I wasn't that impressed with the amount of change it gave me through out those 2 and a half months, but I would like to say that this product did its job as it claims to do.
One thing that I don't like about this product is its sprayer head. In my opinion, it's pretty useless to spray this product on the cotton pad because it gets everywhere while spraying it.
REALLY AMAZING TONER! Just in general, the whole COSRX products are amazing! I will purchase more :)
