Oil based makeup removers typically use a combination of oils which can help to break down the waxes and long-wearing ingredients often used in waterproof makeup. Water based makeup removers often have water as one of their key ingredients and give a refreshing cleanse to the skin – they may also take the form of a micellar water makeup remover. Our Bi-Facil Eye Makeup Remover uses a combination of both oil-based makeup removers and water-based makeup removers also known as Bi-Phase technology.
