Allantoin
What is Allantoin?
Allantoin is a white, odorless crystalline powder, chemically known as 5-ureidohydantoin, derived synthetically from glyoxylic acid or extracted from botanical sources like comfrey root and wheat sprouts. In cosmetics, it belongs to the category of skin conditioning and soothing agents, commonly incorporated into creams, lotions, gels, and aftershaves at low levels. It functions by forming a hydrating film on the skin's surface to lock in moisture, mildly exfoliating dead cells to promote smoother texture, and interacting with skin proteins to enhance barrier integrity against daily environmental stressors. This multi-action mechanism helps maintain skin comfort without greasiness, making it versatile across product formulations for everyday use.
