I am in love with this awesome serum, it is so simple to use and works amazing. I have been using it for about three weeks and have noticed great improvement in my brows. I do use it at night as I work at home on the computer so don't want to risk it drips into my eyes but love wearing it at night. I don't really use it for my lashes since I do have quite thick lashes but my brows are very sparse and since using I do notice them filling it.
Now, don't get me wrong it works great, but of course as with anything it does take a while to see the growth. I have been using it for three weeks as I said, and I have noticed a bit of growth. It's not like you have sparse brows one day and then a field of them the next but it is improving and there is no irritation from the serum so I am hooked on it.
