The most important additive in a daily facial moisturizer is sunscreen. The ultraviolet rays (UVA and UVB) from the sun rob the skin of hydration, leading to wrinkles, skin damage and possibly cancer. By applying a face lotion with sunscreen in it, you can protect your skin from premature signs of aging and maintain a healthier appearance. Dermatologists generally recommend a moisturizer with at least an SPF 15 to adequately safeguard against the sun. If you're out in direct sunlight for an extended amount of time, the American Academy of Dermatologists also advises reapplying sunscreen every two hours.
