Shea butter is a natural moisturizing ingredient derived from the nut of the African shea tree. It is widely used in cosmetics and skin care products due to its high concentration of fatty acids and vitamins, which help to nourish and protect the skin. Shea butter has been used for centuries in Africa as a remedy for dry skin, eczema, and other skin conditions. It is also known to have anti-inflammatory properties, making it an ideal choice for those with sensitive skin.
