24 hours later / Discoloration bandage

24 hours later

Very often, we paste a plaster for so long time that we forget to get it replaced. As a result, the skin area under the plaster may become white for lack of air or even be bothered by bacteria. This new type of plaster is designed with an additional indication layer made of iron element which is attached to the upper surface of plaster. The plaster will change its color from white to yellow and then to red with the time gone by for the iron element can change its color in air. Tuning the changing period at 24 hours, people will notice the time to replace the plaster when it becomes red.
