Allantoin is a natural chemical compound, found in the comfrey plant extract but it can also be obtained synthetically. Allantoin has a naturally soothing and healing action, which increases the water content in the extracellular matrix, strengthening the cells’ structure. It also moisturizes and smoothes the skin, and promotes cell regeneration for faster healing of wounds and scars. Furthermore, it is odourless, non-toxic and hypoallergenic both in its synthetic and natural form, making it suitable for people with sensitive skin, rosacea or eczema.
