It can do a hell of a lot of other stuff, too, like reduce redness, soothe irritation, heal cuts, and reduce oil and inflammation.
Promising review: "I buy this when my other bottle is only half empty — that's how much I don't want to be without it. The smell is so good that even if it didn't work amazing wonders on my skin, I would use it just for that. But it does work! Because of this toner, my skin is brighter, more even, and just plain pretty. It feels moisturizing and clean, without giving your skin that tight feeling. I have pretty sensitive skin, but it doesn't burn at all. It tightens pores and helps with all skin needs, whether you break out a lot, are young or old, or have dry or combination skin — it's universal." —Gail
