The Body Shop difference: Tea Tree Oil can be used in many different ways to help soothe blemished skin. Dab pre-blended oil directly onto skin at first sign of a blemish. Apply a small amount directly onto blemishes using a clean cotton wool bud or your fingertip. For bathing, add six drops into the bath once it has run, and disperse with your hand, for an aromatic and soothing soak.
