Allantoin is a soothing agent which helps to reduce redness and promotes cell generation. It can support wound healing and improve skin texture. Allantoin can be found (in large amounts) in comfrey plants and (in smaller amounts) in plants such as chamomile or sugar beets. In skin care products the synthetic version of allantoin is mostly used. Why? Because it can be produced in large quantities, without impurities and allergens that are present in the natural compound can be removed.
