Scars are an integral part of the healing process and result from an overproduction of collagen at the wound site. Scars go through numerous changes as they mature, but they are permanent in nature. Bio-Oil is formulated to help improve the appearance of scars, but it can never remove them. Usage instructions: Bio-Oil should be massaged in a circular motion into the scar, twice daily, for a minimum of 3 months. On new scars, Bio-Oil should be applied only once the wound has healed, and should not be used on broken skin. Results will vary from individual to individual.
