Difference Between 4D and 8D Hyaluronic Acid

The main difference between 4D Hyaluronic Acid and 8D Hyaluronic Acid lies in the variety of hyaluronic acid molecules they contain, which affects their ability to provide hydration to different layers of the skin.

• 4D Hyaluronic Acid contains four types of hyaluronic acid molecules: small, medium, large, and cationic. This combination works to create a three-dimensional network that helps retain moisture on the skin surface and in the upper layers (cuticle, epidermis, and dermis).

• 8D Hyaluronic Acid contains a broader spectrum of eight types of hyaluronic acid molecules. This includes four different molecular sizes (small 10K, medium 800K and 1M, large 2M Daltons), plus cationic, cross-polymer, and acetylated types. The addition of cross-polymer and acetylated hyaluronic acid is significant.

While both products are designed for hydration and have the same recommended usage rate (1-20%), the more complex composition of 8D Hyaluronic Acid is intended to provide more comprehensive benefits:

• Cross-polymer Hyaluronic Acid forms a stable, gel-like network that provides long-lasting hydration and helps improve skin elasticity.
• Acetylated Hyaluronic Acid (also known as Super Hyaluron) has enhanced absorption into the skin compared to other types.

Therefore, yes, 8D Hyaluronic Acid is expected to provide better and more comprehensive hydration because it includes a wider range of hyaluronic acid types that target different depths of the skin and offer additional benefits like enhanced absorption and longer-lasting moisture retention compared to 4D Hyaluronic Acid.
