Allantoin is a byproduct of uric acid that can be extracted from urea and is the result of metabolic processes that occur in most organisms – among them animals (including humans) and bacteria. It can also be extracted from comfrey (taken from the roots and leaves) and is proven safe and effective because it does not contain the potentially irritating alkaloid compounds that occur in the comfrey plant.
Occurs naturally in most organisms but can be produced synthetically
Has both soothing and moisturizing properties for skin
Helps mitigate skin’s response to more active ingredients
