When She's Not Using Rhode, Hailey Bieber Uses *This* Kylie Jenner–Approved Lip Liner
Our take

The relentless churn of viral beauty trends can feel both exhilarating and exhausting. Just when we’ve fully embraced the glazed donut skin of the past year, a new obsession surfaces, fueled by the algorithms of TikTok and Instagram. The current fixation? Kylie Jenner’s preferred lip liner, now championed by Hailey Bieber, and rapidly ascending the ranks of “must-haves.” It’s a fascinating illustration of how celebrity endorsements, particularly within a tightly knit sphere of influence like this, can instantly catapult a product to cult status. The speed with which this has occurred underscores the power of micro-trends, and the discerning eye of the modern consumer who seeks validation from trusted sources. Consider, for example, the recent resurgence of ballet flats, a trend Kendall Jenner has actively embraced Take a Bow, Ballet Flats—Kendall Jenner Is Committed to Having a Flip-Flops Fall, mirroring a broader shift towards understated elegance and a rejection of maximalism. Similarly, the conversation surrounding AI's influence on creative industries – as explored in AI is changing what one person is capable of creating. I think the question now isn’t whether we use it, but HOW we use ... – highlights a parallel dynamic: the rapid adoption of new tools and the evolving understanding of their implications.
What makes this lip liner phenomenon particularly compelling is the subtle shift it represents within the beauty landscape. It’s not about dramatic transformations or overtly bold looks; it's about refinement and subtle enhancement. This aligns perfectly with the current mood, a desire for a polished, effortless aesthetic that prioritizes natural beauty. The fact that Bieber, a figure known for her understated style and “clean girl” beauty routine, is endorsing this product lends it an air of credibility and aspirational quality. It’s a testament to the power of suggestion, rather than overt promotion. This echoes a broader trend toward “skinimalism” and a focus on foundational products that enhance rather than mask. Even the emergence of skincare trends like "zombie cream," which promises a luminous glow “Zombie Cream” Wasn't on My 2026 Bingo Card, But It's Giving Me My Glowiest Skin Yet, demonstrates a continued interest in achieving healthy, radiant skin as the foundation for any makeup look. The lip liner, in this context, acts as a finishing touch, a subtle detail that elevates the overall aesthetic.
The speed of these trends also begs a question about longevity. While the hype surrounding this particular lip liner is undeniable, will it sustain itself beyond the initial viral moment? The beauty industry is notoriously fickle, and consumers are constantly seeking the next “it” product. The key to lasting relevance, it seems, lies not in fleeting trends but in products that genuinely deliver on their promises and align with a broader aesthetic philosophy. The subtle elegance associated with Bieber and Jenner’s styles suggests a potential for greater staying power than some of the more fleeting, experimental beauty trends we’ve seen in recent years. This isn't about chasing the latest fad; it’s about cultivating a sense of timelessness and quiet confidence, a sensibility that resonates deeply with a discerning audience.
Ultimately, the rise of this lip liner is a microcosm of the current beauty landscape: a space driven by celebrity influence, social media algorithms, and a growing desire for understated elegance. It speaks to a broader cultural shift toward authenticity and a rejection of performative beauty. The question now isn't simply about *what* products are trending, but *why* they're resonating so deeply with consumers. As we move forward, it will be fascinating to observe how these micro-trends evolve and whether they contribute to a more sustainable and authentic approach to beauty.

Rhode's Peptide Lip Shape launched back in January 2025 with a lot of internet fanfare. Since then, Hailey Bieber has used them in countless makeup tutorials and GRWM videos. It's only natural. She is Rhode's founder, after all... and the chief creative officer and head of innovation, if you want to get specific.
Recently, though, it's come to our attention that she often uses another lip product, and no, it's not Rhode. It's a certain lip liner from Kylie Cosmetics. Yep, the company helmed by her friend and fellow beauty-brand founder Kylie Jenner. We love to see friends supporting friends. Ahead, see the exact lip liner.
There are so many examples of Bieber using the Kylie Cosmetics lip liner. Here, she uses it at Coachella, aka Bieberchella. She's also used it in a recent TikTok GRWM and in a video detailing her go-to summer makeup routine. One thing is clear: She genuinely loves this lip liner.
Kylie Cosmetics Precision Pout Lip Liner

Much like Rhode's Peptide Lip Shape ($24), this product can sculpt, define, and contour the lips. It's a wooden pencil that can be blended out for a blurred lip or sharpened for a precise point. On that note, make sure you have the Kylie Cosmetics Pencil Sharpener ($6) handy.
Designed to create a fuller-looking pout, it has a waxy texture that grips the lips for long-lasting wear without too many touch-ups needed. The brand promises tug-free strokes, even color payoff, and a smudge- and feather-proof finish.
There are 14 shades in total, ranging from neutral to deep red, but Bieber uses Comes Naturally. The soft mauve looks strikingly similar to Rhode's Peptide Lip Shape in Press ($24), albeit slightly cooler in tone.
