While wrinkles are inevitable for everyone, there are steps you can take to delay their appearance. Your first line of defense is to avoid too much sun exposure. That involves applying sunscreen before stepping outdoors, even when you're out doing routine activities like picking up your laundry or shopping. Choose a sunscreen that blocks both UVA and UVB rays and has an SPF of at least 15. Also, be sure to reapply your sunscreen every few hours [source: Mayo Clinic].
Keep in mind, however, that although avoiding the sun helps prevent wrinkles, it doesn't mean you should take shelter in a cave. A lack of sunlight can lead to other problems, including vitamin D deficiency. The body produces vitamin D when sunlight hits your skin. Approximately 50 to 75 percent of Americans don't get the vitamin D they need, and some experts believe that a lack of sun exposure can contribute to the problem [source: Roan]. Vitamin D deficiency leads to bone and muscle problems, and some forms of cancer. It can also contribute to diabetes, depression and high blood pressure.
Simply adopting healthy habits can also help you keep your skin looking young. Try reducing stress and avoid smoking. Exercising regularly can benefit your skin as well as your muscles. In addition, use a good skin moisturizer, and eat a diet filled with fruits and vegetables and plenty of water. Salmon, soy and cocoa are also beneficial in improving the skin's structure [source: WebMD].To keep wrinkles from forming, try sleeping on your back, and use sunglasses in bright sunlight so you won't squint.
But as time marches on, you will eventually see wrinkles beginning to form. If some of the previous steps aren't working too well, however, there are some treatments you can research that might reduce the appearance of wrinkles.
