The tension-reducing tape directly attached to the wound will not affect the wound. Tension reducing adhesive tape is a good helper to prevent scar hyperplasia after skin surgery or trauma. In some joints or faces that are not suitable for wearing tensioners, tension-reducing adhesive tapes are often used instead of tensioners to inhibit scar hyperplasia. The principle of tension-reducing adhesive tape is to reduce the tension of skin on both sides of the wound through the tension of adhesive tape, so that the scar will be narrower after the wound heals in the later stage and prevent the scar from expanding. At the same time, it is necessary to inhibit the proliferation of scar protrusions. It should be noted that when there is infection or other skin lesions in the adhesive area, the tension reducing band cannot be used. In addition, the tension reducing belt should not be attached too tightly to avoid complications such as tension blisters.
