The full review.
The Peptide Lip Shape, which arrived in January 2025 with Tate McRae’s face attached, is Rhode’s answer to a question many beauty consumers didn’t know they were asking: what if a lip liner felt like a lip treatment?
Texture
On application, the pencil delivers on its promise of comfort. It glides across the lips with zero drag or tug — a sensation that’s closer to drawing with a soft pastel than lining with a traditional lip pencil. The color deposits evenly and blends with minimal effort, creating a wash of pigment that looks like your natural lip color turned up half a notch. The boron nitride finish is the real star: lips look subtly contoured and defined without any visible liner edge, which is a neat trick for a product that is, technically, a liner.
Scent

Packaging
The built-in silicone smudger on the opposite end of the pencil is a nice concept that doesn’t quite deliver in practice. It’s meant to soften and diffuse the liner edge, but the silicone tip tends to push product around rather than seamlessly blend it. Most users — and most beauty editors who reviewed this — report better results from simply using a fingertip. It’s not a dealbreaker, but it feels like a design feature that looked better in the product development meeting than it performs on actual lips.
Common Praise
The Peptide Lip Shape is wonderful to wear. It’s comfortable, hydrating, and creates a beautiful soft-focus effect.
Common Complaints
But it does not last. Expect two to four hours of wear before significant fading, with the center of the lips being the first casualty while color stubbornly lingers at the lip line edges — creating a reverse-liner effect that’s the opposite of what you want. Eating, drinking, or any activity involving your mouth accelerates the decline. For a product that costs $24 and positions itself as a liner, the longevity simply doesn’t compete with traditional long-wear formulas.
Best for
If your liner philosophy is “I’d rather reapply something comfortable than suffer through something that stays,” this product was made for you.
Not ideal for
If you need your lip color to survive a workday without maintenance, you’ll find this frustrating regardless of how lovely it feels going on.
Works for
Rhode’s Peptide Lip Shape succeeds as an experience product. The application is satisfying, the finish is beautiful, and the comfort level sets a new standard for what a lip liner can feel like.

Skin match.
The science.
The Science
The Peptide Lip Shape uses two skincare-focused ingredients: Palmitoyl Tripeptide-1 and Trigonella foenum-graecum (fenugreek) seed extract.
Palmitoyl Tripeptide-1 is a Matrixyl family lipopeptide that stimulates collagen synthesis by mimicking collagen fragments. Research shows it activates fibroblasts and increases collagen types I and III. However, most evidence comes from facial skin applications at specific concentrations. No studies specifically test its efficacy in a lip cosmetic applied intermittently for a few hours. The lip's thin epithelium might allow better peptide penetration than thicker facial skin, but the benefit remains theoretical without specific delivery studies.
Trigonella foenum-graecum (fenugreek) seed extract contains diosgenin, a steroidal sapogenin studied for promoting cell proliferation and collagen synthesis. Some preliminary in vitro research suggests volumizing potential, but clinical evidence for topical lip application is limited. The extract also contains antioxidant flavonoids that condition the lips.
Boron nitride drives the formula's optical effects. This hexagonal mineral has a lamellar structure that scatters visible light across multiple planes to create a soft-focus effect on the lip surface. High-end photo-finishing powders use this same diffusion principle. Boron nitride achieves this without the occlusion or heavy feel of silicone-based blurring agents, which suits a lip product prioritizing breathability and comfort.
The formula architecture prioritizes slip and conditioning over adhesion. Caprylic/capric triglyceride and multiple ester emollients create a creamy glide, while the wax and polymer system provides minimal structure. This trade-off favors comfort over longevity; the formula does not bond to the lip surface like long-wear lip products.
Dermatologist Perspective
Dermatologists generally view the Peptide Lip Shape as a well-formulated, low-irritation lip color product. Board-certified dermatologists value the fragrance-free formula and the lack of common lip irritants like camphor, menthol, or phenol, making it suitable for patients with sensitive or reactive lip skin. The inclusion of Palmitoyl Tripeptide-1 and Trigonella foenum-graecum (fenugreek) seed extract is a positive but not transformative addition; these ingredients condition the lips but do not deliver clinical lip augmentation. Dermatologists note the emollient-rich formula helps patients with chronic lip dryness from certain medications, as it provides color without the drying effect of traditional matte liners.
Where it fits in your routine.
Twist up a small amount and line your natural lip edges. Fill the entire lip for full color or leave the center bare for a classic lined look. Use the built-in silicone smudger or a fingertip to blend and soften edges for a diffused finish. Layer the product to build coverage: one pass gives a sheer wash, while a second adds medium pigment. Top with Rhode Peptide Lip Tint, a gloss, or Peptide Lip Treatment for added dimension and longevity.
At $24 for 0.75g, the Peptide Lip Shape has a premium price for its size. But the formula quality—using peptide, fenugreek, and boron nitride—shows real formulation investment instead of just markup. The twist-up mechanism and built-in smudger add utility. For daily users who like the comfort and finish, the cost is about $6-8 per month. The $92 four-pack option saves $4, which is marginal. You pay for the wearing experience and skincare hybrid approach more than for product volume or long-wear performance.
Anyone who prioritizes comfort over longevity in their lip products. Ideal for the 'no-makeup makeup' enthusiast who wants naturally defined, contoured lips without visible liner edges. Perfect for beginners who want a forgiving, blendable lip color that's hard to apply badly.
Choose this if you need long-wear lip color that lasts through meals and a full workday without reapplication. Avoid this if you want precise, sharp lip definition for dramatic looks; the chunky tip and soft formula do not do that. Shoppers with deeper skin tones should swatch in person, because lighter shades may look ashy.
Product details.
Soft and creamy, it glides on like a crayon. The texture is more like a lipstick in pencil form than a traditional waxy lip liner. It feels hydrating and comfortable on the lips and does not create visible dry lines.
Fragrance-free with no noticeable scent.
Slim twist-up pencil with retractable mechanism — no sharpening required. The opposite end features a built-in silicone smudger for blending and softening the lip line. Follows Rhode's signature minimalist aesthetic. Available in 11 shades with a fitness/movement-inspired naming convention.
The first application feels satisfying. The pencil glides without tugging and deposits soft, blendable color. Boron nitride creates an instant blurred effect for natural lip definition. It causes no irritation, tingling, or adjustment period. The color is buildable; apply light layers to reach your desired intensity.

