In our Laboratory, we continually expand our database of more than 10,000 ingredients. We use it to analyse ingredients and develop new formulas — selecting those with proven effects.

5D Multi-Level Hyaluronic Acid

A complex of five complementary forms of hyaluronic acid with different molecular weights, developed to support hydration at multiple levels of the skin. Smaller and larger forms perform distinct yet complementary roles, helping hydrate the skin from the surface to deeper layers while supporting softness, smoothness and elasticity.

Unlike conventional formulas based on a single form of hyaluronic acid, the 5D system works across multiple levels. Rather than concentrating its action at a single level, it creates a more even, multidimensional effect — combining immediate surface hydration with longer-lasting moisture retention.

A key component is Sodium Hyaluronate Crosspolymer, a cross-linked form of hyaluronic acid. Its three-dimensional structure creates a hydrating micro-network on the skin that binds water and releases it gradually. This helps limit rapid moisture loss and supports lasting comfort, softness and smoothness.

The complex therefore works not only by attracting water, but also by helping maintain more stable hydration across different levels of the skin.
