Hyaluronic Acid Crosspolymer is a chemically cross-linked form of hyaluronic acid designed to form a hydrated, film-forming network that retains moisture and provides longer-lasting hydration than standard hyaluronic acid. It is commonly used in moisturizers and serums to improve skin surface hydration and smoothness.

| Contact dermatitis or allergic reaction | Very rare | Hyaluronic acid derivatives are generally well tolerated; sensitization is uncommonly reported. |
| Skin tightness or dryness in very low-humidity environments | Rare | Humectants may draw moisture from skin if not sealed with an occlusive in dry conditions. |
