As you age, you may at first notice subtle changes in your skin. In a way, it will reflect upon how you and the environment have treated your skin, as well as any genetics that can influence how your skin appears. Some changes are inevitable as processes within your body change. Understanding how your body ages can help you identify the differences in your skin and perhaps ways to counteract the effects.
Causes
One of the primary causes of changes in your aging skin is the environment. If you have spent a lifetime in the sun or in harsh weather conditions, your skin may show these ill effects. According to the Milton S. Hershey Medical Center, the effects of aging tend to be more visible if you have experienced sun damage on your skin.
Epidermis Changes
You are likely to notice the effects of changes in your epidermis or outer skin layer. Your skin may appear thinner and have a rough surface. Your epidermis acts as a protective layer, guarding you against disease-causing micro-organisms and harmful environmental effects. As it becomes thinner, your skin becomes more vulnerable to bruising and injury. Your inner blood vessels will also age, becoming more fragile. As a consequence, you may find that wounds healer slower or that you bruise more easily. According to the National Institutes of Health's Medline Plus website, it may take your body up to four times longer to repair wounds.
Formation of Wrinkles
One of the most obvious effects of aging is the formation of wrinkles. Genetic factors may predispose you to wrinkles. They occur as the collagen within your skin weakens. The loss of support of this protein accounts for the loose appearance of your skin. In addition, the layer of subcutaneous fat under your skin will begin to thin, contributing to the formation of wrinkles.
Other Effects
Your skin may take on a dry look as oil glands produce less oil. This can cause your skin to become itchy and make your uncomfortable. You may find that your discomfort increases during the winter when you are in dry, indoor conditions. Skin care is more important than ever as you should avoid harsh soaps or frequent hot baths which can exacerbate your symptoms.
Prevention/Solution
While aging skin is inevitable, there are several things you can do now to minimize some of the effects. You should limit your time in the sun during the peak hours of 10 a.m. to 2 p.m. to avoid the most damaging rays. If you must be outside, always wear a sunscreen with an SPF of at least 30. The American Academy of Dermatology recommends that you use at least one ounce of sunscreen to cover your body. As you age, you may become more vulnerable to skin damage. Therefore, as part of your annual exam, make sure your doctor examines your skin carefully, especially if you have detected sudden changes in your skin's appearance.
