Because my skin is oily, I'm always looking for lightweight, thin, layerable products that pack a punch. This absolutely does that! It feels almost like water on the skin and soaks in so easily. You can feel it being absorbed and it's very refreshing. When it says it's a Calming serum, it means it! I love using it just because of how soothing it feels. I'd highly recommended for people with irritated or sensitive skin
