Mechanism of Action
1. Highly Efficient Water Absorption and Lock-in Mechanism
The hydroxyl and carboxyl groups on the sodium hyaluronate molecular chain can form a stable hydrogen bond network with water molecules, thereby storing a large amount of water on the skin surface and in the stratum corneum, achieving the dual effects of immediate hydration and long-lasting moisturization.
2. Building a Skin Protective Barrier
Sodium hyaluronate forms a uniform hydration film on the surface of the stratum corneum, helping to repair damaged barrier structures, reducing the invasion of external irritants, and slowing down the rate of water evaporation.
3. Improving Skin Feel and Lubrication Properties
The unique viscoelasticity of sodium hyaluronate makes the product smoother during application, significantly improving the user experience and making the skin feel softer, smoother, and more elastic.
4. Assisting in Anti-Aging and Fine Line Improvement
By continuously maintaining skin moisture content, sodium hyaluronate reduces fine lines and roughness caused by dryness, thereby improving the overall appearance of the skin and making it look fuller and younger.
Molecular Weight & Applications
1. High Molecular Weight Sodium Hyaluronate
Primarily stays on the skin's surface, forming a dense hydrating film to achieve immediate moisturizing and water-locking effects. Particularly suitable for face creams, sleeping masks, and repair products.
2. Medium Molecular Weight Sodium Hyaluronate
Possesses both permeability and film-forming ability, improving skin feel while hydrating. Widely used in daily skincare products such as lotions and serums.
3. Low Molecular Weight Sodium Hyaluronate
With smaller molecules, it penetrates more easily into the stratum corneum, helping to deeply hydrate and improve dryness. Suitable for functional serums and highly effective hydrating products.
4. Oligo Sodium Hyaluronate
With an even lower molecular weight, it has stronger permeability and is often used in high-end skincare formulations to enhance product functionality and differentiate its competitiveness.
Usage Recommendations
Recommended Dosage: Generally 0.05% – 0.5%, the specific dosage can be adjusted according to product positioning and target efficacy.
Addition Method: It is recommended to pre-disperse or dissolve in deionized water to form a uniform and transparent solution before adding to the system.
Processing Conditions: Avoid prolonged processing in high-temperature (>60℃) environments to prevent molecular structure degradation that could affect performance.
Formulation Suggestions: Sodium hyaluronate can be used in combination with moisturizers such as glycerin and propylene glycol to enhance the overall moisturizing effect.
