Allantoin is widely used in skincare products due to its soothing and healing properties. It helps to promote cell regeneration, making it effective in treating dry, irritated, or damaged skin. It is commonly found in moisturizers, lotions, and creams designed for sensitive skin or conditions like eczema and psoriasis. Additionally, allantoin is used in cosmetic formulations to improve the texture and appearance of the skin by providing a smooth, soft feel. It also acts as a keratolytic agent, aiding in the removal of dead skin cells and enhancing skin renewal. In hair care products, it helps to strengthen and protect hair, reducing breakage and improving overall hair health. Its anti-inflammatory properties make it a valuable ingredient in after-sun products and treatments for minor skin irritations.
