Snoop's Take

Physicians Formula Eye Booster Super Slim Liquid Eyeliner is a precision liquid liner designed to deliver ultra-black, waterproof performance while also nurturing lashes with its unique Lash-Boosting Complex. It promises versatile looks ranging from delicate everyday lines to bold, dramatic wings in just a few effortless strokes. Community feedback is as sharp as the brush tip itself—with many users exclaiming, “The brush is my absolute favorite; it does exactly what I want it to and puts liner exactly where I want it,” while others laud its ability to withstand emotional moments (yes, even crying at weddings). Despite high praise for its pigmentation and precision, dissenters note concerns such as uneven pigmentation and a formula that can get a bit gummy over time. Overall, the chatter oscillates between ardent recommendation and cautious critique. Bottom-line: This eyeliner is generally recommended for its standout precision and waterproof formulation, though potential buyers should be aware of occasional inconsistencies that have sparked debate among its users.

What it does well!

Key strengths users can’t stop talking about.
Favorite brush tip for precise application
The brush is my absolute favorite; it does exactly what I want it to and puts liner exactly where I want it.
Super black doesn’t rub etc.
Always black and never smudgy
Always black, never smudgy, and the micro tip makes it really easy for me.
High-end feel for a drugstore product
One of the few drugstore products I have that feels high end.
Easy to achieve sharp winged eyeliner
it bleeds like crazy when I apply it, so no matter how sharp my wing is, it ends up looking fuzzy.
Good performance in crying situations
Made it through crying at a wedding. :)
Preferred brush tip for control
I also greatly prefer the brush tip pen liner over felt, I have more even control.
Solid recommendation for brown version
the physicians formula liner in brown is pretty good!
Highly pigmented compared to premium brands
it’s blacker than a lot of premium brands.
Effective even in humid conditions
I’m a hardcore “this is the only liquid liner I like” person and I haven’t had that problem when I switched to the waterproof (damn humidity!!).
Considered a holy grail liquid eyeliner
physicians formula DOES make my holy grail liquid eyeliner tho, it’s one of the ones with a little like, jar and a long handled brush.
Nice color and formula in non-waterproof version
This is only water proof in a different universe where the laws of physics are different.
Favorite eyeliner for ease of use
Easiest Liquid Liner I’ve Ever Used!!
it’s my fave!
Highly recommended for its appearance
Holy crap I am going to go buy some of that tomorrow lol your eyeliner looks great!
Rich color and precision
This was my favorite liner because of it's rich color and precision.
Favorite for ease of use and precision
Best/Worst of Physicians Formula. After giving them up 2 years ago, I recently found out they're cru
I love how thin and precise of a line you can get with it.
That shit doesn't budge, and I've found it very easy to work with.
Only one or two swipes needed to get it to the right black!
Effective when stored upside down
I definitely second the suggestion to store it upside down.
Highly recommended for felt-tipped eyeliner
I bought their felt-tipped eyeliner and swear by it, it's incredible as a liner.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Inconsistent pigmentation in some batches
Definitely no way close to brown.
I usually don't have to shake a liner for THAT long for it to come out pigmented.
Concerns about cruelty-free status
Since they're not cruelty free anymore :/.
Boo!
Sheer gray color and poor flow
Oh my god I hate this eyeliner so much. The "ink" is totally sheer gray, IF I can get any out at all!
Worst eyeliner resulted in a return
it was the worst eyeliner I had ever used. One of the only makeup products I have ever returned.
Inconsistent ink flow after a few uses
usually on my third use, i find it to become kind of patchy and the ink doesn't flow through as well.
It's like the brush gets gummy.
Can appear watery and requires multiple applications
It actually tends to come out kind of watery black over my eyeshadow and it takes multiple applications for me to get it really dark :/
Can ball up if layered too much
i do love it as a pretty good dupe for tattoo liner but i find that it kind of balls up if you go over it more than once to create a super dark line.
Potential confusion between black and ultra black
Is it possible you got 'black' and not 'ultra black'? I've heard there's a real difference.
Quality decrease reported in the new formula
I think they changed the formula!
That's a huge quality decrease.
the pigmentation is significantly weaker in the newer version.
This is the first liquid eyeliner that I planned on repurchasing.

Core Power Plays

The specs and strengths that make it shine.
Discussion about preferences for brown eyeliners
i find that the brown formula isn’t as good as the black in many brands.
Clinique's brown liquid liner to the reject list; it's way too light.
Storing eyeliner tip down may improve performance
remember to store it tip down in like a cup!
Holy shit that never even crossed my mind to store it like that.
Yay! Simple solutions!
Discussion about lash fiber technology
A little feathery, but they look pretty darn close to real lashes that just happen to be luscious.
it's interesting how different techniques and products work.
Discussion about changes in eyeliner formula
Which is the new and which is the old formula in the picture?

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Suggestions for alternatives to liquid eyeliner
I personally find it wears much better and it's a lot more comfortable bc it's flexible and "soft" even when set vs pen formulas which feel dry and usually end up flaking on me.
Using water to unclog the brush tip
Sounds stupid but it worked for me!

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Comparison to other brands
I had to finally call it and go back to Stila. Nothing I tried could even compare.
I really like the Anastasia liquid liner!
I used Lancôme artliner for years which was pretty good.
Comparison to drugstore eyeliners
It has really good staying power for my super oily eyelids, but it seems to move out the way if I try to do another line or put anything on top.
Wet and wild breakup proof liner
The waterproof liquid eyeliner from essence is good.
Comparison with other brands' eyeliners
I like NYX epic ink liner but the last two I bought leaked badly.
Both are comparable to Physician's Formula I would say!
I like it better than NYX Epic Ink and Stila Stay All Day.
The formula drys faster than others I've tried which is good to help prevent feathering.
Discussion about similar gel eyeliner alternatives
I used to love this formula, it was almost like a whipped texture and went on so easily.
I loooooove them. But seriously, PF, bring these back.
I like tons of their other stuff already.
It is tenacious and looks as good at the end of the day as when you first put it on.
User experiences with different eyeliner versions
It's straight up brown. I'm going to return it.
Seeking alternatives to Physicians Formula eyeliner
Essence is cruelty free & has a great one! Super last eyeliner & it is cheap!
I guess that’s good for wear but I hate having to mess with my eyes so much trying to remove it.
Alternatives to Physicians Formula eyeliner
Jesse's girl eyeliner. I buy it at Rite Aid.
Elf eyeliner is unbelievable.
Wet n Wild felt tip eyeliner is incredible for like $3!!!
General thoughts on other Physicians Formula products
Best by far I've tried is their Butter Bronzer. It SMELLS AMAZING! Like pina coladas and coconuts and sunscreen.
I second the Butter Bronzer; it honestly lives up to the hype.
Discussion about discounting of Physicians Formula products at CVS
I'm a fan. (Mostly because I always get them for cheap at CVS, but I've really fallen in love with their mineral makeup.)

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Discussion about potential clogging issues
I remember being told that when a product picks itself back up like that, it's because there's too much oil on your skin and the product can't grab on.
