A modified version of regular hyaluronic acid. It attracts large volumes of water, thereby making it an effective humectant moisturizing ingredient.

Sodium hyaluronate crosspolymer (SHC) is a modified version of regular hyaluronic acid (read about it here).
If you imagine hyaluronic acid as really long strands, then a crosspolymer means that several of these HA strands have been linked between each other, creating a huge 3D mesh that can cling to the skin’s surface and bind large volumes of water, making it a super effective humectant moisturizing ingredient. It is also used in HA filler injections.
There is a study that compares SHC with other types of hyaluronic acid when applied to samples of human skin. The study found that SHC was superior in its humectant properties to other types of HA.
Another study using SHC in combination with other ingredients also showed very good results in the moisturization parameters.
The massive size of the HA mesh, however, means that this version of hyaluronic acid will not get absorbed into the skin and won't offer much in terms of collagen support and anti-wrinkle effects like Low Molecular Weight HA does.
