I bought this after using up my Cosrx Centella ampoule and quite like this. This is definitely more of a serum consistency, not an essence, i.e. slightly more thick instead of like water. I use 2 pumps and it covers my whole face. I really like the pump on the bottle as well, makes it easy to pump straight onto your face. This is very moisturising as it is a bit oily, although it sinks in very quickly and doesn’t leave an oily film but keeps your skin feeling very moisturised and bouncy. I tend to use this when I’m breaking out and I do find it helps calm my skin. I think I prefer this and will buy this one instead of the Coxrs one as they are similar price but this one leaves my skin more moisturised and the packaging is easier to use but still calms my skin equally as the Cosrx one
