“The texture is quite watery, and the scent of this product are kinda like oranges. And it does not leave any stickiness afterwards. Which I quite in love with it, because normally those right cream are quite thick and leave stickiness after apply. Instead of saying this night cream are watery, I might says this night cream are more like gel type. It doesn’t caused irritation or acne. I love to use this night cream while my skin are lack of hydration. This is a good product to use when you need hydration and brightening effect, this would be hour life savior 🙂 Credit to
