Easy to use eye liner
I like that this eye liner has a very fine point that can be applied easily. It is waterproof and lasts almost all day. It is a good product.

A Superior Drugstore Liner…Usually
***UPDATE: Since writing the original review I repurchased this product for the fourth time (in Ultra Black) to check again if I could make it work, since I stumbled across a couple recent reviews talking about having to shake up the pen A LOT. I am so happy to update this review to four stars. My newest one is just as deep, opaque black and smooth as I remember from my old ones. Surprisingly, I didn’t have to shake more than 20 seconds initially. So I don’t know for sure if the ones I bought before that were terrible were duds, or if some of the pens when new have to be shaken for quite a while to get them started. That’s why I rated it four stars instead of five, since there may be quality control issues. BUT I still recommend this more than any other drugstore liquid liner. It’s seriously worth giving a shot before writing it off. As for the eyelash growth claim, it is unlikely to work for that because the “active” ingredient (myristoyl pentapeptide-17) has no published, peer-reviewed studies backing it up for lash growth, although that doesn’t mean it won’t do something. It just means that it hasn’t actually been scientifically shown to do anything yet. Some people say they have noticed a difference though so it probably can’t hurt to try. But I recommend this liner because of its perfect tapered brush tip that blows any felt tip or cheap, skinny brush tip out of the water. It’s also black black black and resists smudging quite well, even on my oily lids in the heat of a Texas summer. It takes a long time for the pen to dry out, too, although after a while you do sometimes have to stop during application and shake again a couple times, but I personally don’t mind. It may smudge if you have seriously watery eyes and it does dry down to a slightly shiny finish, which you may dislike if you prefer completely matte black liner. In any case, I am so incredibly thrilled to be able to recommend this again and to use it again. I will repurchase forever, even with the possibility of dealing with duds.

It was my number one fave liner ever. The brush tip is genius. So easy to use for a perfect line, thick or thin, and makes the flick of a cat eye so so easy. This product is the reason I will never be satisfied with anything but a brush tip liner for cat eyes again. I can’t speak to the lash growing claim, but the brush tip, price, long wear, smudge resistance, and long period of use before dry out made this product a star.So what is the problem? Well, another of the winning features of this liner was that the shade Ultra Black was super super black, as you would expect. It pains me to say that, unfortunately, Physicians Formula at some point a couple of years ago reformulate the shade Ultra Black and now it is not as black. In fact, it’s not even opaque, even after multiple passes. I was so incredibly disappointed in this that I have even purchased the product multiple times since the reformulation, hoping that it was just a fluke, but each purchase has ended in a return. No more. I am also not the only former fan to notice this change. I am looking for a replacement now. So far the new fave is Kat Von D Tatoo Liner, which is a bit pricier and harder to get. Too bad.I really can’t imagine who would enjoy this product now, since it doesn’t provide an opaque line. But, I can at least still say that the ease of use and brush tip are still great, hence the two stars.

Cap pops off and dries brush, bristles bend in cap ???
I like this eyeliner – I don’t love it, I like it. I have hooded lids and it does not prevent smudges. The application is easy and great for fine lines, but the pen often blots a big glob of liner on the tip when I’m applying, which is annoying. Furthermore, the cap feels spring-loaded, and you have to make sure it is FULLY on, otherwise it will pop off, get eyeliner everywhere, and dry out the brush. That is all bearable though, until you open the pen and your bristles are all bent out of shape. This keeps happening, I think it’s a fault with the cap.

Store upside down or dry tip.
This product is great, the only down side is you have to store the pen tip down otherwise it dries out quickly in my experience. It applies very smooth, and looks very nice. It is water proof which makes it a lil difficult to get off if you mess up, use micellar water and you’re golden. It is sticky when you first apply but once dry it’s all good.

Relación precio calidad muy buena, esta marca no la conocía pero dura bastante

Soy super delicada de los ojos, cualquier cosa de maquillaje me molesta o me los irrita al punto de tener migrañas. Uso maquillaje a base de agua para que no me lastime y este delineador fue perfecto! Buen color, fácil de aplicar y se quita fácilmente con agua micelar. Excelente producto!
