Sunscreen

Sunscreen: It's a must, essential for preventing sun damage and lowering your risk of developing skin cancer. Many skin care lines have facial moisturizers with SPF already included; they offer a more luxurious, makeup-friendly texture than traditional sunscreens. If you use only one product, sunscreen should be it. A lotion like Neutrogena's Healthy Skin Lotion with SPF 15 moisturizes, protects with SPF, and smoothes skin with alpha-hydroxy acids (AHAs) and vitamin C -- practically the perfect all-purpose face lotion.
