I bought this toner because my skin is very oily but also sensitive, western treatments were always extremely harsh with my skin. Although this is recommended for people with acne which I don't suffer from, it has turn out to be incredible good for reduce overnight any kind of inflammation in my skin, for example small hormonal pimples or irritation. My oil production was not dramatically diminished, but it's a little bit less that what it just to be.
If you have sensitive oily skin I would definitely recommend this product.
