Unrefined shea butter contains an abundance of beneficial ingredients, including vitamins, minerals, proteins and a unique fatty acid profile, and is a superior active moisturizer. Unlike petroleum based moisturizers, shea butter actually restores the skin's natural elasticity. Shea butter enables your skin to absorb moisture from the air, and as a result, it becomes softer and stays moisturized f
or longer. It is most effective when applied to the skin in its pure state. Regular users of pure, unrefined shea butter notice softer, smoother, healthier skin. Shea butter has also been shown to help moisturize dry skin and reduce the appearance of fine lines and wrinkles. Most shea butter available to the general public outside West Africa is white and odorless, in other words it has been "refined" to remove the natural scent and color of natural shea butter. In the process, the majority of the effective agents are also removed. In addition, refined shea butter has usually been extracted from the shea kernels with hexane or other petroleum solvents. The extracted oil is boiled to drive off the toxic solvents, and then refined, bleached, and deodorized, which involves heating it to over 400¡F and the use of harsh chemicals, such as sodium hydroxide. Shea butter extracted in this manner still contains some undesirable solvent residues, and its healing values are significantly reduced. Antioxidants or preservatives such as BHA (butylated hydroxyanisole) or BHT (butylated hydroxytoluene) may be added as well.
