In personal care

A compound found naturally in comfrey root and also made synthetically for cosmetic use. It is a small, water-soluble molecule known for calming and softening effects on skin.

Why it’s used

Formulators add it to soothe irritation, support the skin's barrier, and help with mild exfoliation by softening the outer layer of skin cells. It is common in products aimed at sensitive or compromised skin.

What the evidence says

The CIR Expert Panel's safety assessment concluded that available test data were sufficient to support the safety of allantoin and its related complexes at the concentrations used in cosmetics, with allantoin itself used up to 2% in over 1,300 products. The abstract does not describe specific adverse findings or mechanisms of concern. It notes data gaps for two minor allantoin complexes (galacturonic acid and polygalacturonic acid), but these do not apply to allantoin itself.

Context

Used across rinse-off and leave-on products alike, generally at low concentrations (0.1–2%) where its main role is calming rather than active treatment.