The backstory.
Rhode's entry into color cosmetics came with the Peptide Lip Shape in January 2025, launched with a campaign featuring pop star Tate McRae. The product represented Rhode's philosophy that makeup and skincare shouldn't be separate categories — every product should treat while it performs. The 11-shade range was designed around universally flattering neutrals inspired by natural lip tones, with a fitness-themed naming convention that nods to Hailey Bieber's wellness lifestyle.

Common myths.
A lip liner with peptides will visibly plump your lips
Palmitoyl Tripeptide-1 and fenugreek extract appear in small amounts in a product worn for hours, not 24/7. Any plumping benefit is marginal and gradual. The real value is a comfortable, hydrating liner — the peptides are a bonus, not a lip filler alternative.
This replaces the need for a lip liner and a lipstick
It works as a full lip color, but short wear time makes it better as a liner or base layer. Most users pair it with a gloss or lip treatment for a complete, lasting look.
FAQ.
What shade of Rhode Peptide Lip Shape should I get?
Rhode has 11 shades, from Lift (lightest neutral pink) to Move (deepest cool brown). Pick a shade close to your natural lip color for a natural 'my lips but better' look. Lift, Press, or Bend suit lighter skin tones. Lunge, Twist, or Balance work for medium skin tones. Lean, Stretch, Flex, Spin, or Move pair well with deeper skin tones.
How long does Rhode Peptide Lip Shape last on lips?
Expect 2-4 hours of wear before significant fading. The center of the lips fades first, but color stays at the edges. Eating and drinking accelerate fading. This is not a long-wear formula; it trades longevity for comfort and hydration. The twist-up mechanism makes reapplication easy.
Can Rhode Peptide Lip Shape be used as a full lip color?
Yes — the thick, buildable formula works as a standalone lip color for a soft, diffused look. Apply in layers for more intensity. For a longer-lasting full lip, most users pair it with a gloss or lip treatment on top. The formula prioritizes comfort, so it lacks the staying power of a traditional matte lipstick.
Is the built-in smudger on Rhode Lip Shape useful?
Opinions vary. The silicone smudger on the opposite end blends and softens the lip line for a diffused effect. Some users find it convenient for on-the-go touch-ups, but many reviewers say blending with a fingertip gives a better, more natural result.
Is Rhode Peptide Lip Shape pregnancy safe?
Yes — the formula lacks retinoids, salicylic acid, or other ingredients flagged during pregnancy. The peptide, fenugreek extract, vitamin E, and mineral pigments are safe for pregnancy. Lactic acid is in trace amounts as a texture agent, not an active exfoliant.
