Allantoin
Allantoin is a gentle, non-irritating compound used in skincare for its soothing, healing, and skin-protectant properties. It accelerates cell proliferation and promotes wound healing by stimulating fibroblast activity and extracellular matrix synthesis. At the same time, it softens keratin in the stratum corneum, providing a mild keratolytic (exfoliating) effect that smooths rough skin. The FDA recognizes allantoin as an approved skin protectant active ingredient. It is exceptionally well-tolerated, making it valuable for sensitive, irritated, and post-procedure skin where stronger actives cannot be used. You will find allantoin in healing ointments, sensitive skin moisturizers, lip balms, and after-sun products.
How Allantoin Works
Allantoin promotes cell proliferation by stimulating fibroblast growth factor. It softens keratin through desquamation, helping shed dead cells gently. It also has anti-irritant properties that soothe inflammation and moisturizing effects through increased water content in the extracellular matrix. FDA-approved as a skin protectant at 0.5 to 2 percent concentration.
