Physicians Formula Eye Booster, Lash-Enhancing 2-in-1 Eyeliner Serum, Dermatologist Approved, Hypoallergenic, Cruelty-Free & Vegan - Ultra Black

Very easy to apply, excellent staying power, very precise, great product !

My favorite eyeliner for winged eyes. I love the bristle, paintbrush type tip. You can really fine or thick lines with great accuracy. Glides on nicely and drives quickly with a bold color.

I wanted to try this because I have sensitive eyes and because it looked like it could make a 𝘳𝘦𝘢𝘭𝘭𝘺 fine line. For context, I’m almost 45. I’ve used many different brands of liquid eyeliner—Stila, KVD, Sephora, drugstore brands. I have been using Nyx for a long time now, but it can be a mixed bag—dried out and hard to get a nice line one time and a drippy mess another time (again, talking about Nyx). So I decided to give this a shot. The Physicians Formula 𝙙𝙤𝙚𝙨 make an amazingly fine line! It’s very black (opaque) and is smooth and easy to use. I do a cat eye every day, and it’s so much easier and faster with this! I wore it to work on a shorter day because I didn’t know how it would hold up. My days are packed with no breaks, so I didn’t want to take chances when I wouldn’t have a chance to check my face. It looked great when I glanced in the mirror as I was leaving work. Later in the evening, I was looking more closely in the mirror and I was very pleased to see that it had not cracked or flaked at all. I didn’t have as much smearing (almost none, but not zero) at my outer eye corners, which tends to happen by the time 5 or 6pm comes. That’s a big deal because I’ve been horrified before when I’ve looked in the mirror and it looked like I had been crying or that I’m an oily mess. I’ve also noticed that I haven’t had the black goo in my inner eye corners that I’ve had before with other brands. It’s nice that it’s supposed to condition the lashes! I’m only a week or two in now, so we will see on that, but everything else makes it my new fave.

TLDR: Pros: Suitable for sensitive eyes; doesn't cause itchiness or irritation. Good longevity; doesn't smudge, even in hot weather. Lovely dark brown color. Precise application thanks to the brush tip. Budget-friendly option. Cons: Tendency to crumble if touched, so not ideal for habitual eye-rubbers. Requires multiple coats for intense pigmentation. The pencil may dry out faster than expected, making it less cost-effective. Who Should Buy: Individuals with sensitive eyes looking for an eyeliner that won't irritate. Those seeking a long-lasting eyeliner for warm weather. Makeup enthusiasts who prefer a dark brown eyeliner. People who are patient and don't mind shaking the product before use. Shoppers on a budget who want a decent eyeliner option. Overall Rating: 3.5 out of 5 Hey there, fellow makeup enthusiasts! 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!

Very thin tip that is easy to apply and makes a very small line. That is how I like to wear my eyeliner. Seems to stay on throughout the workday pretty well. I was using Sephora and they quit making the very fine tip in their brand. Glad I found this. I do recommend.

I would normally give this eyeliner 5 stars. However, each time I purchase (which is numerous times) the tube only lasts about 3 weeks. Which is frustrating. This eyeliner is great! Its easy to apply and glides on. It’s the perfect dark brown color and washes off great. I just can’t afford to buy eyeliner every 3 weeks.

Wanted to try a brown liquid eyeliner I typically do go for clean formulas. I’m not sure if this is very clean. I know it’s for sensitive eyes, but I thought I’d just give it a try. this product is absolutely amazing. It works like a dream. I will follow up with a photo, and also will follow up how long it lasts. I’m not using it on a daily,but I’m very pleased with how easy it goes on how good it looks. The color is awesome and stays all day even through chiropractic appointments when my face is squished in that pillow, it’s not a flake, not a smudge and to come off even water takes it off even though I double cleanse every night this is highly recommended in the price point is inexpensive and it came really quick as far as it being a serum for eyelash growth. I have not noticed anything yet, but will follow up if I do that’s not why I bought this, but it was a nice bonus.

Love this eyeliner. It's the only kind of liner I will use. Great quality and goes on effortlessly. Totally smooth and mess free.

My favorite eyeliner ever!!!! It’s amazing and so easy to apply. I buy 6 at a time so I never run out

Muy delgado, dura todo el día y no explota cuando te lo llevas en avión (como el de NYX)

Lo compre por probar ya que el que uso generalmente no estaba disponible. Siendo más barato es mucho mejor, con mejor aplicación, más densidad del color y aguanta mejor. Volveré a comprar este.

Don’t mind my struggle to get the package open it was not as hard as I probably made it look. I really like the formula of the liquid, the feel on the skin, and the shape of the applicator. Was very easy to get a nice shape and a smooth line. The one thing is if I bought again I probably would by the true black rather than just the ‘black’ as this one is more of a charcoal or dark grey and I do like a really rich black.

Este delineador me encanta, es mi favorito. Lo uso desde hace mucho tiempo y es el mejor que he probado. El pigmento es muy bueno, la duración también y el plumón en sí también. Tenía un poco de miedo de comprarlo por Amazon porque no sabía si la calidad sería buena o no. Sin embargo si lo es, y lo recomiendo muchísimo.
