Review (4/5): Clear and no scent
This serum is clear and has no scent and I've had no adverse reactions when using it. The little roller ball sometimes gets stuck which then stops the serum from going on to my skin. It's easy enough to get it to roll, but it's still a bit annoying. I can't say that there is a pronounced difference when using this serum but it does feel cool and refreshing when going on. I'd probably rather just pump the serum out and spread it with my fingers.
