What It Does
Allantoin is a white, odorless crystalline powder naturally found in comfrey root and botanical extracts, though commercially produced through urea oxidation. It's renowned for its keratolytic properties that promote cell proliferation and wound healing, while simultaneously soothing irritated skin and enhancing moisture retention. Formulators favor allantoin for its exceptional tolerance across all skin types, its stability in various pH ranges, and its ability to improve skin texture without causing sensitization, making it a staple in post-procedure, sensitive skin, and anti-aging formulations.
