I have been using this astringent from Biore for a while now. The bottle used to be green and I couldn't find it to repurchase! Then I realized they changed the look of the bottle. Astringent is used after you cleanse your face. I take a cotton round and soak it with a little of this Biore solution. I swipe it onto my face to get rid of any extra face wash that may have lingered. Astringent shrinks the size of your pores and gets your skin prepared for moisturizer. It sounds so silly but it really makes your skin feel clean and clear. I love it!
