美妆再陷EGF罗生门，科学之光为何照不透舆论迷雾？

Core Viewpoint - The beauty industry is currently facing scrutiny due to the detection of the banned substance EGF (Epidermal Growth Factor) in products from various brands, including KANS, which has sparked significant media attention and consumer concern [3][9]. Summary by Sections Detection of EGF - A report from CCTV's "Economic Half Hour" highlighted the presence of EGF in KANS products, specifically the "KANS Firming Essence Mask" and "KANS Brightening Mask," with detected levels of 0.07 pg/g and 3.21 pg/g respectively [3][4]. KANS Response - KANS responded by asserting that none of their products contain EGF and provided third-party testing results from SGS, confirming the absence of EGF in the mentioned products. They emphasized compliance with national regulations [5][8]. Understanding EGF - EGF is a naturally occurring substance in human tissues, known for promoting cell growth. However, its use in cosmetics is restricted in many countries due to potential risks associated with excessive use [8][9]. Previous Incidents - The EGF controversy is not isolated; earlier in 2025, a similar incident involved multiple brands being accused of EGF contamination, which was later disproven by regulatory testing [9][10]. Microbial Presence of EGF - The detected levels of EGF in KANS products are extremely low, raising questions about the likelihood of intentional addition. Experts argue that such minuscule amounts would not provide any therapeutic benefits and suggest that the presence of EGF is unlikely to be a deliberate act by KANS [10][12]. Testing Methodology Concerns - Experts suggest that the detection of EGF may stem from issues with the testing methods used, particularly the ELISA method, which lacks standardized protocols for cosmetic products. This could lead to inaccurate results [16][18]. Industry Implications - The beauty industry faces ongoing challenges related to detection standards and the impact of media-driven narratives on brand reputation. The lack of clear regulations and testing standards contributes to the potential for misinformation and public backlash [19][20].
