Olive oil has been a staple beauty ingredient in Italy for centuries. Women have used it for skin and hair care extensively. Olive oil forms a breathable layer on the skin to prevent loss of internal moisture, but it does not block the natural functions of the skin and takes a little longer to penetrate. Skin will continue to sweat, release sebum and shed dead skin cells. Suggested Usage: in cold process soap up to 100% of your base oils, however, bars will need to set much longer to harden when larger quantities of this oil are used. Lotions and creams - 3% to 6%; balms and butter sticks - 5% to 100%.
