Bio Oil helps improve the appearance of both new and old scars. It also helps reduce the possibility of stretch marks forming during pregnancy, teenage growth spurts and periods of rapid weight gain, and helps improve the appearance of existing stretch marks. Bio Oil is great for improving the appearance of uneven skin tone in both light and dark skin types. It is used for smoothing and toning ageing and wrinkled skin on both the face and body, and helps retain moisture. It contains the breakthrough ingredient PurCellin Oil, which reduces the thickness of the formulation and makes it easily absorbed.
