I bought this in a double pack from Sephora. 1 was the lash serum & 1 was the brow serum. The lash serum worked, but the brow serum did not.
I have damaged follicles making it pretty much impossible for my brow hairs to grow. I've tried several serums & none of them have worked. This tube was 2+ months of use & I got maybe 2-3 hairs on each brow to grow. So I think this is my last purchase of any kind of brow serum.
I gave this 3 stars bc I think if you have healthy follicles, this could work for you. It's kind of a pricey gamble, so I would suggest getting the double pack like this. Both tubes will last over 2 months.
