Facial recognition technology has rapidly become a staple in airport security and immigration screening worldwide, promising quicker, more efficient identity verification. It’s often praised for its ability to streamline passenger flow and reduce human error. However, a recent case at Shanghai airport exposed an often overlooked vulnerability of these systems: their difficulty in accurately identifying faces altered dramatically by makeup. A Chinese woman, donning what was described as “bridal-level” makeup, faced an embarrassing ordeal when facial recognition scanners couldn’t verify her identity. She was asked to remove her makeup before the scanners could recognize her, and this moment quickly spread across Chinese social media, fueling broader discussions about the intersection of biometric technology, personal expression, cultural values, and privacy.
Facial recognition technology fundamentally depends on analyzing stable, distinctive facial landmarks—the relative distances between the eyes, cheekbone shapes, jaw contours, and other features—to cross-verify an individual’s identity against a stored image like a passport photo. The premise here is that these facial features remain reasonably consistent between different photos and real-life appearances. Heavy makeup, especially the kind applied for weddings or special occasions, deliberately reshapes and enhances these landmarks. Through contouring, exaggerated eye makeup, false eyelashes, and strong lip colors, it can obscure natural skin textures and dramatically alter perceived facial proportions. The Shanghai incident highlights how these cosmetic modifications can confound even advanced AI-driven facial recognition algorithms, which are still less capable of dealing with such deliberate and extensive changes.
It’s worth emphasizing that despite technological advancements in AI and machine learning, facial recognition systems remain fragile when faced with altered appearances beyond the norm. Makeup isn’t the sole complicating factor—changing lighting conditions, the presence of accessories like glasses or masks, signs of aging, and even subtle shifts in facial expression can impair accuracy. In this sense, the reliance on automated identity systems at airports assumes a level of visual consistency that isn’t always realistic in a diverse, dynamic population. For travelers whose outward appearance conspicuously deviates from their official photos, this creates a risk of delays and discomfort, as what should be a routine security measure becomes an unexpected ordeal.
Beyond the technological challenges, there’s a rich cultural dimension to consider. In many East Asian societies, makeup is not merely a cosmetic afterthought but a refined art form, deeply integrated into expressions of personal and social identity. Bridal makeup, in particular, is designed to dramatize features and create an idealized version of the wearer, embodying both artistry and tradition. The woman at Shanghai airport wasn’t hiding behind her makeup to trick machines; her “bridal-level” look was a celebration of culture and a highly valued form of personal expression. Being compelled to remove such makeup at an airport checkpoint represents more than just a security protocol—it intersects with sensitive issues around autonomy, dignity, and respect for individual presentation. Publicly wiping off a carefully curated appearance inflames privacy concerns and can induce embarrassment, turning a security checkpoint into an unwanted spectacle. Many social media users reacted with sympathy toward the woman and criticism toward an inflexible security process that failed to accommodate cultural and personal variations.
Airports increasingly turn to facial recognition due to its efficiency in fraud prevention and passenger throughput. Automated systems reduce reliance on manual identity checks, decreasing human errors and speeding up lines. However, the Shanghai incident draws attention to the practical trade-offs inherent in such technology. By demanding a narrow, uniform standard of appearance for effective scanning, these systems unintentionally exclude individuals who do not conform to expected norms, whether because of makeup styles, cultural dress, or other personal variations. This can create bottlenecks and alienate travelers, especially those whose appearance reflects diverse cultural aesthetics.
Experts in biometric security suggest multiple pathways for addressing these shortcomings. One approach would be enhancing algorithmic robustness by training facial recognition models on a broader, more diverse range of facial presentations—including variations caused by makeup, lighting, and accessories. Alternatively, deploying complementary biometric methods such as fingerprint or iris scans can offer fallback options to accommodate faces that challenge facial recognition. Such multimodal verification ensures that strict adherence to a single biometric failsafe does not penalize legitimate travelers.
Equally important is the ethical dimension. The public removal of makeup for biometric compliance goes beyond technology—it intrudes on a person’s right to self-expression and privacy, exposing personal aesthetics to official scrutiny and public gaze. As facial recognition technology becomes more ubiquitous outside airports, these privacy and dignity concerns grow more urgent. Institutions implementing such systems need policies that minimize public humiliation and respect human diversity without undermining the efficacy of security measures.
The “too glam to scan” viral incident at Shanghai airport acts as a lens for examining the intersection of cutting-edge security technology with evolving social and cultural realities. Technologists have a clear challenge: improve the adaptiveness of facial recognition through more inclusive data and smarter algorithms. Simultaneously, policymakers and airport authorities should adopt compassionate verification protocols that reduce embarrassment and uphold traveler dignity during manual checks. Educating the public about how makeup and facial cosmetics may affect biometric screening, offering guidelines for travelers, and providing alternatives when needed can ease tensions in day-to-day operations.
Ultimately, this story uncovers tensions between technological efficiency and human complexity. As airports and other institutions continue integrating facial recognition into security frameworks, balancing speed and safety with accommodation for individual appearance and cultural expression will be key. Automation is undeniably transformative, but without flexibility and sensitivity to people’s diverse, real-world faces, it risks turning ordinary journeys into undue hassle. The Shanghai experience reminds us that technology must be designed and applied in ways that honor human variety, dignity, and the richness of self-presentation, rather than demanding conformity to rigid visual norms.
