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.

I love this toner!  This was the first product that I used with AHA/BHA (I also order a few other products with AHA/BHA).  I went through purging that only took about 3-4 days luckily, and after that period my face has become SO clear, it's amazing!  This toner helps a lot also!  It doesn't really have a smell and it's really refreshing! I will definitely be buying more! 10/10 :)
