Odacité Eye Contour Serum Concentrate (5ml for £43)
I have the version with the roll on ball and not a dropper. There is some scratch on that ball that seems to be uncomfortable on the eye area, so I just first roll it on my finger and then work it in (problem solved!). It's oily, and it does take a bit to sink in. I do like the extra kick for my eye care, but after a month of usage, I don't see any real impact.
