Kourtney Kardashian reveals that ‘a stamp with tiny needles’ is the secret to her youthful skin

Kourtney Kardashian is letting slip the secret to her youthful skin.

The 41-year-old Keeping Up With the Kardashians star shared an attention-grabbing gold metal bikini selfie to Instagram to tell fans about her latest beauty must-have on Tuesday.

For the last several months, Kourtney has been amping up her skins collagen production with the help of  ‘a stamp with tiny needles’ similar to the celebrity favorite microneedling treatments.

On social media, the mother of three posed in a eye-popping gold mesh metal bikini with a matching neckerchief in the same material.

Kourtney – who was infamously dubbed by sister Kim as the ‘least interesting to look at’ among their familial bevy of beauties – stunned with her glowing skin, taught tummy, perk cleavage and extra-long wavy hair.

The reality star held up a small item, about the size of a tube of mascara, in the images and explained that the skin tool was the secret to her ageless look. 

‘Last April when we were all home with not much to do, I discovered this skin tool, a stamp with tiny needles,’ she explained in the caption. ‘It comes with a serum that pours into the stamp, which infuses it deeper into your skin since stamping is a form of microneedling.’

‘After my mom and Khloé were raving about my glowing skin over FaceTime, it instantly became one of my absolute favorite skin tools and product combinations,’ Kourt continued, adding that her company, Poosh, has partnered with the Things We Do med-spa on stamp of their own.

Her custom ‘vegan skin brew’ which was developed along with the popular L.A. based med-spa comes with the stamper and is sold on her website. A four month ‘ritual set’ retails for $225.

In addition to taking meticulous care of her skin, Kourtney also spends a lot of time focusing on her figure.

She recently showcased an aerial Pilates session on her Instagram stories, which demonstrated exactly how the mother of three maintains her killer bikini body. 

It seems that Kourtney also has a new man in her life as she has been spending time with longtime friend and Blink-182 drummer Travis Barker.

Much to his delight, she loaded up on the bikini content as he continued to post flirty comments on her posts including ‘yessss’ when she shared a snap and said ‘orange you glad I’m still posting trip pics?’

Fans first started to speculate the two may be an item about a month ago when she posted a photo of his favorite movie on Instagram and he began to appear in her comments section.

From there things continued to heat up as they spent the weekend together in Palm Springs both posting content from Kris Jenner’s pool.
