4D Hyaluronic Serum harnesses four advanced forms of Sodium Hyaluronate, each selected for its unique molecular weight and affinity with the skin. This multi-dimensional hydration system creates a four-dimensional moisture network, helping reduce transepidermal water loss while delivering complete, multi-layer hydration. Ultra-high molecular weight Sodium Hyaluronate Crosspolymer forms a protective film on the skin surface, high molecular weight molecules nourish and hold water, Sodium Acetylated Hyaluronate adheres to the stratum corneum for lasting hydration and ultra-low molecular weight Hydrolyzed Sodium Hyaluronate penetrates deeper to support visible elasticity, leaving skin plump, smooth and supple.
- 4D Multi-Layer Hydration: Four forms of Sodium Hyaluronate work together to create a three-dimensional hydration network, supporting moisture across multiple layers of the skin for a smoother, plumper-looking complexion.
- 24-Hour Moisture Support: Ultra-high molecular weight Sodium Hyaluronate Crosspolymer forms a breathable protective film on the skin’s surface to help reduce water loss and keep hydration locked in.
- Barrier-Loving Protection: This advanced hydration shield supports barrier function while helping defend against everyday environmental stressors, including pollution and UV-related dehydration.
- Surface Softening: High molecular weight Sodium Hyaluronate nourishes and holds water at the skin surface, while Sodium Acetylated Hyaluronate adheres to the top layer of skin to support smoother, softer and more supple skin.
- Deep Hydration From Within: Ultra-low molecular weight Hydrolyzed Sodium Hyaluronate rapidly penetrates deeper skin layers to support moisture, visible elasticity and skin bounce from within.
- Plumping & Smoothing: By combining four Hyaluronic Acid technologies, this serum helps improve the look of fine lines, dryness, texture and dehydration for skin that feels fresh and deeply hydrated.
