Very good buy
First of all i love the fact that this toner comes in a spray bottle which is easy and convenient to use. Sometimes when i feel lazy i just spray the product on my face without the use of cotton pads. It makes my skin really soft and removes deadskin and sebum without drying the skin also i kinda feel that it brightens my skin tone abit or is it just me. Overall the product is a thumbs up for me.

Good
This toner from cosrx is nice and mild on my sensitive skin but after using it for 2 weeks i have noticed an overall reduction in both pimples and blackhead. Only negative would be that my spray nozzle doesnt work well so a lot of product is wasted. i now apply with a cotton pad to reduce wastage.

Good!

I love COSRX !!! It really suits my skin type and very affordable with high quality. I like the toner because there is no scent and didn't burn my skin.  

Didn't break me out

Didn't break me out which is always a good thing. However didn't see much of a difference to my skin so far. Need to test it out a bit longer.

Disappointed
I have a lot of blackheads and I've been using this toner for almost 2 months. I still don't see any difference...a very disappointed product
