Physicians FormulaEye Booster, Lash-Enhancing 2-in-1 Eyeliner Serum, Dermatologist Approved, Hypoallergenic, Cruelty-Free & Vegan - Deep Brown

I am by no means a make up artist. So I need products that look good AND are easy to use. This eye liner was a game changer for me. Before I had only used pencils or brush on eyeliner. The pencil did not stay long enough or leave a dark enough impression to show up. The kind with brushes were difficult to paint straight lines on. But this product is like the perfect combination of both. It handles like a pencil, but makes an impression like a liquid brush. So easy to use and create nice lines. The pigmentation is perfect and it does not rub off easy.

This has to be my favorite eyeliner pen! I have very sensitive eyes and have to look for washable liners that also stay put and don’t smudge. This is not easy to find but I have found it in this eyeliner! It glides on with ease, the color stays and it looks beautiful! I find it holds up all day although sometimes I may need to touch up my wing before going out for the evening after wearing it all day. Highly recommend!

I finally pulled the plug and bought a KVD Tattoo Liner and I regret it. This product is easier to use, is also a brush, blacker, and consistently more fresh than the KVD option which are notorious for being dried out upon purchase. Save your money, this one’s fine.

I wanted to share my thoughts on the Physicians Formula Ultra-Fine Liquid Eyeliner in Dark Brown, and I must say, it's been an interesting journey with this product. Let's dive in with an honest and friendly chat.First things first, if you have sensitive eyes like me, you'll appreciate that this eyeliner doesn't provoke any itchiness or irritation. That's a big win in my book, and it's why I keep coming back to it.Now, onto the performance. It's not the absolute best eyeliner I've ever used, but it's pretty good in terms of longevity. It won't smudge on you, even on sweltering days, which is impressive. However, there's a catch – it does have a tendency to crumble if you touch it. So, if you're a habitual eye rubber, you might want to be cautious.The color, a lovely dark brown, is fantastic. However, it doesn't always come out as pigmented as I'd like. You might need to apply a few coats to get that rich, intense look. Also, be prepared for the pencil to dry out faster than you'd expect. That can be a bit frustrating, and it does make it pricier in the long run compared to non-liquid liners.But wait, there's a trick! A little shake-shake before application can work wonders, as some recent reviews have mentioned. It might take a bit of extra effort, but it's worth it because the brush tip on this eyeliner is a game-changer. It makes creating precise lines and those sassy cat-eyes a breeze.In the end, I'm in a bit of a love-hate relationship with this eyeliner. It's a dependable, wallet-friendly option for sensitive eyes, but it does have its quirks. If you're patient and don't mind the occasional shake, it might just become your go-to liner. As for me, I'll keep using it while I search for that perfect, hassle-free alternative. Happy makeup-ing, friends!

Hi all! Recovering Kat Von D tattoo liner user here. I do not want to support her further, so after 10 years of using that eyeliner, I went on the hunt for a liquid liner than could compare. THIS and only this product come close for me. I can work a 13 hour day and my eyeliner stays! the applicator is basically the same as tattoo liner, its BLACK, and its obviously much cheaper. I will say, if im SWEATING (GA or NC heat/humidity) I will lose the part in the corner of my eye, but only if its a lot. I feel like they also last a good while as far as amount of product. The packaging is also kinda fun!

Applies pretty well, is water RESISTANT (not proof, will still run if you're submerged, but was fine when I got caught in rain or splashed with a drink). Drips horrendously though, like ink all over the inside of the lid and the sides down from the brush. Dries out pretty fast, too.

This Physicians Formula Eye Booster eyeliner is one of the best I’ve used for precise and clean lines. The super slim tip makes it incredibly easy to control, even for detailed wings. It dries quickly and stays in place all day without smudging, even in humid weather. I also love that it's waterproof and holds up well through long days. The lash-boosting complex is a nice bonus, and it hasn’t irritated my sensitive eyes at all. It's great to know it’s cruelty-free and vegan, which makes me feel even better about using it. The ultra black color gives a bold, dramatic look that really defines the eyes.

This product is a great value for the money, made of great quality, easy to use, soft applicator tip, great color, glides great, dries quickly, great look, doesn't flake, smudge-proof and waterproof! This is by far my new favorite liquid eyeliner! I highly recommend this product AND this brand!! (Plus, the packaging on this product is absolutely awesome too!)
