Never really incorporated an essence into my routine but after going through a full bottle of this I must say it really does make a difference. I have dry acne-prone skin and this essence helps keep my skin hydrated without breaking me out . The product also feels great on my skin and meshes really well with the rest of my skincare. I usually like trying new products but I'm definitely repurchasing this! So far Cosrx hasn't made a product I don't like.
