I love this toner! Heartleaf is such a raved about ingredient for soothing acne in Korea at the moment. I found this heartleaf toner which had some pretty good reviews from Korean people so I had to try it. This toner has a slight bit of thickness to it. Not too much but definitely more than thin toners like the Round Lab Dokdo Toner and less than the Rovectin Activating Treatment Lotion. It leaves my skin feeling hydrated and calm.
500ml means that I don't feel bad for being generous with it. I like using this for toner mask packs too.
I think this Anua toner is free of fragrance and essential oils which is a plus. It has a super mild scent which I like but can't really identify (almond?). This is a similar scent to the Klairs Supple Preparation Lotion, Canmake Mermaid UV Gel, and make prem Sun Fluid if that helps. It doesn't linger at all after you apply it.
Overall, pretty good and I would consider repurchasing again.
