Description

Product Name: 4D Multiple Sodium Hyaluronate Solution
Molecular Weight Range: Multi-molecular composition (High, Cross-linked, Acetylated, Hydrolyzed Low Molecular Weight HA)
Appearance: Clear, colorless to light yellow viscous liquid
Functions: Multi-layered hydration, moisture retention, skin barrier repair, elasticity enhancement
Molecular Formula: Mixture of various HA forms
Molecular Weight: Multi-level, actual measured values

Key Benefits & Features:
1.High Penetration: Hydrolyzed low molecular weight HA penetrates deeply into the dermis, delivering hydration directly where it is most needed, while also providing anti-inflammatory and antibacterial effects.
2.Skin Affinity & Repair: Acetylated HA combines lipophilic and hydrophilic properties, increasing adhesion to the stratum corneum. It promotes double hydration, repairs damaged epidermal cells, and enhances skin elasticity.
3.Surface Moisture Retention: Conventional HA molecules form a protective layer on the skin surface, locking in moisture and improving absorption of nutrients from other active ingredients.
4.Long-Lasting Lock & Protection: Cross-linked HA polymers, formed through HA cross-linking reactions, create ultra-high molecular weight networks on the skin surface, providing long-lasting hydration, barrier protection, and environmental defense.

4D Multiple Sodium Hyaluronate Solution – Frequently Asked Questions (FAQ)

1. What is 4D Multiple Sodium Hyaluronate Solution?

Answer:
4D Multiple Sodium Hyaluronate Solution is an advanced moisturizing ingredient that integrates four different forms of sodium hyaluronate—high molecular weight HA, cross-linked HA, acetylated HA (AcHA), and hydrolyzed ultra-low molecular weight HA. This multi-dimensional system provides deep, long-lasting hydration and comprehensive skin repair from the surface to the dermis.

---

2. What makes the “4D” technology unique?

Answer:
The “4D” concept refers to the synergistic action of four distinct types of hyaluronic acid, each targeting different skin layers. The result is a continuous hydration network that locks in moisture, strengthens the skin barrier, and improves elasticity at multiple depths.

---

3. What are the main functions of each HA type in the formula?

Answer:

• High Molecular Weight HA: Forms a protective film to prevent moisture loss and provide instant hydration.

• Cross-linked HA Polymer: Creates a long-lasting hydration reservoir and reinforces the skin barrier.

• Acetylated HA (AcHA): Enhances adherence to the skin, repairs damaged cells, and boosts elasticity.

• Hydrolyzed HA (Ultra-Low MW): Penetrates deep into the dermis for intensive hydration and anti-inflammatory effects.

4. What are the key benefits of using this ingredient in formulations?

Answer:
It offers multi-layer hydration, long-term moisture retention, skin barrier repair, elasticity improvement, and anti-aging support. It helps create smooth, plump, and radiant skin when used in skincare products.

---

5. What types of formulations is this ingredient suitable for?

Answer:
4D Multiple Sodium Hyaluronate Solution can be widely applied in serums, creams, lotions, facial masks, essences, gels, sprays, and other water-based or emulsion-type skincare products.

---

6. How should it be used in cosmetic formulations?

Answer:
The recommended usage level is typically 0.5–5.0%, depending on the product type and desired moisturizing effect. It should be added during the cooling phase (below 40°C) to preserve its bioactivity.

---

7. What is the appearance and solubility of this product?

Answer:
It is a clear, colorless to slightly transparent viscous liquid, fully water-soluble and compatible with most cosmetic ingredients.

---

8. Is 4D Multiple Sodium Hyaluronate Solution safe and stable?

Answer:
Yes. It is non-toxic, non-irritating, and biocompatible, with excellent formulation stability under normal storage conditions. It is compliant with global cosmetic regulations and suitable for all skin types.
