There are many different causes for dark dry skin, including basic skin problems to more serious medical conditions. The three main factors that can contribute to this type of condition are diseases and medical conditions,
changes in the skin, and exposure to the sun. Even though all of these factors result in the same effect, which is darkened dry skin, the actual effects of them can be extremely different. The medical problems that can cause this change in skin pigment can be serious at times, so if numerous spots or sections of the skin begin to change color it is suggested that a licensed medical practitioner be consulted so some tests can be conducted.
The first factor that will cause a change in skin color is simply from having exposure to the sun. The rays from the sun cause the skin to change color in an effort to defend itself from ultraviolet rays. Extreme levels of sun exposure can cause more permanent damage to skin and may increase the risk of developing skin cancer.
Basic changes to the skin can also be a cause for dark dry skin. As humans age, their bodies change, including how the pigments in the skin are produced. This can cause dark blotches all over the body and is no reason for concern because it is normal in most cases. However, changes in color can also occur due to poor skin health, as well as constant friction. These conditions can usually be reversed by taking better care of the skin and being more aware of what actions are taken during the day.
The final factors that can cause these problems are medically related. For instance, various skin diseases such as psoriasis, eczema, and dermatitis can cause dark dry skin. Dark dry circular spots, medically known as hyperpigmentation, can be caused by these medical conditions, as can white spots forming on people with darker skin. Inflammation and medications can also cause the same effects within the skin, so when a medical condition is the reason for the problem, a medical professional should be consulted in order to isolate the problem
