What a great product (so far, after 3 weeks). I cannot say whether it wors as a lash grow serum, but it definately conditions my lashes and leave them soft and shiny. It doen't seem to have any prostoglandins so your irises won't change their colour! Yaay! (because I like my blue eyes ;)) The applicator is simply genius! It has a mascare spoolie to comb through the lashes AND a little ball at the top to apply the serum along the lash line. Love it so much!

The Kiera Blooming Eyelash Serum is a decent product if your main goal is lash health. It has a nice, easy-to-use applicator and doesn't leave a sticky residue, nor did it sting my eyes (and I suffer from dry eyes). While it didn't give me any noticeable difference in lash length or volume, it did improve the texture of my lashes. They look much healthier, softer, and more conditioned than they did before. It’s a nice lash care step, but don't expect a dramatic transformation.

First of all I need to say that I regularly use a lash growth serum and my lashes are quite long. I replaced my usual product with the Keira serum for the testing period and used the clear version every night. I had a few shorter lashes on one eye so I considered it a perfect opportunity to check Keira’s claims. Unfortunately the shorter lashes did not grow longer during the testing period and I also did not notice any significant improvement in lashes overall condition. Maybe it would work better for someone with problematic lashes?

This is more better in my opinion than the black version. I loved how liquidy it is. My lashes doesn't feel sticky since I had bad expierence using other brand and I am so glad my eyes tolerated both of the serum versions but still I prefer the clear one the most. Just like it was shown in the package it was trust that the serum helps grow lashes and I'm so happy about this product. It was so genius to add a tip sponge to reach the roots and skin. Thank you. It was a great expierence with this clear lash serum.

Really good formula, non-irritating, and good to use either day or night. In terms of product promise - don't feel like the formula had a big effect. I have pretty strong, thick eyelashes to begin with, and no severe damage.

The serum is wonderful. My eyes are very sensitive, and I did not experience any irritation when using the serum. I love the applicator. I use it every night and sometimes in the morning. I have seen some results in my eyelash growth. I will continue using it. My absolutely honest opinion is that the serum is a quality product that delivers what it promises.

The applicator alone makes this so much easier to use than similar lash treatments—the sponge tip reaches the lash base effortlessly, while the spoolie coats the full lengths without making a mess or dripping into the eyes. Formulation-wise, the combination of EGF + WIDELASH™ provides immediate conditioning slip without any of the stinging or redness that often comes with active lash formulas. It leaves a soft, glossy coat before bed and helps prevent daily breakage. Too early to judge true length/thickness (giving it the full 8 weeks for follicular turnover), but as a gentle, nutrient-rich lash conditioner, it’s a clear favorite! 🤍
