Silicone gel sheets are flexible, adhesive strips made from medical-grade silicone. They are commonly used to improve the appearance of scars by hydrating the skin and creating a protective barrier. These sheets can be applied directly to the scar and are often recommended for both new and old scars. The use of silicone gel sheets is supported by various studies that suggest they can help flatten and soften raised scars, such as keloids and hypertrophic scars. They are easy to use, typically worn for several hours a day, and can be cut to fit different scar sizes and shapes.
