Who is the Degree commercial actress? Discover why Love Island star Leah Kateb is the perfect face for the ‘Five Types of Sweat’ campaign and how the ‘Leah Kateb Effect’ represents the latest evolution in modern advertising.
If you have seen the latest Degree commercial, you likely felt like you were watching an old friend giving you some sincere advice. The protagonist appears in an everyday situation common to us all—standing in front of the mirror in the morning, reaching for her deodorant. She looks directly into the camera as if speaking to us personally, testing the product in real-time and sharing the results of her “research.”
Many recognized her immediately: the actress, whose name is clearly displayed at the start of the video, is Leah Kateb, the breakout star of Love Island USA Season 6. In this Degree commercial, Leah doesn’t just lend her face to the brand; she takes on the role of an official “tester.” This choice invites us to reflect on the nature of the “Leah Kateb Effect”: that feeling of closeness she projects and why her choices regarding products, fashion, and beauty have become a “holy grail” for millions of followers.
Today, we explore why this effect is the perfect match for Degree.
Who is Leah Kateb, the Degree Commercial Actress?
For those who haven’t followed the pop culture headlines of the past year, Leah Kateb is much more than just a model. Born into a family of Persian origins, Leah shot to global fame as the central protagonist of Love Island USA Season 6. Dubbed the “Persian Princess” by her fans, she managed to transform a reality TV stint into a career as a legitimate trendsetter.
With millions of followers on TikTok and Instagram, she is now one of the most influential figures in fashion and beauty. Her “Get Ready With Me” (GRWM) videos—where she showcases her makeup routines and outfits with disarming sincerity—have become mandatory viewing for a community that hangs on her every word.
Upon the release of the Degree commercial, Leah Kateb shared a playful post that quickly went viral: “A hot (and fresh smelling) new bombshell just entered the Degree Clinical Villa❤️🔥” she wrote on Instagram, showcasing a communication style that makes her feel like a best friend capable of inspiring anyone.
It is this blend of sophisticated aesthetics and relatable everyday life that fuels her appeal, making her the perfect bridge between the polished world of high fashion and the authentic (and often chaotic) reality of daily life.
From GRWM to the Screen: The Psychology of the “Curator”
The element that makes Leah Kateb so effective as the actress in the Degree commercial is the narrative continuity with her social media presence. For her followers, Leah isn’t just someone they saw on TV; she is a voice that shares daily tips on mascara, vintage finds, and skincare. When she speaks to the camera while using a hairdryer or doing yoga in the ad, she is replicating the exact visual and communicative language of her most successful videos.
Psychologically, this breaks down the audience’s resistance to traditional advertising. We don’t perceive Leah as an actress reciting a script, but as an expert adding a new chapter to her beauty routine. Degree’s choice to show her in high-pressure situations—like a stressful interview—links directly to her Love Island experience. The audience watched her “sweat” (both literally and metaphorically) under the 24/7 gaze of cameras, making her product test feel entirely credible.
The “Leah Kateb Effect”: Why Do We Follow Her Choices?
The reason Leah’s choices are so influential lies in her rejection of static perfection. Leah built her following by showing the “process”: she applies makeup while chatting, does groceries with us, makes mistakes, laughs at herself, and allows herself to be vulnerable.
Her career is built on total transparency (epitomized by her famous motto, “Spare me!”), which makes her the most believable person to test something as intimate as a deodorant under pressure. This creates a bond of “Peer Validation”: we follow her not because we want to be exactly like her, but because we feel she is like us.
In the “Five Types of Sweat” spot, this dynamic becomes the identifying element of the campaign. Leah doesn’t just tell us the product is good; she asks us to watch while she puts it to the test. In doing so, the deodorant stops being a chemical object and becomes a survival tool for “Main Character Energy.”
For this commercial, Degree understood that to reach Gen Z and Millennials, you don’t need a perfect actress—you need a familiar face that can handle daily chaos with irony and honesty.
The Influencer Generation at the Service of Advertising
The inclusion of social media stars in national advertising campaigns is becoming increasingly common. We have seen several similar cases recently, from Amanda McCants for Old Navy and Druski’s comedic presence in T-Mobile spots to the viral Dr. Pepper jingle created by Romeo Bingham. The Degree commercial featuring Leah Kateb is in direct continuity with this clear trend: brands are no longer seeking just beauty, but a familiar narrative.
The fact that Leah also serves as the CCO of the Skylar perfume confirms that her “closeness” to the public has become a powerful commercial asset. In the Degree commercial, she isn’t playing an actress: she is our most expert friend who, between a yoga session and a professional challenge, confirms that we can stay in control. And because we are used to trusting her advice on social media, we believe her.
Navigating the stress of an interview or the heat of a hairdryer is the perfect metaphor for Leah’s journey: a girl who moved from anonymity to the center of a global media cyclone, managing to keep her cool (and her freshness) even in the “hottest” moments.
