The New York City premiere of Big Mistakes marked a significant milestone for actress Rachel Sennott, who arrived at the event in a meticulously curated visual presentation that balanced high-fashion elegance with a contemporary, skincare-focused beauty approach. Working in close collaboration with renowned celebrity makeup artist Samantha Lau, Sennott debuted a look characterized by a "bronzed rose" smoky eye and highly sculpted, high-shine lips. The entire beauty application utilized products from Kosas, a brand known for its "clean beauty" ethos and the integration of active skincare ingredients into decorative cosmetics. This strategic partnership highlights the ongoing trend of celebrity red carpet appearances serving as sophisticated marketing platforms for beauty brands, where the performance of products under high-intensity flash photography and long-duration wear is put to a public test.
Contextual Background of the Big Mistakes Premiere
The New York premiere serves as the centerpiece of the domestic promotional tour for Big Mistakes, a project that further solidifies Rachel Sennott’s standing as a leading figure in the modern cinematic landscape. Following her breakout performances in independent hits like Shiva Baby and the satirical comedy Bottoms, Sennott has transitioned into a role that demands a heightened level of red carpet sophistication. The premiere, held at a high-profile Manhattan venue, saw Sennott wearing a Georges Chakra Couture gown, which provided a structured and dramatic backdrop for the warmth and luminosity of her makeup.
The collaboration with Samantha Lau is part of a broader strategy to refine Sennott’s public image. Lau, whose portfolio includes work with high-profile clients such as Dua Lipa and Whitney Peak, is recognized for her ability to create looks that appear effortless yet are technically complex. For the Big Mistakes event, the objective was to create a "glow-from-within" effect that complemented the avant-garde nature of the couture while maintaining an approachable, modern edge.
Technical Breakdown of the Beauty Application
The architectural foundation of the look was the skin. In modern red carpet beauty, the shift has moved away from heavy, matte "mask-like" foundations toward breathable, light-reflecting bases. Lau utilized the Kosas Revealer Skin-Improving Foundation SPF 25 in shade 180 Light Cool. This product is formulated with hyaluronic acid, niacinamide, and peptides, designed to improve the skin’s texture over time while providing immediate coverage. By selecting a cool-toned base, Lau was able to neutralize redness while allowing Sennott’s natural skin texture to remain visible, a hallmark of the "clean girl" aesthetic that has dominated the industry in recent years.
To achieve the necessary dimension for professional photography, Lau employed a multi-layered brightening strategy. The Revealer Extra Bright in Illusion was used alongside the Revealer Super Creamy + Brightening Concealer in shades 2.3N and 3.6C. These were applied strategically to the orbital area and the high planes of the face to create a lifting effect. The use of multiple concealer shades allows for a more natural transition between highlight and shadow, preventing the "flat" look that often occurs with single-shade application. To set the base without sacrificing the luminous finish, a light application of Cloud Set Setting Powder in Feathery was used, which utilizes baked technology to provide a soft-focus effect.
The Bronzed Rose Eye and Sculpting Techniques
The focal point of the makeup was the "bronzed rose" smoky eye, a color palette that offers a softer alternative to the traditional charcoal or black smoky eye. Lau utilized the Soulgazer Intensifying Gel Eyeliner in the shades Hypnotize and Allure to establish depth at the lash line. These gel-based formulas were blended outward to create a diffused, hazy perimeter.
To add the "rose" element and metallic dimension, the Shiny Objects Powder Highlighter in Glimmerose and Embered was applied directly to the lids. This technique of using highlighters as eyeshadows is a common industry practice to ensure maximum light reflection. The eye look was framed by the Brow Pop Nano in Taupe and Medium Brown, which allowed for hair-like strokes to be added for density, followed by the Air Brow Gel to set the shape. The Soulgazer Lengthening + Lifting Peptide Mascara provided the final definition, emphasizing length to open the eyes for the cameras.
The warmth of the look was reinforced through the use of The Sun Show bronzer in Beachy and Blush is Life in the shades Blissed and Swoon. The layering of these two blush shades—one a soft peach and the other a deeper rose—created a custom flush that mimicked a natural rush of color. This was topped with the Shiny Objects Powder Highlighter in Haloed and Glimmerose on the cheekbones, bridge of the nose, and Cupid’s bow.
The High-Shine Lip Architecture
The final element of the look was the lip, which required a balance of structure and hydration. As matte liquid lipsticks continue to decline in popularity in favor of glossy, high-moisture finishes, Lau opted for a three-step process. The Hotliner Hyaluronic Acid Contouring Lip Liner in Beyond was used to define the perimeter and prevent the gloss from feathering. This was followed by the Wet Stick Moisturizing Lip Shine in Heatwave, a product that bridges the gap between a lipstick and a balm.
To achieve the "glass-like" finish seen in premiere photos, the Lip Pulse Glassy Lip Plumper in Aura Flare was layered over the top. This combination provided a high-pigment, high-shine result that complemented the bronzed tones of the eyes. The look was finalized with the Cloud Set Airy Setting + Smoothing Mist, a micro-fine spray designed to lock the makeup in place for the duration of the screening and subsequent after-party.
Supporting Data: The Impact of Red Carpet Beauty on the Market
The use of Kosas products for Rachel Sennott’s premiere look is indicative of a larger trend within the $500 billion global beauty industry. Data from market research firms suggests that celebrity-endorsed "get ready with me" (GRWM) content and red carpet breakdowns drive significant spikes in consumer search volume. For instance, when a specific shade of concealer or lip gloss is identified on a high-profile actress, retailers often report a double-digit increase in sales for that specific SKU within 48 hours.
Kosas, specifically, has benefited from its positioning as a "skincare-cosmetic hybrid." According to industry reports, the brand has seen rapid growth due to its appeal to Gen Z and Millennial consumers who prioritize ingredient transparency. By featuring their products on a talent like Rachel Sennott—who possesses a strong, digitally native following—Kosas reinforces its brand identity as the go-to for "cool, effortless glamour."
Chronology of the Red Carpet Appearance
The timeline of the beauty preparation for the New York premiere followed a rigorous schedule typical of major film events:

Official Reactions and Industry Implications
While official statements from the studio regarding the film’s reception are pending, the fashion and beauty community has reacted positively to Sennott’s aesthetic choices. Social media engagement metrics indicate that the "bronzed rose" look has already been widely bookmarked as a reference for upcoming seasonal trends. Industry analysts suggest that Sennott’s ability to move between "grunge" aesthetics and "high glamour" makes her a versatile and valuable partner for luxury and beauty brands.
The implications of this look extend beyond a single night. It reinforces the shift toward "warmth" in beauty—moving away from the cold, stark contouring of the mid-2010s toward a more blended, sun-kissed, and healthy appearance. Furthermore, it highlights the technical proficiency required to make "clean" makeup products perform at the same level as traditional, silicone-heavy professional products.
Broader Impact on Celebrity Branding
Rachel Sennott’s appearance at the New York premiere of Big Mistakes is a testament to the power of a cohesive visual narrative. By aligning her fashion (Georges Chakra), her beauty artist (Samantha Lau), and her brand partner (Kosas), Sennott has created a professional "template" for the modern movie star. This approach not only promotes the film but also builds a personal brand that is synonymous with style, quality, and contemporary values. As the promotional cycle for Big Mistakes continues, the industry will likely see more iterations of this "bronzed rose" aesthetic, further cementing its place as a dominant trend for the mid-2020s.
