If there were a "most popular" award for skincare ingredients, "peptides" would surely make the podium. These short-chain amino acids are seemingly everywhere in moisturizers, eye creams, and other top-rated products thanks to their skin-repairing properties. And that characteristic makes them a go-to ingredient for lip treatments, too.
Shop the Best Peptide Lip Balms
"I recommend peptides to treat dry, chapped lips," says Ron Robinson, a cosmetic chemist and founder of skincare brand BeautyStat. Formulas containing peptides help not only moisturize dry lips but repair them too. "Our lips are thinner and have fewer layers of skin than the skin on the rest of our face," he says. "They do not have any sebaceous glands, so less sebum means they are more prone to drying out and chapping."
The question is, which peptide-packed formula should you try? Ahead, find a few of the best peptide lip balms, including picks from Robinson along with favorites from Bazaar beauty editors.

Robinson may be partial to this popular pick as he's the cosmetic chemist in residence for Rhode, but there's no denying the product's influence. "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.
- Number of shades: nine
- Key ingredients: shea butter, cupuaçu, babassu

Pros
- Has a plumping effect
Cons
- Pricey
"Not only are there so many shades of this peptide lip balm, but the cooling metal applicator feels like a trip to the spa on dry, chapped lips," says Bazaar beauty director Jenna Rosenstein. Robinson is a fan as well, saying "I love how this gently smoothes as it plumps the lips."

Pros
- Creamy and non-sticky
Cons
- Some reviewers don't like the strong scent
"Every time I try a new lip balm, I wonder how different this one could be from every other formula I’ve tried, but the Olehenriksen Pout Preserve quickly earned a prime spot in all of my bags," says Bazaar associate beauty editor Katie Intner. "The balm is very silky-yet-plush and hydrates the lips for hours, while many balms often perform a disappearing act an hour after you apply them." Although there is a range of shades and flavors, her favorite at the moment "is the Strawberry Sorbet Pout Preserve, made in collaboration with Anine Bing, that boasts a bronzy shimmery hue that can be worn day or night."
- Number of shades: five
- Key ingredients: kokum butter, mango seed butter, cloudberry oil
Customer review: "I bought this product and fell in love with it. I have every flavor, It smooths my lips and heals them when dry with ease. I love the creamy texture and the smell is nice as well." —Jillian P.
Pros
- Just the right amount of pigment
Cons
- Some reviewers noted the packaging can leak
If you prefer a gloss, Robinson recommends this moisturizing formula from Kosas, made with peptides and hydrating ingredients like hyaluronic acid. "I like its sheerness, but it also hydrates and plumps," says the cosmetic chemist.
- Number of shades: nine
- Key ingredients: hyaluronic acid, evening primrose oil, avocado oil
Customer review: "It's very pigmented and not uncomfortable or sticky. It does not dry my lips at all. The only thing is that you need to reapply it every few hours if you want more color, but even as it fades it leaves a nice color." —Sophie05

Pros
- Long-lasting
Cons
- The tube is on the small side at 0.25 oz
“This no-frills balm from Biba de Sousa is one of my favorite peptide lip balms of all time," says Bazaar associate beauty commerce editor Tiffany Dodson Davis. "A little goes a long way with its formula, which immediately sinks into my lips and keeps them hydrated for hours on end.”
- Number of shades: one
- Key ingredients: squalane, vegetable collagen, vitamin E
Customer review: "This is a great lip balm that creates a nice moisture barrier and makes my lips feel protected in dry weather. I like to use a lip scrub and then put this on to help with the healing process and for cellular turnover. It looks like a lip gloss but actually is very long-lasting and doesn't irritate my lips even when I wear it all day." —Anonymous
Best Exfoliating Balm
Eadem Le Chouchou Lip Softening Balm
Pros
- As shiny as a gloss but still deeply moisturizing
Cons
- Often out of stock
Smoothing, moisturizing, and plumping, this best-selling tube from Eadem does it all (in a sleek silver tube at that). The sheer, glossy shades are perfect to wear as your daily lip color, or if you want an unscented clear balm, go for the adorably named Butter Mochi.
- Number of shades: five
- Key ingredients: acai butter, African mongongo butter, moringa oil, lactic acid
Customer review: "Very moisturizing and smoothing on the lips. The texture is thick but not greasy. The color is pretty. Sheer to start but buildable." —Mary

Pros

What are the benefits of peptide lip balms?
As a reminder, "Peptides are short chains of amino acids," explains Robinson. "When applied topically, they can act like messengers by triggering cells to produce more collagen and elastin, and they can help soothe the lips as well as help repair skin’s barrier." As a bonus, "They can also help to visibly plump and reduce the look of lines around the lip area."
Can peptides plump lips?
It's true! "Yes, they can [plump lips] with continued use," explains Robinson. Even better, they do so without causing stinging or irritation, as some of the plumping formulas of the past were known to do.
