Pros: my lashes got longer and seems to curl slightly up on their own. Love them.
So-so: lashes got longer but not noticeably thicker. My eyebrow hairs grew a little bit where it was sparse, but not by a lot.
Always some itching after application. I use it until I notice the wrinkles appear. Then I stop until it goes away. Then I use it again until I notice the wrinkles again.
