What is 4D Sodium Hyaluronate

On the path of pursuing beauty and skin health, people have never ceased their exploratory steps. In recent years, 4D sodium hyaluronate, also known as 4D hyaluronic acid, has emerged as a highly anticipated new star in the skincare industry. So, what exactly is 4D sodium hyaluronate? Why can it stand out among so many skin care ingredients? ​

Hyaluronic acid, abbreviated as HA, is an acidic mucopolysaccharide that is widely distributed in the skin and human tissues. Hyaluronic acid is renowned for its powerful moisturizing ability, capable of carrying 1,000 times its own weight in water. Hyaluronic acid is hailed as an ideal “natural moisturizing factor” and is currently the substance with the best moisturizing effect in nature. Sodium hyaluronate, on the other hand, is the sodium salt form of hyaluronic acid. This form is more stable and has high water solubility, making it convenient for production and use in cosmetics and other products.

4D Sodium Hyaluronate, as the name suggests, is ingeniously composed of four types of sodium hyaluronate with different molecular weights and structures. They are high-molecular sodium hyaluronate, medium-molecular sodium hyaluronate, Sodium acetylated hyaluronate and hydrolyzed sodium hyaluronate. These four types of hyaluronic acids each perform their own functions, jointly building a three-dimensional water-storing sponge layer. They precisely target different layers of the skin, achieving the outstanding effect of hydrating the outer layer, locking in moisture on the inner layer, and moisturizing layer by layer, making the skin radiate moisture and luster from the inside out. Thus achieving a comprehensive skin care effect that a single hyaluronic acid cannot reach. So, how exactly do these four components work?

High molecular weight sodium hyaluronate: As a “surface protective soldier”, its macromolecular structure can form a breathable “biological protective net” on the skin surface. Sodium hyaluronate not only reduces water evaporation but also effectively isolates some environmental pollutants and irritants, providing immediate moisturizing and protective effects. ​

Medium molecular weight Sodium hyaluronate: Focusing on “middle layer hydration”, it acts on the stratum corneum of the skin. By nourishing the keratin and forming a hydrated film, it keeps the skin soft and hydrated, while laying the foundation for the absorption of subsequent skin care ingredients. ​

Sodium acetylated hyaluronate: Known as the “guardian of the stratum corneum”, its special structure – after acetylation modification, it has both hydrophilic and lipophilic properties. Sodium hyaluronate can not only combine more closely with water but also repair damaged keratin, improving dry and rough skin problems. Its moisturizing capacity is more than twice that of ordinary hyaluronic acid, and its effect is long-lasting. It is extremely difficult to be washed away by water, achieving true long-lasting repair and moisturizing.

Hydrolyzed sodium hyaluronate: With its ultra-small molecules, it is the only component that can “penetrate deep into the skin”, capable of penetrating the skin surface to reach the dermis, repairing skin cells damaged by ultraviolet rays, replenishing moisture from the root and locking in nutrients, and enhancing skin elasticity and luster. At the same time, it stimulates the production of collagen, thereby improving dry lines and fine lines, and enhancing the skin’s moisture and elasticity from the inside out.

Traditional skin care products usually only add sodium hyaluronate of one molecular weight, which often can only achieve a single surface hydrating or deep penetration effect, and cannot balance immediate and long-lasting effects. The innovation of 4D sodium hyaluronate lies in that it simulates the different forms of hyaluronic acid naturally present in human skin. Through the golden ratio, it enables the four components to act simultaneously, forming a complete closed-loop system of “water absorption – water retention – water storage – repair”. It is no longer a “lone soldier”, but a “hydrating army” with clear division of labor and highly efficient collaboration, solving the technical pain points of traditional sodium hyaluronate that “only hydrates but does not lock in moisture” or is prone to absorbing skin moisture. Therefore, many well-known domestic and foreign beauty brands apply it to their products such as face creams, essences, and masks, covering multiple categories including basic moisturizing, anti-aging, and sensitive skin repair.
