Kourtney Kardashian’s Lemme line is doing its first-ever collab — and naturally, sister Kylie Jenner was first in line.
The reality TV stars turned wellness and beauty moguls announced today that they’ve teamed up to launch limited-edition Lemme x Kylie Cosmetics Skin Glaze Gummies.
It’s the first time the oldest and youngest Kardashian-Jenner sisters have worked together in nearly a decade, and they marked the moment by recreating the iconic Sofia Loren and Jayne Mansfield photo in full vintage-glam.
The co-branded gummies, priced at $30, will be available exclusively at Ulta Beauty on Sunday, February 1, alongside the debut of Kylie Cosmetics’ new Pomegranate Lip Butter.
“Our Skin Glaze Gummies are uniquely formulated with a clinically-studied longevity molecule called spermidine, and with a pro-retinol vitamin complex shown to promote skin health, skin barrier integrity and the skin’s natural immune defense,” Kourtney told The Post.
“We’re obsessed with this next-level innovation and can’t wait for our community to try it.”
What is spermidine?
Spermidine is a natural compound found in all living organisms and belongs to a group of molecules called polyamines.
It plays a key role in cellular growth, repair, and longevity by supporting autophagy, the process where the body breaks down and recycles old cell parts to make way for newer, healthier ones.
Spermidine levels naturally decline with age, which can reduce autophagy, increase inflammation, and raise the risk of age-related health problems like cardiovascular disease, Alzheimer’s and metabolic dysfunction.
It also contributes to lower collagen, elastin, and lipid production, which can make skin thinner, sagging, and less elastic. Reduced spermidine may also weaken the skin’s ability to fight oxidative stress, accelerating wrinkles and slowing healing.
Fortunately, research suggests that consuming spermidine-rich foods like aged cheese, broccoli, wheat germ, and mushrooms, or taking supplements, may support healthy aging and even extend lifespan.
While human beauty studies are somewhat limited, one lab trial found that spermidine increased collagen and elastin production in aged human skin cells. It also boosted lipid-related gene expression, which supports the skin’s outer barrier to lock in moisture and keep irritants out.
In a follow-up test, applying a topical spermidine formulation improved skin elasticity and hydration after 28 days.
An added bonus: research suggests spermidine may also extend the hair growth phase and reduce shedding, in addition to supporting nail health.
It’s no wonder spermidine has earned the nickname “the youth molecule.”
Bite-sized beauty secrets
The Skin Glaze Gummies also contain pro-retinol and pro-collagen vitamins to further support skin health, all packed into a bite-sized gummy flavored with pomegranate, strawberry and tart cherry.
“This is the collab my skin has been waiting for,” Kylie said in a statement.
“Kourtney and I wanted to create something that makes your daily beauty routine feel like a treat. The Skin Glaze Gummies give you that lit-from-within radiance, and paired with my new juicy Pomegranate Lip Butter, it’s the perfect duo for a hydrated look.”
The Lip Butter is the latest drop in Kylie Cosmetics’ best-selling line, priced at $21, designed to hydrate and protect dry, chapped lips while delivering a glossy finish and a hint of sheer red color.
“This collaboration has been a long time coming,” Kourtney said. “Working with Kylie felt like the perfect way to blend beauty and wellness in a way that feels authentic to both of our brands.”
But you’ll want to move fast. The Skin Glaze Gummies are only available for a limited time in stores and online at Ulta.com.
