Ingredient Spotlight: The Science of 4D Hyaluronic Acid

Hyaluronic Acid (HA) is famous for its ability to hold up to 1000 times its weight in water. However, a single type of HA molecule primarily provides surface hydration. To achieve deeper, more comprehensive moisture, we use a sophisticated 4D Hyaluronic Acid Complex in our LUSTRA Acne Moisturising Cream (LUS-002).

Hydration from Every Angle

Our complex provides moisture at four different levels of the skin for a comprehensive, three-dimensional effect:

1. Sodium Hyaluronate Crosspolymer: Forms a protective, dense '3D sponge' on the skin's surface for continuous, long-lasting hydration and pollution protection.
2. Sodium Hyaluronate: The classic form that holds water on the skin's surface, providing immediate plumping and preventing water loss.
3. Sodium Acetylated Hyaluronate ('Super HA'): Adheres tightly to the skin's top layer (the stratum corneum), doubling the hydration capacity of standard HA.
4. Hydrolyzed Sodium Hyaluronate: A low-molecular-weight form that penetrates deeper into the epidermis, providing hydration from within and supporting skin repair.

The Multi-Layered Benefit

// A simplified model of the 4D HA action
const hydrationSystem = {
  layer1_surface: ['Crosspolymer', 'Sodium Hyaluronate'],
  layer2_top_epidermis: ['Acetylated Hyaluronate'],
  layer3_deeper_epidermis: ['Hydrolyzed Hyaluronate'],
  total_effect: 'Comprehensive, Multi-Level Hydration'
};

By targeting different layers of the skin simultaneously, this advanced complex ensures that oily and acne-prone skin receives the thorough, water-based hydration it needs to stay balanced, healthy, and calm.
