The application of silicone materials is being tested in the treatment of hypertrophic scars and keloids. Application to hypertrophic scars is useful for involution, and the involvement of negative charge generation has been suggested. We conducted a comparative investigation of the differences in negative charge generation values due to different shapes of silicone materials. The materials used were silicone cushion with a high-viscosity silicone oil enclosed in the silicone capsule, silicone gel sheet and silicone cream. Negative charge was measured using an electrostatic potential meter (JNM-ECA500) and the measurement values examined comparatively. Generation of negative charge was highest with silicone cushion, followed by silicone gel sheet, and silicone cream. Silicone cushion is designed to generate a static electric field of a structural negative charge, and the generation of significantly strong negative potential was measured.
