Introduction to Allantoin

Allantoin is a naturally occurring diureide of glyoxylic acid, found in plants like comfrey, chamomile, and sugar beet, as well as in the urine of mammals. It is widely recognized for its skin-soothing, moisturizing, keratolytic, and wound-healing properties. Commonly used as a ?skin protectant,? allantoin promotes cell regeneration, enhances hydration, and softens rough or dry skin. Because of its gentle and non-irritating profile, it is included in numerous cosmetic, dermatologic, and pharmaceutical preparations such as creams, gels, lotions, and ointments for sensitive or damaged skin. This guide provides an in-depth look at allantoin, including its uses, dosage, potential side effects, interactions with other medications, and frequently asked questions.
