Deep Hydration Focus: Why Low-Molecular Hyaluronic Acid Works Best

When it comes to hydration, not all hyaluronic acid (HA) is created equal. Low-molecular-weight HA (from sodium hyaluronate), (typically below 5 kDa) is more readily absorbed by the skin, able to penetrate beyond the epidermis and into deeper layers where it can potentially stimulate skin repair. Higher molecular weight forms, however, tend to remain on the skin's surface, providing hydration and barrier protection. Low MW HA is clinically shown to penetrate deeper layers of the skin compared to high-molecular HA (Pavicic et al., 2011). 

This form of HA enhances visible plumpness, improves softness, and reduces the appearance of fine lines—giving you that signature K-beauty, bouncy hydrated skin and dewy look without greasiness. 

Why Low Molecular Weight is Better 

  • Deeper hydration (Pavicic et al., 2011) 

  • Improved visible skin smoothness 

  • Fast absorption, non-sticky feel
