Tiene super alta concentración de activo y deja la piel muy suave. 

It's my first time using an essence and I'm more than happy with the results, also it looks like is going to last for a very long time. Worth every euro :) 

It is the best, very gentle and smells good.

I've only started using CosRx products and this is one of their products that made me loved the brand. The snail essence has a thick consistency but it does not leave a heavy feeling afterwards. I apply it at night before my moisturizer and at day before my primer. This essence made my skin a lot softer. But for anyone looking for something to brighten your skin, this is not the product for you but this is worth a try if you want to achieve that dewy look we have been dying to have like those Korean actresses. ^.^

I was afraid it'd be gross because snail essence is mostly gooey (at least for me). But once applied on the face, it has a firming and soothing effect. I use it only in the evenings, and I use the Galactomyces Essence in the mornings.
