Hello, I have a question. How long does it take for an inflated skin to not stretch back and new cells to grow? Is there a general formula which will allow you to calculate how much extra skin will be generated with the given inflation time and the baloon volume aka pull/push force?Also, what will happen if the skin is only inflated about 10 hours each day? Will that cause skin expansion or will the skin always go to its original form during rest of the day?
