It is derived from the roots of the comfrey plant and has been used for centuries to promote skin health. Allantoin helps to moisturize and exfoliate the skin, while also reducing inflammation and promoting the growth of new tissue. It is often used to treat skin conditions such as acne, eczema, and psoriasis. If you're looking for a gentle and effective ingredient to add to your skincare routine, allantoin may be just what you need.
