#comfrey extract
- Allantoin — An organic compound with the chemical formula C4H6N4O3, resulting from the oxidation of uric acid in purine metabolism in most mammals (except higher primates and humans) or extracted from plants such as comfrey (Symphytum officinale); an active substance structurally recognized for its keratolytic, healing, anti-irritant, and intense moisturizing properties. Due to its capacity to stimulate cell proliferation and rapid regeneration of skin tissues, it is widely used in the dermatocosmetic industry for formulating creams, lotions, and ointments intended for sensitive or damaged skin.
