Bio-Oil successfully combines the well-documented benefits of two important skincare disciplines–natural plant oils, used for centuries to enhance the skin’s condition, and vitamins, a vital element in the promotion of healthy-looking skin. The natural plant oils and vitamins are mixed in an oil base. This allows the formulation to be oxygen-free, which helps to ensure that the natural plant oils and vitamins maintain their maximum potency prior to application. Purcellin Oil, Bio-Oil’s breakthrough ingredient , is then added to the mix. Purcellin Oil reduces the consistency of Bio-Oil, making it a rapidly absorbed “dry” oil that delivers the natural plant oils and vitamins into the skin where they are most needed. Without this breakthrough ingredient, the natural plant oils and vitamins would remain on the skins surface as an oily residue, instead of being quickly absorbed.
