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...

Love the IGK Lash & Brow Serum! Noticed fuller, thicker brows and longer lashes in just a few weeks. It's easy to apply and gentle on my sensitive eyes

I love the look of the tube. The applicator is nice sized. Goes on smooth. Not too much of a smell. Would buy again. Seems to work fairly well. Would recommend

Impressive Results
I received this product for free to test. To be honest, I didn't believe this product would work at first. But imagine my surprise when, after just four days, I noticed visible results—my eyebrows and eyelashes really became thicker! This serum exceeded my expectations, and I definitely recommend it for anyone looking to boost their lash and brow game.

I haven't been using this product long enough to know if it has made a difference, but it is easy to apply and doesn't bother my eyes either! The packaging is simple and the tube seems to provide a decent amount of product. I can't wait to see if it is effective.


Ingredient safe lash and brow growth serum!

Please note that I received this product for free to review. IGK Hair's Look Out Lash and Brow Boosting Peptide Serum truly surprised me. I did not expect it to work this well! I loved the formula, applicator, and matte finish on the packaging. The formula did not burn or cause a tingling sensation on my eyes and even when I accidentally had some in my eyes. The serum does not smell like anything. The serum did not weigh down my eyelashes. Instead it felt comfortable and invisible. The formula dries down very quickly. The silicone brush-like shaped applicator made application very easy. It perfectly hits my targeted areas without any mess. After daily continuous use, I noticed hair growth and thickness on both my eye lashes and eyebrows. To ensure product placement on my eyebrows I use a spoolie to brush out any hairs in the way. I would like to note that because the packaging is a matte finish, it will have fingerprints all over it. Comparing to other lash and brow serums, the value of the product is the same. Most lash and brow growth serums have about 3 mL of product in them. The ingredients are clean and eye safe. The serum did not irritate my eyes but please patch test beforehand, just in case and stop use if irritation occurs. Overall, I would definitely recommend the product and repurchase.
