Hailey Bieber Uses This Product to Delete Dark Circles—Now I Do, Too

Here atBest Knockoff Luxury Clothing , we take our beauty recommendations very seriously. We know that makeup isn't a one-size-fits-all kind of thing, so even though a celebrity might swear by a certain product, we always make sure to test it out ourselves to see if it's worth the hype. So, this week I decided to put Hailey Bieber's favourite under-eye corrector, the Kosas Revealer Extra Bright Serum Powered Color Corrector, to the test to see if it would help with my pesky dark circles.

If you're not yet familiar with an under-eye corrector, this product is slightly different from your usual concealer. I like to think of it more as a dark circle treatment. Although it looks similar to an under-eye concealer, it comes in a range of colour-correcting tones that help to neutralise the shadows under your eyes.

The Kosas corrector is loved for its creamy formula, and Bieber herself praises its ability to add luminosity to your skin. As someone who is just getting over a nasty cold, my dark circles are looking particularly bad at the moment, so I thought it was the perfect time to put this product through its paces. Keep on scrolling to see how I got on.

The Formula

Like many Kosas products, this formula focuses on your skin health. It is packed with peptides and hydrating botanicals, so it's great if you suffer from dry skin like me. It has also been designed with sensitive skin in mind, so you don't have to worry about it irritating the delicate area around your eyes.

The creamy formula has a serum-like feel, and works to reduce discolouration and add radiance. You can use it by itself like Bieber likes to do, or you can layer it under your concealer for a more seamless finish.

The Shades

As mentioned, this product comes in a range of colour-correcting shades. There are five options on offer, from pink to deep red hues, depending on your skin tone. Bieber uses the shade "Magic", a very light pink, but I opted for "Illusion", which has a hint of peach to help neutralise the blue tones under my eyes.

The Application

Thanks to the creamy formula, this product is a dream to apply. I have struggled over the years to find a suitable under-eye corrector, as my skin is really dry, but this blended into my complexion in seconds and was practically undetectable. I like to use my ring finger or the Hourglass Vanish™ Seamless Finish Concealer Brush (£39) to pat the product into my skin for a natural look.

The Results

Honestly, I did not expect to love this product as much as I do. I have always suffered from blue discolouration around my eyes, and this under-eye corrector made it practically disappear. Even without concealer over the top, my under-eyes appeared brighter and more radiant. Believe it or not, even my boyfriend commented on how good my skin looked.

However, the thing I loved the most was just how creamy the formula was. I think under-eye correctors and concealers can be so hit or miss, as a lot of products can cling to dry skin (I sometimes need to use an eye cream first), but this created a smooth, hydrated base for the rest of my makeup look.

The only downside I experienced when testing this product was some creasing near the end of the day. I recommend using a small amount of product to start with, as using too much can definitely contribute to this. I also recommend setting the corrector (and your concealer) in place with powder, too. While this was a bit of a shame, as someone who has tested hundreds of makeup products over the years, I'm yet to find an under-eye corrector that is completely foolproof, and would happily overlook a little bit of creasing for the brightening effect that this gives.
