This toner is definitely too strong for me. I've always had oily skin, not too much and mostly in the T-zone, and pores and greasiness have always been my biggest concern. I tested this toner out and I could only keep using it for a couple of days.
It's a spray and as soon as I applied it in my T-zone, I could feel my skin immediately super dry and that's not a good sign for me. I need a gentle toner that properly hydrates my skin, not an astringent that dries it off. I even tried to apply a fewer quantity on two different cotton pads and, believe it or not, I could feel the skin on my fingers close to the pad immediately reacting as I wrote above. No results at all.

For a long time I was looking for cheap, low pH toner in spray. So this is it for me. I use it after cleansing my face, both - morning, evening. The application is fast - I usually spray with this all over my face and then I gently spread it with hands. It's nothing miraculous, but I wasn't even expecting any huge improvements with this - I just wanted something what will work with COSRX's exfoliants. I will buy ti again.

This product is a part of my daily routine for 2 years. I have oily and acne prone skin. I bought it because it was the only available toner with low ph I found. It has been working for me. It doesn´t break me out, it does not clog my pores. It does not make any miracles, but it works..

I bough this product because it was one of the most hyped product in Poland when it was released and first two weeks it really worked but later - something started to change and the change wasn't good. I had more acne than before, it's a cheap toner and honestly if you have an option to buy a better product than this - do that, this Ziaja toner is not even worth a try.
