Estelle and Thild Biodefense Multi-Action Youth Serum

This product seems to have a nice effect on my skin, however it´s very fluid/runny and I find I use a lot more than a few drops to get any moisture to cover my whole face because it´s absorbed very fast in the area I apply it to. As a serum I find it´s consistency difficult to benefit from without using higher amounts. It has lasted me a little over 2 weeks which I´m dissapointed by. Too expensive for me when it´s used that quickly.
