Shea butter is extracted from the seeds of the wild shea tree in West Africa. This butter has moisturizing and healing properties. Refining is usually done with a chemical called "hexane". Certified organic means that the butter is filtered using clay and no toxic chemicals. African women have been using this oil for generations to protect their skin from the harsh dry climate.
Cocoa butter is the fat extracted from the cacao bean. It is a natural emollient and contains natural antioxidants and actually helps to increase skin hydration.
