Protecting skin from harsh sun rays is one of the most important anti-aging techniques for women. When planning your skin care regimen, look for moisturizers and makeup that contain UV protection. If you plan to be in the sun for an extended period of time, you should re-apply your sunscreen every 2-3 hours. Wide-brimmed hats provide an extra level of defense.

Many women don't realize that squinting in the sun can also cause wrinkles. Wearing sunglasses during the brightest parts of the day can help to prevent the furrows that can form around the eyes from squinting. This anti-aging tip has another benefit, too: sunglasses have been linked to the prevention of cataracts later in life.
