Protecting your skin from the sun's ultraviolet (UV) rays is one of the best ways to prevent premature aging. Look for a broad-spectrum sunscreen with an SPF of 25 to 30 for the best protection against both ultraviolet A (UVA) and ultraviolet B (UVB) radiation. For those among us who want a little more from their sunscreen, some sunscreens contain skin-strengthening, collagen-regenerating ingredients such as vitamin E and soy isoflavones. Find the right sunscreen for you, and apply generously throughout the day.
And while sunscreen will help prevent premature wrinkling from the sun's UV rays, moisturizer can help reduce the appearance of wrinkles you may already have. Moisturizers have skin-plumping properties and temporarily fill in wrinkles with moisture (and some with proteins such as collagen or keratin) while improving the overall health of your skin.
