It is a good product, but not my "holy-grail". The hydration doesn't last too long even if you use the "7-skin-method" so i recommend using with another moisturizer to lock all the hydration into your skin before you went to bed.
At the morning, you can use this product after washing your face and go straight to the suncreen step if you have normal to oily skin.

After using this for a few months, I thought I like it more than my Soonjung. But when I decided to change back from using Klairs to Soonjung again just to remind me the difference of the two before I make my mind, I realized that this toner doesn't make my skin hydrated the way I want it. Something about the texture of the toner that just emphasizes my skin texture and instead of hydrating it, I always feel like I need to layer it again and again because it disappears quickly leaving dry and tight feeling on my skin.

I'm definitely not sold yet on this toner. I will try tweaking the products I layer with this toner in the future but so far, my skin is just not impressed.

Lovee this toner so much ! One of my favourites. It helps to bring back moisture into my dehydrated skin and plump them up. It’s soft and has no scents which i prefers because of mu sensitive skin. It’s also fungal acne save ! I recommend for you to tried it !
