Galactoarabinan is a plant-derived polysaccharide (commonly sourced from larch trees) used in skincare as a moisturizing humectant and film-forming agent. It helps reduce transepidermal water loss, smooth the skin surface, and may enhance penetration of other ingredients.

|---|---|---|
| Skin irritation or redness | Rare | Generally well tolerated; mild irritation occasionally reported in sensitive individuals. |
| Allergic contact dermatitis | Very rare | Isolated reports; possible in those sensitized to plant-derived polysaccharides. |
