This is my first try at hydrating toners and I truly was not disappointed. I like that it is in a spray bottle because it makes it easier to apply and evenly distribute all over my face. Also, I love COSRX for always incorporating ingredients that help problematic skin. The centella ingredient is good for quieting down inflammation from acne or pimples. All I do is soak up a cotton pad and apply it on area where I have any redness. You can notice the redness receding within just 20 minutes. Definitely a toner I would repurchase.
