Love it! I have sensitive skin, I also have eczema even though its not on my face. On the other hand, I also have a rather acne prone skin, big pores, and, oily t-zone -- making  it really hard for me to find a good but gentle enough peeling toner. But oh God, this toner does wonder. I use this only once a day (before bedtime), applying with cotton pad and tapping in the excess toner that are left on my skin. Then I do the usual gentle and calming and hydrating routine with hydrating toner, serum, and sleeping pack. it really improve my texture and even help with the white head. i don't really see a difference with my pore size, may be because i have only just use it for 2 months.
PS : tried to use this twice a day (in the morning to cleanse face -- because i don't wash my face with soap in the morning, i usually use micellar water and then rinse it, but i think my skin is too sensitive so i can't tolerate it. i went back to use it only at night, and its back to be amazing again. so i think, don't overdo your acid toner when you have sensitive skin.
