If there were an award for "most popular" skincare ingredients, peptides would undoubtedly be in the running. These short-chain amino acids are found in moisturizers, eye creams, and other highly rated products thanks to their exceptional skin-repairing properties. This makes them a go-to ingredient for lip treatments as well.

"I recommend peptides to treat dry, chapped lips," says Ron Robinson, cosmetic chemist and founder of BeautyStat. Peptide-infused formulas not only hydrate dry lips but also help repair them. "Our lips are thinner and have fewer layers of skin than the rest of our face," he explains. "They lack sebaceous glands, so without enough sebum, they’re more prone to drying out and chapping."

So, which peptide-rich lip balm should you choose? Ahead, we've rounded up some of the best peptide lip balms, featuring recommendations from Robinson as well as favorites from Bazaar's beauty editors.

"I love that it’s rich and balmy and the peptides help to plump," he says of the It lip treatment, which is now available in a limited edition cinnamon roll flavor, inspired by the treats founder Hailey Bieber bakes for friends.
