    Best Cleanser

    I've used this cleanser just on my oily nose area for a very long time. I haven't used it on the rest of my skin as my skin is dry and mature and I felt this cleanser is for oily skin. I've just recently had an acne break out. I used this cleanser for my whole face and I couldn't be happier. The redness I had is gone as well as blemishes. My skin is smooth and hydrated. I'm glad I had the acne breakout that caused me to use this toner on my whole face. Love the large size.
