Sanfe Silicone Scar Sheet is a soft, flexible, self-adhesive dressing that is applied over scars. It contains silicone which helps to improve the colour, height and texture of a scar. It will also relieve itching and discomfort caused by a scar. How does it work? Silicone creates a protective barrier over the scar which allows it to mature while helping to prevent production of excess scar tissue. The silicone layer also assists with hydration of the scar. This moist environment promotes the regulation of collagen production, which is essential for proper wound healing and scar formation. Furthermore, silicone has been shown to normalize pigmentation and improve the overall appearance of scars. For new scars, results will be visible within 6 weeks and older scars take time upto 3 months. Recovery time will vary depending upon the size and severity of the scar. If you do not see result in desired span of time, please do not discontinue the use.
