This is one of those cult products that everyone should start using the very first time they get in to Asian skincare and build up a routine. I have ordered it and been using it for two weeks and I can definitely see my skin improving - it is brighter, moisturised and extremely soft! I put a pea-size amount of the product on my face in PM (after VitC) and AM (before sunscreen) and never feel irritation, itchiness or heaviness with it under a lot of make up. It feels a bit sticky on my face while it is being absorbed but this hasn't bothered me. Would definitely recommend!
