Review: Great colour great performance great wearability easy to remove. . - 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.
Review: My all-time FAVORITE liquid eyeliner!! - I ended up buying this Physicians Formula Lash Enhancing Eyeliner because I was in the market for a new liquid eyeliner and liked the idea of improving my eyelashes in the process. This is now the ONLY liquid eyeliner that I use! The price is excellent, and when I started using this it was only available online but now I'm seeing it in pharmacies so it's pretty accessible. The black pigment goes on dark and mostly matte (there can be a little bit of a gloss look to it so I wouldn't say it's completely matte). The felt tip is flexible and does a great job painting on with precision, both thick lines and thin lines (I like a cat-eye look, so this is important for me). It puts out the perfect amount of liquid liner and NEVER spills/leaks like some other brands do. This dries quickly, it's easy enough to remove if you make a mistake, but also stays on all day without smudging or flaking off. I am pretty picky about liquid liners but this product has worked SO well for me that I have been using it for years now. I honestly don't see too much of a difference in the length of my lashes, but I also don't apply my makeup every single day so maybe more consistent users will see the lash benefits. Overall, if you want a consistently good liquid eyeliner with the potential added benefit of lash growth, I HIGHLY recommend buying this product. Whenever I try to see what other eyeliners are out there, I'm always disappointed and come right back to this one. Hope this helps!

## Questions & Answers

**Q: Does the serum actually work, has anyone seen an increase in eyelash length?**
A: I have seen an increase in my lashes. This is the only eyeliner I was. It must be applied close to your lashes. I only put on top lid. I do believe my lashes have "hit" the max they will ever be.

**Q: Is this water resistant or waterproof. If you touch it does it leave ink on your fingers or under the eye? I do not want to look like a panda.**
A: It's def water resistant. My eyes water from allergies and it never budges or runs. It's the only eye liner that stays put on my eyes and I've tried many.

**Q: Is this one the brush tip applicator??**
A: It’s a very fine brush applicator tip.   Works really well!

**Q: Is this vegan-friendly?**
A: Not sure about vegan-friendly ingredients, but it is cruelty-free!

### ⭐⭐⭐⭐⭐ New fave!
*by A***L on July 4, 2024*

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.
