As can be seen on the above picture, the applicator head is a little brush. You basically put it on the upper eye lid close to the lashes as if you were putting on an eye liner, and then close the eye and put it directly onto the lashes. You can also put it over eye brows if you want.
I like how easy it is to apply, and it dries pretty quickly. But it burns my eyes when I first put it on! Not a painful burning sensation, but still does not seem right. It burns for about 30 seconds or so, then it goes away. I don't have any redness, or bumps or any other allergic reaction afterwards. I've been googling reviews for this product and lots of good things come up about it working really well and not irritating the eyes. So maybe I'm just allergic to some ingredients in it. =(
Nevertheless, I think I will continue using it for at least 2 weeks just because I'm curious to see if it actually works. Of course I will stop if the burning gets worse or lasts longer. But maybe I can build up a tolerance to it (like to alcohol) and I won't get it anymore after a couple uses! Hahaha... doubt it though. But I think this product is supposed to work because from what I've read, it contains an ingredient that boosts hair follicles to grow. Sometimes the follicles become dormant as we age. I think this is happening to some patches of my eyebrows. I probably over plucked at some point in the past, and some parts just never grow back anymore! I always have to fill it in with an eye brow pencil or powder. So I'm hoping that at least this will boost my eye brows to grow more. The painful sensation only happens to my eye lids, not my eye brows. So at the minimum I can hope to see results from eye brows.
Anyway, since I've only been using it for a day, I can't really comment on whether it works well or not. But if it does work well then it's probably a good product for its price of $49. Many other products out there that claim to do the same things can cost upwards of $100. I will have to report back!
