Using this insulin pump skin is a breeze. First, make sure your insulin pump is clean and dry. Then, carefully peel the backing off the skin and align it with your pump. Slowly apply it, smoothing out any air bubbles as you go. When it comes to maintenance, just use a soft, damp cloth to gently wipe the skin if it gets dirty. Avoid using harsh chemicals as they might damage the vinyl. Also, keep in mind that this purchase doesn't include the insulin pump itself. If you have any issues with the fit or application, don't hesitate to reach out for help.
