Stephanie Nicole, a beauty blogger, just posted a video to her YouTube channel revealing that the Kylie Lip Kit and Colourpop Cosmetics Ultra Matte Liquid Lipsticks have almost identical formulas.

Recently, the formula for the Kylie Lip Kit changed. Nicole decided to compare the two products to see if the second formula stood up to the original.

While she found the quality of Kylie's new formula to be just slightly lower, the color of the new formulation — which is listed as the same product on Kylie's website — is also different.

On a hunch, Nicole investigated to compare the ingredients of the Kylie Lip Kit to Colourpop's Ultra Matte Liquid Lipstick, which is frequently listed as a dupe for Kylie's product. Nicole found that the ingredients are just about identical.

After taxes and shipping, the Colourpop product is more than $23 less than Kylie's product.

For comparison, here's Candy K from the Kylie Lip Kit.

And here's Colourpop Ultra Matte Liquid Lipstick in the shade Clueless.

In the past, Jenner has addressed allegations that her lip kits have the same formula as Colourpop's product.

Meanwhile, the manufacturer Seed Beauty has Colourpop and Kylie Cosmetics both listed on its homepage. Both are suspiciously classified as "Confidential 1" and "Confidential 2."

Seed Beauty is owned by Laura and John Nelson, sister and brother business partners.

Laura and John Nelson also happen to be the founders of none other than Colourpop Cosmetics.
