CosRx’s The 6 Peptide Skin Booster isn’t just about packing in as many peptides as possible—each peptide has a different job, from supporting elasticity and smoothing fine lines to calming skin and boosting radiance. The lightweight, toner-meets-serum formula also layers in niacinamide and adenosine for anyone chasing a bouncy, healthy glow. “I’m obsessed with the texture,” says Han. “I use this as my first step following cleansing, and I like that it’s not watery—more akin to a lightweight gel serum.”

Anua PDRN Collagen Glass Skin Trio

If your algorithm keeps insisting you try Anua’s PDRN Hyaluronic Acid Oil Capsule Mist, consider this your sign to follow through. Each spritz drenches skin in salmon-derived PDRN (a regenerative ingredient that supports skin repair, improves elasticity, and boosts radiance), plus hyaluronic acid and hydrolyzed collagen for an extra hit of hydration and bounce. “I spritz it on throughout the day on my dry, sensitive skin and use it with the Melting Patches for a DIY mask moment,” says Christa Joanna Lee, contributing commerce writer. “It definitely leaves skin looking damp, so I’d skip using it over makeup.” Follow with the cream afterward to seal it all in.

Medicube PDRN Pink Peptide Serum

We had a feeling PDRN wouldn’t make just one appearance in our K-beauty roundup. Medicube’s PDRN Pink Peptide Serum pairs it with niacinamide for brightening, adenosine and copper peptides for firmer-looking skin, and a mix of glycerin and sodium hyaluronate to keep skin plump and bouncy. “After a few uses, I could see that this was definitely contributing to more hydrated-looking skin, helping me achieve that dewy glow,” says Lauren Alberti, video producer.
