a composition is formed by the step of feeding a molecule that has an active oxygen - forming species into a silicone based polymer . the silicone - based polymer is substantially free of pendant groups that are reactive with active oxygen species . silicone - based polymers have proven scar - healing properties . as such , the composition is useful for treating skin disorders , especially scars , to reduce the appearance of the scars . furthermore , bacteria and infections may contribute to the formation of scars . the active oxygen - forming species form active oxygen species , which oxidize pathogens including bacteria , viruses , and fungus to sterilize an area in contact with the composition . as a result , the appearance of scars treated with the composition may be even further reduced due to the presence of the molecule having the active oxygen - forming species .
