The good: the roller-ball applicator is soothing and easy to use, though you really only need half a pump. It also did moisturize the area and make the lines around my eyes more smooth for a short time.
The bad: the product didn't lessen dark circles, and after a few weeks of use (with my clarisonic opal, no less) I haven't noticed any reversal. it's definitely just a treatment
The ugly: this is a serum and the product recommends using a moisturizer as a follow-up. i DO use eye serums + moisturizer + supergoop eye cream with SPF, and this was a disaster at blending. it would start to have a weird, flaky residue when blending multiple products. in the morning, by the time i got to eye shadow primer and eye makeup, i was using makeup remover so my eyes didn't look like they were seriously peeling.
overall: will NOT be purchasing and would NOT recommend. MUCH better products out there.
