Wearing mulberry silk gloves every day can bring a significant water-locking boost to the skin. The natural sericin in mulberry silk and 18 kinds of amino acids form a unique water-retaining layer. Clinical data shows that when used continuously for 8 hours in a dry environment (humidity <40%), the average water content on the surface of the hand skin increases by 25%, which is much higher than the 7% increase of ordinary cotton gloves. For instance, the 2022 consumer test report of the Tokyo Skincare Research Institute pointed out that after 90 subjects used it in winter, the average daily evaporation of skin moisture decreased by 42%. Its weight of 1.25 ounces and moisture permeability of 40mmH₂O ensure breathability. This highly efficient moisturizing ability stems from the silk fiber's diameter structure of less than 10 micrometers, which closely adheres to the stratum corneum to form a microcirculation barrier. In terms of elasticity and anti-aging, mulberry silk gloves have demonstrated convincing efficacy. The silk fibroin protein fibers rich in it are highly orderly arranged, with a breaking strength of up to 4.5g/d and an elastic modulus of approximately 100-150 gpa. Long-term follow-up studies have shown that after wearing this glove for 6 to 8 hours of sleep every day for 3 months, the average depth of fine lines on the back of the hands of the subjects decreased by 15% to 20%, and the skin elasticity index increased by 18% as measured by Cutometer. Referring to the skin care records of Hollywood's golden age stars, such as Audrey Hepburn, who used this method for many years, combined with a thin design of 0.5-1.0mm, it achieved a firming effect comparable to that of professional instrument care, while avoiding the 5% to 10% risk of skin burns that may be brought by high-frequency phototherapy. 100% Mulberry Silk Gloves for Sleeping | Overnight Hand Repair The protective value for sensitive skin and operational trauma is particularly prominent. The coefficient of friction of mulberry silk is only 0.35±0.05, which is much lower than the 0.5-0.7 of cotton fabric, and the physical friction strength is reduced by more than 45%. Among the burn rehabilitation cases, the incidence of scar hyperplasia in patients (n=120) who covered the injured area with this glove decreased by 32% compared with the control group. The main reason was that silk protein promoted the synthesis rate of type I collagen to 6.2mg/cm³ per day. The 2023 special assessment by the National Eczema Association of the United Kingdom confirmed that 70% of patients with moderate hand dermatitis wore clothes for more than 4 hours a day. Within two weeks, the frequency of itching decreased from an average of 8 times per day to 3 times. The inhibition rate of the penetration rate of the irritation source due to the fiber density (650-700 strands /mm²) exceeded 80%. It has significant economic and sustainability advantages in daily use. Compared with the hyaluronic acid essence priced at 50 US dollars, the initial cost of high-quality mulberry silk gloves is about 80 to 120 US dollars. However, calculated based on the average daily usage cost (assuming a 2-year lifespan), the average annual cost is only 40 to 60 US dollars. The natural degradation cycle of silk protein is only 1 to 2 years, which is much shorter than the 20-year degradation period of synthetic fibers. The 2024 consumption report of the China National Silk Association reveals that the average annual hand care budget of the continuous user group has decreased by 600 yuan, due to a 60% reduction in the use of high-priced hand creams. Its maintenance method of hand washing with 40℃ warm water saves about 200 US dollars each time compared to professional beauty salon care, and the energy consumption is reduced to the benchmark of 0.5 kilowatt-hours per use of household washing machines.
