This serum is very oily. Too oily for a serum. It's very slick on the skin and goes on more like a layer rather than absorbing right in. It takes quite a while for it to absorb, and actually, I don't feel like it ever fully absorbs no matter how lightly a I apply it. My skin feels oily and slick until I wash it off... such as if I apply it in the morning, it'll stay greasy feeling all the way into the evening/night unless I wash my face sooner than that.
