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...

Favorite lash serum
The IGK Lash Serum has quickly become a standout in my beauty routine. It's designed to boost lash length and fullness, and after consistent use, I've noticed a visible difference in my lashes. They look longer, thicker, and healthier overall. The formula is lightweight and non-irritating, which is a major plus for my sensitive eyes. It's easy to apply, too, with a precise brush that ensures even coverage. If you're looking for a lash serum that delivers on its promises, IGK's offering is definitely worth trying. Lovely packing and great for its value!

No harm in trying
Hair Type Wavy Hair
This one has very interesting ingredients on the list that seem worth giving a shot. However, as with all this kind of products you will not see instant results. I liked that it did not create any discomfort, or tingling sensation during application. I'm using it both in eyelashes and eyebrows, the latter I dyed and everything was OK. Overall I think it is worth giving a shot

It works, but takes time
I decided to use this product on a small bald spot on my head caused by stress. Many hair growth products contain ingredients that can be toxic to pets, so it's important to be cautious when using them around animals. After checking the ingredients list and ensuring this product is safe around pets, I started applying it to my bald spot. After a while I noticed small hairs growing back, which is a win for me!

Lash and Brow Serum
I love the matte black tube the serum comes in, the applicator that comes with it. I love that the serum does not have a strong smell. It's not overly thick and sticky when on the lash, it just glides nicely on. I have thick brows, but I've been using it to get a fuller look to my lashes.




Good serum
Hair Type Straight Hair
This is a great lash serum for those who don't want to use prostaglandins. This uses peptides instead. It's easy to use it - simply apply nightly to the lash line. Results may take some weeks or months but so far so good, and I trust this brand to make quality products. So far so good and looking forward to seeing the benefits!
