I love this product, not as a toner but just as water to wet my face to soak my other products in. Tap water that doesn't go through a water softener is pretty harsh on my skin so this is a good alternative for letting soak into my skin.
I mean, you're paying for bottled spring water. It's not overly expensive, but it doesn't have any extra ingredients that are proven to target specific concerns other than a base for products for those with sensitive skin like myself.
