It gives off a nice refreshing scent and goes on smoothly without leaving an oily or sticky feeling afterward. I noticed some changes after a few days of vigorous application. My skin has definitely gotten much softer and smoother. No new pimple has popped up as well. The light acne scars on my face have completely faded. So far, I'm getting really great results from this.
