Review (3/5): Um...
I've been using this roller for a couple of weeks. I got it as I've heard that caffeine in eye products helps to tighten the under-eye area, but I haven't experienced that with this roller. It feels nice and cooling going on, but I suspect that's mostly the metal roller ball. It dries down quickly and wears well without flaking or peeling. Here's hoping longer-term use yields results.
