I am clumsy, I am a klutz, I am impatient too and avoid liquid eyeliner. I just don’t have the time in the morning to do an eye look, then ruin it with eyeliner and need to fix it. Plus I am passed the age where cat eyes suit me, so am pretty ambivalent about liquid eyeliner, that is until recently… Having recently celebrated the FINAL arrival of Physicians Formula products in Germany, I was intrigued to notice that they have a liquid eyeliner which is also supposed to be a lash boosting serum called Eye Booster 2-in-1 Lash Boosting Eyeliner + Serum which retails for only around 10 USD. A good liquid eyeliner usually costs me more than that and a good eyelash serum way over that, so I reckoned I had nothing to lose and bought it in Ultra Black.
User experience: the pen is small and easy to maneuver, the point is a small, sturdy but fine brush tip. The product applied smoothly and easily, despite my clumsiness it did not go on messy. You can easily make your line as fine or thick as you want. I of course opted for fine. The product stayed on all day without flaking or smudging. It faded slightly towards the latter part of the day but still looked presentable.
I can not vouch for any lash growth effects as I have only used this twice so far, but this really is the easiest liquid eyeliner I have ever used. It is currently on special offer for people in the US at Ulta and if you are in Germany you can order it from Douglas here.
