What Is Allantoin?
Allantoin is a gentle, skin-conditioning ingredient recognised for its soothing and moisture-supporting properties. It's often included in formulas designed for sensitive, post-treatment or easily irritated skin, where a calm, comfortable finish matters as much as the active ingredients.
Across ASI's body and after-care formulas, allantoin works alongside botanicals like witch hazel and tea tree to round out a soothing, non-irritating finish.
