Review on CULLER BEAUTY Eyelash Serum: Hyaluronic Acid & Glycoprotein-Infused Moisture Retainer for Stronger, Voluminous Natural Lashes. Includes Easy-to-Apply Brush Applicator & Clear Pre-Mascara Primer. by Jamie Lewis

This lash enhancer is very moist and translucent so it was a bit difficult to tell how much was on my lashes. Decided to try it on one eye only. Immediately after applying it my eye started to burn and sting for a few seconds. After drying I applied mascara and the enhancer did absolutely nothing in terms of adding thickness as advertised. There was no difference between the eye with and the eye without. During the day, one eye happened to itch in the inner corner of the eye, and it wasn't until evening, when the itching got worse, that I remembered applying the enhancer to that eye. So definitely not for me. One thing to note is that the booster can make the lashes thicker because the product coats the lashes like a primer (if it really works, which doesn't) and if it's moisturizing it can stop breakage. But it cannot grow eyelashes. To do this, you need real drugs that are sold only by prescription.
