Face cream is often enough, but if you want a separate product for your eyes, these new ones are terrific value
A hill I will die on: you do not necessarily need an eye cream. There are, I will admit, reasons why you might fare better with one. You may have a very dry eye area and oily skin elsewhere, for example, causing a skincare mismatch. Or, conversely, you may find your daily face cream is too rich for your eyes and makes them puffy, so they need something lighter. You may want a little cosmetic light reflection, or you might use active ingredients like retinol that your face tolerates perfectly well, but that your eyes can take only in a lower concentration.
It may, of course, be none of the above, but just that you find using an eye cream a pleasure, which is as good a reason as any.
