As we get older, two things affect the appearance of our skin. One is our genetics and the other is the environment. The aging of our skin begins in our 20's when the body slows the production of new skin cells and produces less collagen and elastin, which are the proteins that give skin its elasticity. Evidence of these changes does not show u and and and and and and and and p right away but later in life we start to see tiny lines, and our skin begins to thin and become more dry. After age 50, many of us will begin to see ?age spots?, or ?liver spots?. These are the large brown, freckle-like spots that appear on the hands or arms.

Sun protection

The number one environmental cause of aging skin is exposure to sunlight. The sun's ultraviolet rays are harmful to the skin. Frequent sunbathing and long-term exposure to sunlight actually causes skin damage. The results are dry skin, wrinkles, and in some cases, skin cancer.

Avoid long periods of sun exposure if possible but if you know you are going to have to be outside for a long time, wear clothing that protects your skin from potential sun damage. Wear shirts with long sleeves, slacks, and sun hats with a brim wide enough to protect your face. Limit your time outside during the hours of 10 a.m. to 4 p.m. because this is the time when the suns rays are the most damaging.

Choose a sunscreen that has a sun protection factor or SPF of 15 or higher, and apply it 20 minutes before being exposed to the sun. Remember to reapply it after getting out of the pool or after doing any exercise that caused you to perspire.

Skin care

A daily cleansing and moisturizing regime is important for skin care. Avoid long hot baths or showers as they can dry out your skin. Use a mild soap that does not excessively dry your skin. Perfumes or dies, can irritate sensitive skin, so avoid these when choosing your cleanser. Always remove makeup completely and do not go to bed with makeup on. Do not pull the skin when drying your face, just gently pat your skin dry.

Moisturize after cleaning your skin. Select a moisturizer with an SPF of at least 15 to provide extra sun protection. Apply a moisturizer before your skin is completely dry to help lock in extra moisture. Choose a lotion that is free of perfumes or dies to avoid irritating your skin.

Nutrition

Choose foods that will contribute to healthy skin. Vitamins A and B can contribute to healthy looking hair, skin and nails. Vitamins C and E can help protect the body from the damage of free radicals and help to protect skin from the damaging effects of the sun. The best way to ensure that you are getting all of the necessary nutrients for healthy skin is to eat a variety of foods from the USDA food pyramid.

While we cannot change the genetic aspects of normal aging, there are many measures we can take to help keep our skin looking healthy. By protecting ourselves from the sun, practicing daily skincare and eating a balanced diet, we can look forward to healthier looking skin into old age.
