Galactoarabinan is a plant-based sugar derived from trees. The film-forming agent can be found in certified organic products, depending on where the ingredients are sourced.
While galactoarabinan is commonly known to support moisture retention, the ingredient is used in many astringents and toners as well. For this reason, sometimes galactoarabinan is referred to as an exfoliating product. This property is usually due to the ingredient’s ability to enhance the effectiveness of exfoliating formulas when it is combined with other ingredients.
