Abstract: A scar treatment silicone dressing used for attaching onto wound of skin, comprising: a surface layer, a connection layer, a silicone layer, and a protection film. The surface layer is moisture permeable and water resistant thus providing protection function, and on one of its sides is disposed a silicone layer through a connection layer. The silicone layer is provided with penetrating through holes for controlling dissipation of moisture of skin wounds, as such assisting skin exiting perspiration to said surface layer via said through holes, hereby reducing the possibility that the acidic metabolite in perspiration getting in touch with the skin for long period of time in causing irritations/inflammations of the skin; meanwhile, it is also capable of preventing over-dissipation of moisture from the surface of skin, thus it will not adversely affect the repair and reconstruction of the scar tissue.
