Skin Care and Protection

Why is skin care and protection important?

Your skin changes as you age. It becomes thinner and begins to sag, causing wrinkles. It gets injured more easily and heals more slowly. The older you get, the more important it is to take care of your skin. Common complaints as people get older include dry and itchy skin, wrinkles, sagging skin, color changes, and "age spots." Even more worrisome, however, is the possibility that some of those age spots may turn out to be skin cancer.

There are things you can do to help some skin problems, like dryness and itching. Also, if you keep your body healthy with good nutrition and enough exercise and rest, you will look and feel younger. You are never too old to take care of your skin. And you are never too old to protect your skin from damage caused by the sun's ultraviolet rays.

What causes dryness and itching?

Dry skin, which can cause itching, is very common as you get older. Your skin has fewer sweat and oil glands than when you were younger. Frequent baths and showers, especially with harsh soaps, can make your skin even drier. Your skin may be irritated by some cosmetics or fabrics. Medicines may cause dryness or itchiness.

What happens from too much exposure to sunlight?

While some exposure to sunshine is necessary for the body to make vitamin D, too much exposure can be damaging to your skin. Sun damage shows first in the form of freckles, followed by roughness, age spots, wrinkles, and sometimes cancer. Fair skin burns more easily than tanned or darker skin, but dark skin will burn, too. Some of the skin changes associated with age are partly due to ultraviolet radiation (UVR) exposure. The closer you are to the sun (for example, living near the equator or at high altitudes), the more exposure to UVR you experience. Damaged skin can repair itself to some extent if further UVR exposure is avoided, so it is worth protecting your skin from too much sun at any age.

The symptoms of sun damage are:

• freckles, "age spots," or moles that suddenly appear, grow, or change color
• dry, rough skin or wrinkling
• small blood vessels showing as red lines on the cheeks, nose, and ears.

You are most at risk of sun damage to your skin if you:

• have fair skin that freckles and burns easily
• live near the equator or at a high altitude
• spend a lot of time working or playing outdoors
• sunbathe.

Too much UVR exposure can lead to skin cancer. The most common skin cancers are basal and squamous cell cancer. These cancers can usually be removed successfully if caught early. Malignant melanoma, a less common but more dangerous skin cancer, is 10 times more common today than 60 years ago. Research suggests that malignant melanoma in adults may be related to sunburn in childhood.

How can I take care of myself?

Whatever the cause of dry skin, there are things you can do about it. You may need to moisturize your skin at least twice a day. Avoid perfumed lotions because the perfume may irritate dry skin.

• Take fewer showers or baths. Bathing just 2 or 3 times a week is enough. Keep your baths and showers short, and use warm, not hot, water.
• Use soaps made for dry skin, such as glycerin soap with cleansing cream, and rinse well.
• Put a moisturizing skin lotion over your whole body after you pat yourself dry with a towel. Put more lotion on dry areas throughout the day.
• Wear cotton next to your skin. Wool can irritate dry skin and make itching worse.
• Always shower and use lotion right away after you swim in a chlorinated pool or sit in a hot tub.
• Avoid saunas.
• Consider using a humidifier on cold, dry winter days.
• Drink plenty of fluids throughout the day.
• Try to stay out of the sun between 10 AM and 2 PM. Avoid getting a lot of sun and UV exposure, including tanning salons.
• When you are out in the sun, cover your skin with light, loose clothing. Wear a wide-brimmed hat and sunglasses, and use a sunscreen with an SPF (sun protection factor) of at least 15.
• Check your skin regularly for new moles or moles that grow or change color. See your healthcare provider if you notice new or unusual changes in your skin.
• If medicines are causing a dry skin problem, talk to your healthcare provider about alternatives.
