Works But Slow Results
I received this product complimentary for my honest review. I love my lashes and brows so anything to make them appear fuller and longer I'm all about. I've tried other brands of peptide serum and eye brow and lash growth products and felt this product was pretty on par with some more affordable bra...

Extremely effective and noticeable difference! Works very well and has clean ingredients. Packaging is nice and sleek and compact so it's easy to travel with as well!
Pretty good but can leave a residue
Really love the applicator. The serum goes on clear and doesn't take long to dry. If you put too much on when it dries, there can be a residue. This isn't the best brow serum out there, but for the price, it's pretty good. There's no scent and it didn't irritate my skin

Gorgeous results
The packaging of the product is matte, it looks sleek and elegant. The scent is of a clean serum. I like that the ingredients include biotin, as it helps with the growth of hair! It defensively is effective by using it every day, it makes my eyebrows look and feel full and gorgeous!
Worth the try
Hair Type Very Curly Hair
So far so good. Packaging is nice. It does not have a chemical smell like some others. Not really sure about the true benefit of use as products like these time some time to show results. Seems like a good value.
Effective and Easy to Use

* Received this product for free from IGK exchange for my honest review * I used this on my eyebrows, which had thinned a lot from bleaching them several . I saw results by the 2nd week after using it twice a day and have already found AMAZING results. SO GOOD. My eyebrows were starting to recover and look thicker, and hairs were growing back in the bald spots. It is definitely one of the best eyebrow serums on the market. Which I love. I would highly recommend. Thank you IGK for giving us a product that gets the job done !!💕💕💐💐
