Strengthens Lashes

I have skimpy short lashes and always have. I started using this and the esthetician who does my lash lift noticed a difference in my lashes. It won't give you the long luxurious lashes you long for, but it will improve the quality of the lashes you have.

Great product 👌

I have been using this product, everyday, for a long time. My family have noticed the difference on my eyelashes. There are healthy and longer. I use it in conjunction with the mascara. I didn't give it 5 stars because ASA I stop using it, my eyelashes don't look the same. It is the only product that dosen't irritate my eyes if I get to close to my eyes.

Haven’t seen results in two months

I’ve been using this every night and I am just about out. But I haven’t seen any results. The brush is very very thick, and covers a bit of my eye lid too. I’ve used an eyelash serum in the past before and saw results definitely after four weeks. I wanted to try this brand because I love some of their other products. Unfortunately, I haven’t noticed anything at all. They still look short to medium length.
