I hate to write a bad review of this one. I LOVE the ingredients. I LOVE the concept. Everything about it is awesome... except it doesn't work for me. I've tried it multiple times, and the scent fades immediately. I have also not felt any different while using it. Maybe if I just wave it under my nose every time I'm feeling like I need to focus, that would probably be effective. But applying it to myself... it just doesn't work. :-/ Like I said, I really hate to leave a negative review. I love natural things. And this is quite natural (GREAT ingredients!). But unfortunately this one doesn't work.
