C-Tetra Serum

Good serum, but very oily. After application, you'll have a few more hours of oily skin that your hair sticks to. I like less.

I still had this serum lying around from an advent calendar and decided to give it a chance. First of all; I don't necessarily like the smell very much. Smells like orange and something else. The packaging is very clean, the serum has a handy pipette to spread the product. The serum is quite greasy, so you don't need much. However, I do notice that it does not absorb very well, and therefore leaves a layer on my skin. And, the day after I used the serum, I suddenly had tiny pimples on my cheekbones. So not a nice product for me, too greasy, and causes troubled skin.
