I’ve been working on my under-eye blue circles for a few years now. Every time I get on top of them with a great skincare routine to erase dark circles, I forget to keep going with my routine then they make a comeback. Thanks, ADHD.

So it’s no surprise, then, that I have tried a lot of concealers to cover up under-eye discoloration and concealers to get rid of dark circles. And I’ve written a lot of reviews of concealers that get rid of dark circles. Here are my previous favorites, in case you are wondering.

A few weeks ago, I found a product that was so good, it actually covered up my tattoo in just two coats. The Urban Decay All-Nighter waterproof concealer. Staring at the empty space where my tattoo used to be, I was still skeptical. I’ve been hurt by concealers that cover everything but cake in my fine lines and age me about two decades in one fell swoop. So I tested it some more.

Let’s look at it in more detail.

The Urban Decay All-Nighter waterproof concealer comes in a silver tube the size of a mascara. It looks great in my handbag. And because it’s shiny, it’s easy to find, even in low lighting like when you’re trying to touch up your makeup in the car.

Not that you’ll need to do many touch ups with this one. Honestly, with the amount of actors having to do their own make up right now, this product will be flying off the shelves.

Onto the testing.

So I have this tattoo. It’s Hello Kitty. You might think it was a moment of drunk regret, but you’d be wrong. I got this tattoo when I was in Santa Barbara, California, and the only time I’ve ever wanted to get rid of it was when I was in Japan because you’re famously not allowed to use the hot baths if you have tattoos, even Hello Kitty tattoos, in case you’re a gang member.

At the time I used a different method to get it to vanish, which I’ll talk more about some other time. Today, I decided to see if this waterproof concealer would have worked.

First I painted over half of it with one coat of the Urban Decay All-Nighter waterproof concealer. As you can see, the heavy black lines have significantly faded away.

Interestingly, it actually conceals better in brighter light, as you can see in this photo with the flash on:

However, since I don’t live my life on a film set, I live in a world of natural light, it would still be obvious to anyone who looked at my wrist that there was a tattoo there. Only now it was a tattoo covered in makeup.

So I added a second coat. That changed things.

Now that’s what I call coverage. That’s in the same light as the first photo.

But wait. We haven’t tested two coats with the camera flash, yet.

Oh. My. God.

You would literally have to be 30cm away from my wrist to know there was a tattoo there in bright light.

Okay, great, it works to make the tattoo disappear. But how long does that last?

Before we answer that, you’ll notice I’m wearing a dress with white stripes, I can confirm there was no transfer of cosmetics onto dress. Literally none.

Okay, now let’s see how long it lasted.

Using the time signatures from my phone, you can see I finished the second coat of concealer at 3pm:

At 9pm, after about 6 hand washes, and doing the dishes, it was only looking a little faded, so it will give good coverage for at least 6 hours:

At 2am, it had faded a bit but was still giving phenomenal coverage:

“Ah,” you say, “But you said at the start of this review that testing it on a tattoo isn’t the same as testing it on your face.”

And you’d be right.

So I put it on my ugly mug and took some pictures. On one side, I put the Clio Kill Cushion Foundation SPF 50 PA++++ on top of my concealer. I left the other side bare except for the Urban Decay concealer.

I put it on at about 5pm and it gave pretty good coverage immediately (first photo is my face with no make-up):

And this was after applying the Urban Decay. On the right hand side of each picture, I put foundation over the top to see how this product would work with other make up, because let’s face it, few people wear just a concealer alone.

The coverage was so strong, and yet even up close, my face didn’t look made up, and there was no caking, it just looked so natural! If you get a good shade match for your skin, you could actually wear this concealer by itself.

To be honest I was quite busy that day so I didn’t get to check in again until 3am, at which point I’d lost my phone so I had to use my husband’s phone and get him to send the photos in a Facebook message. After 10 hours, his phone made it look like this, but I don’t know if his camera has some odd settings or isn’t HD or something like that because I didn’t feel that pretty when I looked in the mirror.

So because I wasn’t 100% sure of what I was seeing, I decided what the hey, let’s leave it on overnight and see what happened.

I woke up pretty late because I’m still breastfeeding a baby who demands milk every couple of hours and I’m coming off some medication I was taking for post-natal depression, and these things are conspiring to make me very, very sleepy right now. So it was 2:45pm when I got up and took a photo.

Seriously I was shocked.

For comparison, I washed my face and took another photo #nomakeupselfie and all my usual imperfections came back:

 

This apparently took ten minutes.

And this is what my pillow and eye mask looked like after sleeping in my make-up:

Guys the Urban Decay All-Nighter waterproof concealer is the real deal. 100%. If you can’t get rid of blue circles or want to know how to erase dark circles under eyes, this is the new best quick fix on the market. The best part? It’s waterproof and stays put for at least 12 hours. Even when you get it wet. There’s a huge range of shades and the bottom line is, it’s cheaper and better than Bobbi Brown’s concealer. And it looks better in your bag and doesn’t require you to buy a separate concealer brush.

Vertict: Holy grail product.

Get it here on Amazon if you’re in the UK and Ireland, or visit your local department store that stocks Urban Decay in the States.
