I bought this because I wanted a toner with niacinamide as one of the main ingredients.  This toner is very nice!  And it smells good.  I've only tried it for a few days, but I already like it enough to re-purchase.  On my sensitive combination skin, I haven't seen any bad reaction to the product, and my face overall looks more hydrated and brighter - though this could be because of several new products I'm trying right now.  This toner does seem more moisturizing than other toners I like, e.g. the Cosrx centella toner and the Etude House Soon Jung toner.
