I received this product in exchange for my honst review. IGK Hair Look Out Lash and Brow Boosting Peptide Serum is formulated with peptides and biotin to make lashes and eyebrows thicker and fuller. This serum is very lightweight and it goes on invisible. I love how hydrated and healthy it makes my eyebrows feel. It absorbs quickly and it doesn't flake. Just apply to roots of eyebrows and upper lashes. I love how precise the brush is, makes it very easy to apply. I can't wait to see fuller eyebrows after using this serum longer.


Excited to see outcome/results!

I just got this in; so this is a first impression! I'll update after 30 days or so. Initially, this is unscented, very sensitive (didn't bother my eyes or face) and the application brush is easy to maneuver.

IGK Look Out Lash and Brow Boosting Peptide Serum impressed me with its effective blend of peptides and conditioning agents, designed to enhance the thickness and length of my lashes and brows. It's lightweight, non-greasy formula absorbed quickly without leaving a residue. After consistent use over several weeks, I noticed a significant improvement in fullness and health.

I started using this about a week ago and I'm not even kidding when I say my lashes look longer and healthier!!! My eyelashes always suck when I apply mascara but since I've been using this, they have been absolutely perfect!! I used on my eyebrows as well and they definitely grew back faster than normal! Highly recommend!
