Whether it's a car accident, surgery, or another type of injury, many of life's unfortunate events leave their marks as scars. While almost everyone has one or more scars that remind them of such situations, some scars can be more critical than others. In addition to possible physical pain and discomfort, there can be psychological impairment and reduced self-confidence, especially when scars are located on visible parts of the body. Hansaplast Scar Reduction is a transparent, self-adhesive polyurethane patch. Products made from this material have been used in professional wound care for years. The patches contain no active ingredients that could cause side effects. They are a safe and effective way to significantly reduce raised and discolored hypertrophic scars or keloid scars.
