What is Tallow? Tallow is a rendered fat, usually beef fat that surrounds the cow's organs. It has been used for centuries in skin care. Tallow is a very healthy fat that contains a wide array of all the beneficial nutrients that our skin needs to repair itself. It is the best moisturizer to use if you want healthy skin. Many of the nutrients in grass-fed/finished tallow help to promote youthful skin by providing substances that our skin naturally loses as we age. Tallow is extremely compatible with the oil that our skin naturally produces. Compared to plant-based oils, Tallow provides skin with very intense moisture. You will recognize this immediately when you put it on your skin. There is nothing better than tallow for soothing and hydrating dry skin. Tallow is not only great for repairing skin, but it also helps to prevent damage to skin. All of those skin-friendly antioxidants and other nutrients keep skin healthy and strong.
