Kendall Jenner's beauty advertisements are attracting renewed scrutiny after two separate L'Oréal Paris campaigns prompted viewers to question how convincingly the model demonstrates the products she promotes.
The 31-year-old model, who became a global ambassador for L'Oréal Paris in July 2023, appeared in a promotional video for the brand's Infaillible Cushion Foundation, released on 1 November 2026. However, some viewers focused on the appearance of her make-up applicator rather than the foundation itself, questioning whether it contained any visible product.
The reaction echoed criticism documented in September 2026, when Jenner appeared to apply skincare over an already made-up face in another L'Oréal promotion. Although neither incident establishes that she misrepresented the products, the similarities raise a broader question about what consumers expect from celebrity beauty demonstrations.
Kendall Jenner's Foundation Advertisement Revives Familiar Questions
In the November advertisement, Jenner demonstrates L'Oréal Paris's Infaillible Cushion Foundation by tapping a dark make-up puff against her face. However, some viewers on social media questioned the applicator's unusually clean appearance despite being used to demonstrate foundation. Many of them questioned whether the video clearly showed the product being applied.
Others pointed to Jenner's already polished complexion, suggesting that it was difficult to judge how much coverage the foundation provided. The appearance of the puff does not establish whether it contained foundation, and the footage alone does not prove that Jenner was pretending to apply the product.
Nevertheless, the reactions highlighted a familiar challenge for beauty advertising: a polished final appearance may attract attention, but it does not necessarily show viewers how a product performs. And for products like the Infaillible Cushion Foundation, many viewers wish to see how the product can be used rather than just the final pretty face that puts it on.
An Earlier Skincare Advertisement Faced Similar Criticism
The November foundation promotion was not Jenner's first L'Oréal Paris advertisement to generate questions about her application technique. On 27 August 2026, Jenner reportedly shared a skincare video in which she appeared to apply serum while already wearing make-up.
Criticism of the demonstration was subsequently documented on 8 September, with some viewers questioned why a skincare product was being demonstrated on a complexion that appeared professionally prepared rather than visibly bare.
The concerns differed slightly from those surrounding the foundation advertisement. While the November criticism focused on whether the applicator visibly contained product, the earlier discussion centred on whether the skincare demonstration reflected a realistic routine. In both cases, viewers questioned the presentation rather than providing evidence that the products were ineffective or that Jenner had deliberately misled consumers.
What the Two Advertisements Reveal About Beauty Marketing
The recurring questions surrounding Jenner's L'Oréal promotions highlight the tension between celebrity-led advertising and consumers' expectations of practical product demonstrations. A professionally styled campaign can communicate a brand's desired image, but viewers may also want to see how a product looks and performs during application.
Jenner's two advertisements illustrate why that balance matters. Both ads prompted essentially the same question: are viewers seeing a convincing product demonstration or primarily a carefully presented beauty look?
