What is '3D hyaluronic acid' and how does it work differently in this mask?

The term '3D hyaluronic acid' refers to the use of hyaluronic acid in multiple forms or structures within the formula. Hyaluronic acid is a moisture-binding substance that helps attract and hold water in the upper layers of the skin. As described for this mask, using different forms creates a more layered hydrating effect where some moisture remains nearer the skin's surface to provide immediate smoothness and a plumper look, while other fractions work to improve the feeling of skin elasticity. This approach is common in cosmetics aiming for multi-depth hydration. It does not refer to a literal three-dimensional shape, but rather to the concept of delivering hydration at different levels within the skin's surface layers for a more comprehensive effect.
