Review title is Tones and smooths [SEP] This is an interesting product as I have not tried a glycolic serum before this.  This product has a very slight scent that is barely noticeable. It comes in an amber glass bottle with a dropper.  This serum has kind of a toning effect on my skin.  I am applying a thin layer followed by a moisturizer and can’t believe how after just one week my skin feels noticeably smoother, much more than if I had just used the moisturizer alone.  And my face definitely looks brighter.  Last but not least, I didn’t have to use very much because it spreads well, and a little goes a long way.
