The roots of the lush green Comfrey plant (Symphytum Officinale) which is native to the United States and Europe contain a powerful substance called Allantoin. Allantoin is found within the root mucilage that the comfrey produces, and accelerates new skin cell growth while also being a natural anti-inflammatory agent. The Comfrey Extract contains many beneficial compounds to assist in anti aging and revive tired skin, as well as combating conditions such as eczema, psoriasis, burns, cuts and dermatitis due to its anti inflammatory properties.
Allantoin has the ability to act as an emollient, that helps develop a protective film over skin cells which leads to less water loss. Allantoin also acts as a keratinolytic which soften the keratin protein found in the outer layer of the skin, allowing the skin to hold onto water better. This makes it moister, more supple, and extremely hydrated. Keratinolytics also promote shedding of the skin which results in visibly smoother and improved skin texture.
