I love using this eyelash serum. It was easy to use and was not irritating at all to my eyes. I put this on like I would mascara, but there is an extra ball at the end of the wand. My lashes does look slightly longer than normal.
100% Slept on. New fave
This is my second time trying UB, and the first time I've tried this brand, but I absolutely want to check out their other products after this. It did still come later and was delayed in transit compared to the Ulta app, but it was definitely a shorter shipping time than the other product I tried from UB, so good on this brand for being more on top of things. Now to the product: this is now going to be my new go to lash serum. I have deeply hooded eyes with epicanthal folds. I struggle to use false lashes so I often go the 'eyelash serum' route to amp them up a little. I've tried maybe 6 or so, and every one has had a very expensive price point, the "thin brush" style applicator, and often burns, makes my eyes water (leading to burning), or causes irritation in general. This one has a GREAT price point, and doesn't burn or heavily irritate at all, even if you accidentally get it in your eye. But my FAVE thing is the applicator. Instead of the tiny lash brush I've almost always gotten, this one is like a traditional mascara wand, with a tiny sponge on the end. You can run the little sponge on the base of your lashline and even on your waterline. Then comb in the serum like you would with a normal mascara. The only thing that bugged me about this product was it could get a little 'crusty' if you over-apply. That's it. And that's an easy fix. I also like how the mascara wand shape "pulls" your lashes up for an instant bump before you get the long term benefits. And just on a personal note, I am a HUGE K-beauty fan, but as a Eurasian woman, many products/brands don't cater to my skin tone or eye shape. Even the K-beauty lines popular in the US don't always sell the specific shades I need, or more diverse eye shapes. I love that literally anyone with eyelashes can use this product. To me personally that's VERY big, so I wanted to shout them out on that aspect.
Love the brush
Lightweight and easy to use. The dual brush is great to get the lash line and all lashes. I accidentally got it in my eye and its does burn a bit so be careful with the bulb tip.
Would buy again!
It's been years since I've used a lash growth serum and I'm happy to see more brands creating newer and better formulas. I love the brush that this one comes with. It has a ball at the tip so that you can grab the small lashes at the inner and outer corners of the eye. I started seeing results after just 3 days with more growth everyday. There is no fragrance and smells very neutral. The formula is not very wet so it doesn't drip into my eyes. Excellent product.
