This is an amazing serum! I've already used one bottle up and ordered another. It is light and refreshing, has a ton of hyaluronic acid and niacinamide, but also arbutin. So it is perfect for everyday brightening the skin. I use in on my face and also on my neck and it has saved me during the hot summer month where I tend to get a couple of sun spots. I also think it great for all skin types, from dry to oily as well because it is such a light consistency. Dry skin people will need something on top, like an emulsion etc.
