Healthy skin has the ability to bot

Healthy skin has the ability to both produce and destroy or weaken collagen and other molecules in the ECM. But why would the body want to destroy something as important as collagen? Think of a complex city that’s constantly growing and changing — sometimes you build new areas, and sometimes you have to take down old, rundown buildings to make room for something better. It’s the same way with the ECM-breaking enzymes, or MMPs. They are the body’s way of clearing out whatever is in the way of creating something better and stronger.
