Physicians Formula Ultra-Fine Liquid Eyeliner, PF10683 Black, 0.016 fl oz (0.5 ml)

The formula is long-lasting, waterproof, and smudge-proof. The product is hypoallergenic, fragrance-free, paraben-free, and gluten-free. It is also dermatologist-approved and clinically tested.

The scent of it is so good, the ingredient quality is amazing and it doesn’t smudge its packaging is so good and looks very nice and the r application is nice

Obtained similar results from some other liquid eyeliners but they took much longer to apply. There is plenty of pigment and it stays put all day. Also appreciated that it didn't irritate my skin or eyes.

Too light. I like a black matte eyeliner. This is very light, it goes on gray and sort of "watery."

Excellent product that goes on so smooth and creates incredible wings!! Physicians formula makes the best makeup, in my opinion. Great product for an even better price! Get out your coupons! Eyes on fleek!

All that money, trying to buy a good product and this didn't even last a week. It is all dry. I don't use that much and I am not to the extreme. Just little bit of ends. I am very disappointed. I don't even have the receipt anymore to return it.

This is one of my favourite eyeliners because I could always get the sharpest lines and my wing came out fierce everytime. It stayed on and no smudging. The packing is sleek and better quality ingredients for the price. Would recommend

This is a great eyeliner! The brush tip is smooth and easy to glide. The black pigment is strong and the formula is budge proof. One of the best ones out there!

So precise, easy to make the perfect wing, does not dry out easily, and affordable! The serum is a boost! The color is also pigmented. I will say it’s not very water proof though.

This is so pigmented! it does not dry out when using it on top of eyeshadows, it doesn't skip. It glides very smoothly and it doesn't look dried out at all, like when the look all matte and "cracked". My favorite so far and very long lasting.

I have been using this eyeliner for quite a while, I think it has one of the best aplicator point, it is like a brush pen, the point is super fine and it can create a very fine line with precision as well as thicker lines, the formula is confortable to wear, highly recommend! I will buy again.

My absolute favorite eyeliner! I'm not sure about the boosting abilities but I like how easily it glides on my eyelid and it stays on all day

After years of swearing by my Stila eyeliner, I’ve finally found a new (and cheaper!) holy grail liquid eyeliner pen! I keep this in black and brown and love the all day wear, especially for my eye shape.

It’s the best eyeliner I’ve ever tried. It is easy to apply, easy to take off… I have no complaints, other than sometimes I want it a little more black.. but I am using the black one, not the ultra black one.. so there’s that

Easy to use, does not crumble, resistant for the whole day. Even if the brush dries out a little, it is worth removing the film from it and the eyeliner as good as new. it is very convenient to draw arrows with a silicone brush! And it lasts for a very long time.

This is definitely a good liquid eyeliner. It stays put all day and is very black. I don't really use liquid eyeliner anymore, preferring the softer look of eyeshadow as eyeliner around my eyes, but back when I used eyeliner more frequently, I really enjoyed the physicians formula pen.

This is one of the best eyeliners I've ever used. I have hooded eyelids, and always had a problem with my eyeliner smudging when I closed/opened my eyes. This dries so quickly and doesn't disappear. This one is not the waterproof version, but it stays put and holds up against tears, smudging, etc.

This eyeliner is my new favorite drugstore eyeliner. Although I have not tried wearing this in the hot humid GA Summer weather, I have worn this for all day and evening work events. Thankfully it has not feathered,flaked, and bled down my face. I love easily it glides across my lash line, and that it has a fine tip, which allows me to draw light or heavy lines. I also like how it does not clump up my lashes if and when some get onto my lashes when I apply the liner. I have not noticed any length or growth to my lashes from the serum, but I have noticed that when the gets into my eyes from me applying too close to the lashline, it does not irritate my sensitive eyes. To remove, I do suggest using a waterproof eyemakeup remover and then use your normal face cleanser.

Last a very long time. Easy to apply. Doesn’t smudge or make a mess. Like the color a lot. Can’t go wrong with this drugstore eye liner. Does make a smooth appliance.

My favorite liquid liner! I have been using this for nearly 8 years and have been through countless tubes. I have hooded eyes and small real estate on my eyelids, so it is very important to me to have a very precise and fine line. This liner has a tiny brush tip that lets me lay color as close to the lash line as possible. Even with unsteady hands I feel that the brush tip isn’t so long that it bends and flexes too much - I have enough control. I don’t think it actually does anything for my lashes, but I am ok with that.
