Next up in our series of products from Facebook ads that we see, purchase, and review is the Thrive Causemetics Infinity Waterproof Eyebrow Liner.

They claim it “holds like a wax, blends like a powder and intuitively adjusts to match your brows,” so how could I not try it? Especially considering I’ve been obsessed with my big fat Greek eyebrows since I was a child idolizing Brooke Shields, and I love the look of a fuller, well-groomed brow now.

The Infinity Waterproof Eyebrow Liner: Putting it to the test

You choose from three “universal” shades (with cute names too!), ranging from light blonde to black and each is supposed to blend with your natural eyebrow shade perfectly.

After reading the reviews, I decided to go with the middle shade called Audrey for dark blonde to medium brunette, despite the fact that my hair is a pretty dark brown.

The pros will tell you to stay within a shade or two of your hair color; but I’ve found that with very dark hair, unless you want to look like Groucho Marx, you should choose a brow color a bit lighter than your natural color.

Luckily, I was right. The Audrey color was perfect for me.

What’s different about the Infinity Waterproof Liner compared with typical brow pencils is that it has a very fine retractable tip.

On the plus side: no pencil sharpener needed!

On the downside: it won’t last as long as a traditional pencil, which can be sharpened. Those seemingly last forever.

So first, I used the spoolie brush on the other end to groom my brows before filling them in. Then…liner time.

Turns out the retractable pencil is so wonderfully thin, it’s really easy to fill in and shape your brows neatly and naturally; the result is more like the thinner hairs of your brow rather than a flat line of color.

And true to the very convincing sales pitch — as in, the one that made me finally buy the thing after seeing it a zillion times — the Infinity Waterproof Eyebrow Liner is indeed waxy enough to hold hairs in place, thanks to shea butter, but not so much that your brows look stiff and unnatural.

Take a look!

The Infinity Waterproof Eyebrow Liner: Bottom Line

If you prefer an eyebrow pencil over powders, the Thrive Causemetics Infinity Waterproof Eyebrow Liner is one of the best I’ve ever tried.

And I’ve tried dozens.

(Told you I was brow obsessed!)

The look is fantastic and natural, even while staying in place for the duration of the day. I’d normally need to use a brow gel, but unless your brows are really bushy and unruly, this liner eliminates that step. And because it’s waterproof, there was no smudging at all.

When the day is over, I also love that the liner comes off so easily using my regular face wash. No special remover needed.

On top of all that, the liner is cruelty-free, and paraben, sulfate, and latex-free, so if you prefer more natural products, that’s an added bonus.

As for the price, at $21, it’s on the higher end for eyebrow pencils, but because Thrive donates one product for each item purchased to a woman doing her best to thrive through cancer or domestic violence, spending a little more on it feels good.

And feeling good is beautiful.
