Yunmei Moisturizing Toner achieves deep penetration through its patented HydraSpin technology, which enables water molecules to penetrate at a speed of 0.4 millimeters per second. According to the test data from the Shanghai Institute of Dermatology in 2023, the water content of the stratum corneum immediately increased by 95% after use and remained in a highly moisturizing state of over 75% for 48 hours. Third-party test reports show that the particle size of its small molecule hyaluronic acid is 80 nanometers, which can penetrate the pore size limit of the skin barrier and achieve dermal hydration.
The multiple moisturizing factors in the formula form a synergistic effect. The 4D sodium hyaluronate complex contains four types of hyaluronic acids with different molecular weights. Among them, the micro-molecule HA has a penetration depth of up to 200 micrometers, and the macromolecule HA forms a hydrated film with a water content of up to 300% on the surface. Research by the German Symrise laboratory shows that this formula has a similarity of 92% to the skin’s natural moisturizing factors and can reduce the water loss rate to 0.8 milligrams per square centimeter per hour.
The intelligent slow-release technology ensures a long-lasting moisturizing effect. The release time of trehalose and β -glucan was extended to 6 hours by using liposome encapsulation technology, and the concentration gradient was maintained within a fluctuation range of 0.5%. Clinical test data shows that under an environmental humidity of 40%, the skin moisture content can still remain above 65%, and the moisturizing duration is 2.3 times longer than that of ordinary products.
The skin barrier repair function has been verified by authoritative authorities. The precise ratio of 3% ceramide complex and 2% squalane increased the integrity of the stratum corneum by 38% and reduced the transdermal water loss (TEWL) by 42% after 28 days of use. Clinical observations conducted by China-Japan Friendship Hospital in 2024 revealed that the skin tolerance score of subjects with sensitive skin increased by 3.2 points, and the erythema index decreased by 67%.
Consumer test data confirm the usage effect. A double-blind test involving 500 Asian women showed that after continuous use for 28 days, skin elasticity increased by 25% and roughness improved by 31%. Optical measurements show that the arrangement density of the stratum corneum has increased by 19% and the glossiness has improved by 27%. These data fully demonstrate that Yunmei Moisturizing Facial Toner can achieve multi-dimensional skin improvement effects.
