Kourtney Kardashian's Stamp

According to her recent social media posts, the clean beauty advocate revealed her secret to achieving glowing skin.

She mentioned that she uses a beauty tool that involves "a stamp with tiny needles," similar to the microneedling technique.

"Last April, when we were all home with not much to do, I discovered this skin tool, a stamp with tiny needles. It comes with a serum that pours into the stamp, which infuses it deeper into your skin since stamping is a form of microneedling," Kourtney Kardashian's Instagram reads.

Moreover, she also cited how the famous momager, Kris Jenner, and her sister, Khloe, have been "raving" about her flawless skin, and with that, this has been her go-to beauty tool alongside her favorite skincare products.

She then concluded her post by greeting her 110 million followers by saying, "HAPPY STAMPING!!" while donning a tiny gold swimwear that perfectly suits well with her skin tone.

Friends and fans can't help but react to the reality star's flawless skin and, not to mention her famous curves.

Marketing executive Simon Huck pointed out how Kourtney Kardashian's skincare tools are always the bomb.

"You always have the best skincare gadgets," he wrote, while Australian model Shanina Shaik commented, "Yess!" followed by a heart and fire emoji.

Kourtney Kardashian Swears by the Benefits of Microneedling

There's no denying that Kourtney Kardashian wants the best and healthiest for her and her kids regarding wellness and beauty.

This is also the main reason why she launched her multimedia lifestyle platform called Poosh.

Interestingly, her brand is named after her eldest daughter, Penelope, whose nickname is Poosh.

On her brand's website, it pointed out the benefits of microneedling and its glow-giving effect on the skin.

It cited that this beauty procedure uses "fine needles to gently puncture the top layer of your skin," and with that, it signals the body that it needs to heal those micro-wounds. As a result, it produces more collagen into the skin.

Moreover, Poosh also introduced "The Things We Do Ritual Set," which retails for $225.

It features the Dew & Go Microneedling Stamp that Kourtney Kardashian has been using for months, alongside four ampoules of Brighten Skin Brew.

The vegan skin brew contains niacinamide and licorice root. As we all know, niacinamide reduces skin inflammation, eliminates oil, and minimizes pore appearance.

During her Harper's Bazaar Go To Bed With Me video, she shared her eight-step nighttime skincare routine, which involves doing microneedling.
