I haven't bought this through Birchbox before, but I have some at home. I know a lot of people don't understand the hype of this product or just think it's fancy water, but for me it's not. I live in Texas, in the most drought stricken area possible...our city recycles the sewage water directly through reverse osmosis..you get the point. Anyway, our tap water is bad. Very bad. It's hard, and is horrible for my skin. This product saved me. I use it to "cleanse" after bathing. It's great after shaving to rinse harsh water off and after washing my face with tap as well. Also, it's a great makeup setter because it doesn't add shine and stickiness, it just makes me look more natural. I am very simple with my skin care, but this stuff is a luxury I will always find essential.
