I use the Seoul Cleansing Balm frequently on my waterproof eye makeup and for a regular cleanse. I haven't tried the Zero balm so can't compare with that but the Seoul is my favorite of all the balms I have used. I use several eye liners that are really hard to remove and also some mascara (I sweat!). This balm doesn't irritate my eyes or lids and melts well on me. I don't lose a lot of lashes with this balm. Just sharing my experiences.
I keep a stock and mine is already on auto delivery so will compare this value and go from there.
If my dog doesn't like you, neither do I.
