Use a broad-spectrum sunscreen that protects against UVA and UVB rays and has a Sun Protection Factor of 15 or greater, even on cloudy days. Buy a non-stinging product or one specially formulated for use on faces if you're using it on your face or your children. Buy a PABA-free brand if you are sensitive to that sunscreen ingredient. Reapply sunscreen every two hours when outdoors, especially if you're swimming or sweating. Wear protective, tightly woven clothing.
Dark colors give more protection.
Stay in the shade whenever possible. Avoid reflective surfaces, that can reflect up to 85 percent of the sun's damaging rays. More expensive sunscreen is not better. Although a costly brand may feel or smell better, it isn't necessarily more effective. Babies under 6 months old should spend very little time in the sun.
