My skin is very sensitive and very very acne prone. I have tried a few Korean toners and so far Pyukang Yul and Whamisa organic flowers toners works well for my skin. It doesn't cause me to breakout. My skin doesn't tolerate Klairs products - it clogged my pores and cause me to breakout on my entire face. This toner can be layered and it is not sticky. I highly recommend this toner!
