Many things can cause skin aging. Some we can’t change and some we can. One of the things that cannot be changed is the fact that aging is a natural process. With time, all of us develop wrinkles on our faces. Our skin becomes thinner and drier. Our genes control when changes occur. Medical students, we call this “natural aging”. Some we can change. Our environment and lifestyle choices can cause our skin to age prematurely. The medical term for this is “exogenous aging”. With some preventive measures, we can slow down the aging of our skin.
