PolyU Designs Innovative “Smart Scar-Care” Pad to Create a “Scar-Less” World

The “Smart Scar-Care” pad designed by Professor Cecilia Li-Tsang in the Department of Rehabilitation Sciences, PolyU, serves the dual functions of reinforcing pressure and occlusion.

An innovative “Smart Scar-Care” pad which serves the dual functions of reinforcing pressure and occlusion has been designed by The Hong Kong Polytechnic University (PolyU) to treat hypertrophic scars from burns, surgeries and trauma. Compared with the traditional pressure pads and silicone gel sheets, “Smart Scar-Care” pad has the advantages of both.

It showed good performance in reducing pigmentation and vascularity, improving elasticity and preventing dehydration in a clinical trial. It is more durable and user-friendly compared with the traditional pad (polyethylene foam) as reported by the patients. This innovative design has won the Grand Award and Gold Medal with the Congratulations of Jury at the 45th International Exhibition of Inventions of Geneva, 2017.

Burns, surgeries and trauma will create open wounds to the human skin. Delayed wound healing can result in formation of hypertrophic scar, which will cause aesthetic problems, and induce severe deformities, thus causing dysfunctions. Pressure therapy is the first line non-invasive treatment for hypertrophic scars. Pressure garment and pressure pads made with polyethylene foam are generally used by the local therapists. However, they are uncomfortable to wear and often non-durable to sustain the pressure on the scar. The commercial silicone gel products are used to manage hypertrophic scar but they could mainly moisturize the hypertrophic scar.
