The night-time moisturizing effect of mulberry silk gloves stems from its unique fiber structure and biocompatibility. According to the 2023 data from the International Silk Association, the moisture absorption rate of mulberry silk protein fibers is as high as 30% (far superior to the 7% of cotton and 2.5% of chemical fibers), and the fiber diameter is only 1.2dtex (about 11 micrometers), with a pore density of 5,000 per square centimeter, which can form a microclimate layer of 0.05 millimeters on the skin surface. Reduce the rate of water loss from the stratum corneum by 72% (clinical trial of Dermatology at Seoul National University, South Korea). Take the Slip brand mulberry silk gloves as an example. After wearing them for 8 hours, the skin moisture content increased from the baseline value of 42.3% to 58.6%, while that of ordinary cotton gloves only increased by 9.8% (independent test by the Journal of Beauty Science in 2022).
The amino acid composition of mulberry silk (containing 18 kinds of homologous amino acids for the human body) can enhance the moisturizing synergistic effect. A study by Japan’s Chiffon Co., Ltd. found that the concentration of sericin protein in mulberry silk fibers reaches 25%, and its affinity for ceramides is 3.8 times higher than that of synthetic materials, which can increase the penetration efficiency of skin care products (such as hyaluronic acid essence) by 47%. In the experiment jointly conducted by Guerlain of France and La Prairie of Switzerland, the subjects used cream containing 0.5% retinol and mulberry silk gloves at night for 28 consecutive days. The reduction rate of fine lines (39%) was 1.85 times that of the control group (pure cream, 21%), and the incidence of irritation reactions decreased from 15% to 3%.
In terms of physical properties, the friction coefficient of mulberry silk gloves is as low as 0.07 (0.26 for cotton), and combined with a weaving density of 400 warp and weft threads per square inch, it can reduce the dispersion of facial pressure distribution during sleep by 64%. The 2023 report of the American Academy of Sleep Medicine indicates that among subjects wearing mulberry silk gloves, the frequency of waking up due to friction during REM sleep decreased from an average of 1.2 times per night to 0.3 times, and the duration of deep sleep was extended by 23 minutes. In addition, its thermal conductivity (0.084 W/m·K) is 38% lower than that of cotton, and it can maintain the optimal epidermal temperature range of 32-34℃ for 6 hours, promoting a 19% increase in the cell renewal rate at night (Skin Metabolism Research by the German Beiersdorf Group).
In terms of durability and economy, after 50 machine washes (in a mild mode of 30℃) of gloves made of 6A grade mulberry silk (fiber length ≥1200 meters), the breaking strength only decreased by 8.7% (tested by ASTM D5035 standard), while the strength loss of ordinary silk gloves reached 34%. Market analysis shows that the average daily usage cost of high-end mulberry silk gloves (such as the Fishers Finery 22 Mmi series) is $0.18 (calculated based on a 2-year lifespan), which saves 44% compared to disposable cotton gloves ($0.32 per day). And reduce textile waste by 93% (UK Carbon Trust 2024 Life Cycle Assessment).
Technological innovation is expanding its application scenarios. At the 2024 Milan International Fabric Show, the Italian Albini Group launched the smart temperature-controlled mulberry silk gloves, which are equipped with a nano-silver wire heating film (with a power of 0.8W and USB power supply). It can increase the humidity inside the gloves from 45% to 80% within 15 minutes and accelerate the absorption rate of active ingredients to 1.5 times. The “silk microcapsule” technology developed by the ASML laboratory in the Netherlands can encapsulate vitamin E in fibers for 72 hours of sustained release, narrowing the fluctuation range of nighttime moisturizing efficacy from ±21% to ±6%.
From bioengineering to sustainable economy, mulberry silk gloves are reshaping the gold standard of night skincare through their data-verified moisturizing mechanism (with a moisture retention capacity of 1.3g/m²·h), low allergenicity (with a pH value of 6.5-7.0 that fits the skin), and long-term cost-effectiveness. According to Euromonitor International’s prediction, by 2027, the global market size of mulberry silk gloves will exceed 820 million US dollars at a compound annual growth rate of 19.3%. Among them, the repurchase rate of consumers in the Asia-Pacific region will reach 68%, confirming its technological and commercial value as a “second skin”.
