Physicians Formula Eye Booster Waterproof Ultra Fine Liquid Eyeliner, Blackest Black

I really like this eyeliner. The tip is fine and easy for me to use. The color is very bold, doesn’t skip, and makes a statement. Love that it’s waterproof. Wish it was a bit more affordable but makeup is expensive nowadays. I would recommend this.

This does NOT smudge! I used to wear Tarte Sex Kitten liquid eye liner until I discovered Physicians Formula and this is by far the best drugstore liner I’ve come across. The crispiest, cleanest line and it stays sleek all day. 10/10.

I have been using this physicians formula eyeliner for years. It does not give me any kind of allergies.. if you think it's like the best eyeliner out there.

Best eyeliner I’ve found. Better than higher priced ones.

This is the second one I've purchased that I had to throw away before finishing it. The liquid eyeliner brush tip became frayed, with stray fibers sticking out, making it impossible to apply the liner properly. Very disappointing.

This was my go-to eyeliner for years! Now, however, I only get about 2 uses before the eyeliner goes from "Blackest Black" to a faint barely there gray. How is it possible this is drying out so quickly? It's happened the last several purchases and I can no longer buy this.

This product seemed great initially. But, after a few uses the tip hairs go wild, stick out in every direction and will not go back together. This makes it impossible to apply. I loved it initially so bought it in both brown and black. Not long after, the tips went wild. I thought maybe it was a one off and ordered again. Now i have three eyeliners that are garbage.

The eyeliner is great if you get it! Have had so many problems with Walmart deliveries the last five of them… Either missing items, delivered to someone else’s house, or damaged items! I even had a driver drop one of my milks because she was insistent on carrying two jugs of milk with two fingers on one hand! Get with it guys I don’t know what the issue is

From the beginning I could not get it to work I don’t know if it was just all dried up or what but I tried over and over to get it to work and it wouldn’t work at all.

NOT WATERPROOF. This eyeliner transfered all over my eyelid. Within 4 hours I had a full black eye. Do not recommend, will return.
