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 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.
My acne and whiteheads have definitely decreased. I like to just spray it and pat the the product on my face however, it does sting my eyes when they get in contact with each other. And I love how the product is odorless.
