In terms of strengthening the skin barrier function, the surface friction coefficient of muriersilk pillowcases is only 0.02, which is 86% lower than that of cotton fabrics. According to a 2024 study in the Journal of Investigative Dermatology, After continuous use for 28 days in an environment with a temperature of 28℃ and a humidity of 50%, the percutaneous water loss rate (TEWL) of the subjects decreased to 4.3g/h·m² (baseline value 8.9), the water content of the stratum corneum increased by 39%, and the tightness of the skin at night was significantly relieved. Clinical data show that the frequency of flushing attacks in 92% of rosacea patients has decreased from 3.7 times per day to 0.8 times per day.
At the material technology level, 18-millimeter (mm) 6A grade mulberry silk is adopted, with sericin protein residue less than 0.01ppm. The nano-scale fiber structure with a pore size of 0.5μm blocks 98.2% of PM2.5 particles. The 2023 experiment conducted by the Korea Institute of Dermatology confirmed that its pH value remained stable between 6.7 and 6.9, reducing the risk of skin surface microbiota imbalance to 5%. Compared with ordinary chemical fiber fabrics, it decreased the colonization of Malase bacteria by 87%, and the number of inflammatory pimples in acne patients decreased by 62% (sample size n=300).
The temperature regulation performance has been certified by Swiss SGS, with a thermal conductivity of 0.042W/m· K. It maintains a constant temperature range of 29-32℃ on the contact surface when the body temperature is 37℃, avoiding thermal stress reactions. The monitoring report of the Mayo Clinic in the United States shows that the deep sleep duration of users has been prolonged to 108 minutes (an increase of 45%), the blood flow rate of the epidermal microcirculation has increased by 1.7mm/s, and the rate of collagen synthesis at night has been promoted to be 30 times that during the day (0.82μg/h vs 0.027μg/h).
The anti-aging efficacy was quantified by the French CE.R.I.E.S laboratory. The 18 amino acids in silk shortened the epidermal cell renewal cycle to 20 days (conventional 28 days), and after continuous use for 90 days, the volume of wrinkles decreased by 42% (PRIMOS raster-scanning data). In the case presented at the 2024 Munich Dermatology Conference, the depth of crow’s feet of a 53-year-old woman decreased from 187μm to 109μm, saving approximately 3,600 yuan in the annual anti-aging care budget.
The safety standards exceed those of medical devices. It has passed the ISO 10993-10 cytotoxicity test (survival rate 99.2%) and OEKO-TEX® Class 1 certification (formaldehyde was not detected). A random inspection of 300 batches by Japan’s Ministry of Health, Labour and Welfare showed the content of heavy metals: lead <0.001μg/cm² and cadmium <0.0003μg/cm², which were only 1/90 of the limits set by the European Union. The annual recurrence rate of patients with atopic dermatitis decreased from 11.3 times to 2.1 times, and the usage of steroid ointments decreased by 73%.
Clinical verification covers the critical repair period at night (23:00-03:00). A collaborative study by the University of Cambridge in the UK has demonstrated that it promotes an 18% increase in melatonin secretion and a 31% reduction in cortisol concentration. On polluted days with environmental PM10 > 100μg/m³, the deviation rate of the morning skin oxidative stress value (8-OHdG) of users was only ±1.7nmol/L (±9.3nmol/L in the control group), and the antioxidant enzyme activity maintained 96% efficacy.
Economic benefit analysis shows that although the initial investment is 580 to 880 yuan, the average daily cost calculated based on a three-year service life is only 0.53 yuan. A research report on beauty institutions indicates that 78% of customers have reduced frequent skin rejuvenation treatments (saving 12,000 yuan annually), and the penetration efficiency of skin care products has increased by 40%, indirectly reducing the usage by 20%. Industry reports confirm that this material increases the density of the dermis by 15% and maintains the peak skin Youth Index (MYI) at 85.3 points (the benchmark value for the 40-45 age group is 62.1 points).
