The ecosystem and skin interact in many different ways. The sun can burn, give you cancer, or tan your skin because of the UV rays. There are many other abiotic factors that can effect your skin. Wind can give you wind burn, humidity can affect the moisture in your skin, and factors in the ecosystem such as twigs and rocks can cause incisions in your skin.
That was just the abiotic factors in a ecosystem, there are hundreds of living things that also effect someones skin. For example, every ecosystem in the world has bacteria, fungi and even viruses, and to defend against the pathogens the skin must do a number of things. The top layer of skin, epidermis, will shed so that all of the pathogens on the skin will be cleared off. Once the skin has shed a new layer of epidermis will grow and that brings me to my next point. If the skin does break then there is a free ride for all of the pathogens into the body. Because the skin is the first line of protection from pathogens it must heal.
Also, the glucose and oxygen from the ecosystem provide the necessary ingredients for the skin cells to go through cell respiration.
This skin diagram shows where the epidermis layer of the skin is that sheds to clear away pathogens.
