaps you have combination skin and not oily.
I use it every morning after my gel cleanser and before my moisturizer. I prefer an acidic formula for my clarifying lotion. Mild ones are better for those with sensitive skin. I have such oily skin that if I don't use a clarifying lotion, oil builds up in my pores and I have many blackheads and visibly enlarged pores. It doesn't look nice.
I noticed how problematic skin was when I came across a dermatologist in a pharmacy. They were doing these complimentary skin tests with a device that is held to your face and enlarges your skin on a screen.
If you are not sure about what you should use, talk to a dermatologist at a pharmacy, they are really helpful.
