A new treatment for hypertrophic scars from burns, surgeries and trauma combines the advantages of both traditional pressure pads and silicone gel sheets. The Smart Scar-Care pad designed at The Hong Kong Polytechnic University serves the dual functions of reinforcing pressure and occlusion.

Pressure therapy is the first-line non-invasive treatment for hypertrophic scars. Pressure garments and pressure pads made with polyethylene foam are generally used but are uncomfortable to wear and often unable to maintain pressure on the scar. Commercial silicone gel products are also used to treat hypertrophic scars but primarily just moisturize the affected area.The pad combines the effects of pressure therapy and silicone gel on scar management.

The Smart Scar-Care pad is composed of silicone stiffener and medical grade silicone gel sheet. The smooth side is attached to the silicone gel sheet, which serves to moisturize the scar. The other side of the silicone stiffener features circular silicone studs that could easily be adjusted to shape the curved or flat skin surfaces to provide even pressure under elastic bandages or pressure garments.

Different stud heights, diameters and gel thicknesses support treatment of varying wound geometries. If applied to flat or concave areas, such as the chest or abdomen, higher studs are used to create a larger curvature. Thicker gel sheets may be applied to thicker scars, and conversely, thinner gel sheets to thinner scars.

Clinical trials confirmed good performance in reducing pigmentation and vascularity, improving elasticity, and preventing dehydration. The innovative design earned the Grand Award and Gold Medal with the Congratulations of Jury at the 45th International Exhibition of Inventions of Geneva, 2017.
