Selena Gomez knows her way around an Instagram carousel. The 33-year-old actress regularly shares maxed-out, 20-slide posts, most recently dropping a 16-photo roundup for her more than 400 million followers. Among the soft, springy snapshots, one stood out: Gomez sitting outside in a black sports bra, wearing the mega-viral Medicube PDRN Pink Collagen Gel Mask ($19 for four).
In the rare case you’re new to Medicube, it’s a K-beauty skin-care brand founded in 2016, with a product lineup that’s earned a loyal following among beauty editors, influencers and celebrities alike. The pink gel mask Gomez uses, in particular, has thousands of reviews and a 4.6-star rating on Amazon.
As for what’s inside, the mask leans on line-smoothing humectants, including glycerin and soothing panthenol—ingredients that deliver an immediate plumping effect. For longer-term results, it’s packed with repairing salmon DNA (listed as sodium DNA), niacinamide and firming peptides, which require consistent use over time to make a visible difference.
With mostly five-star reviews, the mask has plenty of fans beyond Gomez. Reviewers praise everything from the user-friendly design to the glow it leaves behind. One of its standout features: it starts pink and turns transparent as your skin absorbs the ingredients, usually after three to four hours. You can apply it at the end of your skin-care routine and leave it on overnight, or wear it during the day while you binge a show or work from home—and maybe post about it, like Gomez.
