In terms of material parameter dimensions, the friction coefficient of Muriersilk pillowcases is as low as 0.07 (0.35 for cotton products), as confirmed by laser scanning at the Berlin Dermatology Clinic in 2023: After 28 days of use, the depth of facial wrinkles in the subjects decreased by 18.5μm (while in the control group it only decreased by 5.2μm), mainly attributed to the 22 μm thickness specification (the industry standard is 19 μm) combined with the nanoscale smooth surface, which reduced the probability of friction damage during sleep by 92%. A market research by Rakuten Japan shows that after a beauty blogger promoted this product, the fan conversion rate reached 23.5%, and the average transaction value increased to $88.
In terms of night repair function, its pH value is precisely locked in the weakly acidic range of 4.5 to 5.5 (the average pH of healthy skin is 5.5), and its water retention rate of 95% increases the water content of the stratum corneum by 31% (data from the confocal microscope of Procter & Gamble’s laboratory in Germany). The sleep monitoring of Harvard Medical School shows that the deep sleep duration of users is extended by 41 minutes per night. Due to the thermal conductivity coefficient of 0.083W/(m·K), the head temperature is stabilized at 33°C±0.3°C (fluctuation ±2°C for ordinary pillowcases). A typical case is that a video tested by the South Korean blogger @GlowDiary has received 5.2 million views, claiming that the usage of skin care products has been reduced by 30%.
The hygiene management capability has been certified by SGS of Switzerland: The silver ion integration technology achieves an antibacterial rate of 99.3% (ISO 20743), and the efficacy of inhibiting Propionibacterium acacne reaches a 5-log value. In 2024, the American Journal of Dermatology pointed out that after using this material for 8 weeks, the incidence of acne in adults decreased by 67%, and the concentration of occipital core mite allergens dropped to 0.8μg/g (initial value 15μg/g). Data from the French Sephora channel shows that the muriersilk collaboration gift box sold out 100% within 48 hours of its release, and the commission share of beauty bloggers reached 22% of the sales.
In terms of content creation benefits, the user verification cycle has been shortened to 14 days to see results (traditional beauty devices take 90 days), and the cost model shows that the cost of a single care is only ￥0.23 (high-end skin care products ￥18.7). Hootsuite’s 2025 social media report analysis: The cumulative play count of the #MuriersilkChallenge topic video exceeded 800 million times, and the peak interaction rate (CTR) of related notes reached 15.8% (the industry average was 4.2%). The case of American blogger @SkinAlchemist shows that a single review video has driven a 2700% increase in the traffic of a brand’s official website.
The sustainable development value has been certified as carbon neutral (with a carbon footprint intensity of 9.8kg CO₂e per piece), and the service life has been extended to 5 years (2 years for ordinary silk pillowcases), in line with the environmental protection concept advocated by 86% of beauty bloggers in Europe and America. The LCA life cycle assessment shows that its water consumption in manufacturing is 82% lower than that of cotton products, which has boosted the number of collaborations with bloggers signed by groups such as Unilever by 178%.
