Allantoin is a naturally ocurring nitrogenous compound used as a skin conditioning agent.

Ingredient functions - The main function of allantoin in skin care is to promote skin cell regeneration and exfoliation. It helps to remove dead skin cells, allowing for the growth of new, healthy cells. This leads to smoother, softer, and more youthful-looking skin.

Concerns - Allantoin is generally considered safe for use in skin care products. It is non-toxic and non-allergenic, making it suitable for most skin types. However, as with any ingredient, some individuals may be sensitive or allergic to allantoin. It is always recommended to perform a patch test before using a product containing allantoin for the first time. There are no known major concerns or restrictions around the use of allantoin in skin care and beauty products. However, it is important to use products containing allantoin as directed and avoid excessive use, as this could potentially cause skin irritation
