We Love Eyes was created by an eye doctor, and the range reads like a clinician's habits written down. The ingredient list is defined as much by what is left out as by what goes in: no retinol, no phenoxyethanol, no CBD, and no benzalkonium chloride. Those four are the ones the founder keeps away from the lid margin in her own practice, and the formulas are built around that starting point.
Most people start with one cleanser and one tool. Foam is the easiest daily format and rinses off quickly. Oil suits anyone taking off eye makeup at the same time. The spray needs no rinse, which makes it the travel and mid day option. Once you know which format you will actually keep using, the 250mL refill is the practical way to continue.
Tools matter more than they look. The mitts and brushes are what let you work along the lid margin itself rather than the skin around it. If you wear lash extensions, or you are following a routine your eye doctor set out, check with them before adding an oil based product to it.
