To help avoid age spots, follow these tips for limiting your sun exposure:
- Avoid the sun between 10 a.m. and 4 p.m. Because the sun's rays are most intense during this time, try to schedule outdoor activities for other times of the day.
- Use sunscreen. Fifteen to 30 minutes before going outdoors, apply a broad-spectrum sunscreen that provides protection from both UVA and UVB light. Broad-spectrum sunscreens contain one or more of the following ingredients: avobenzone, cinoxate, ecamsule, menthyl anthranilate, octyl methoxycinnamate, octyl salicylate, oxybenzone, sulisobenzone, titanium dioxide or zinc oxide. Use a sunscreen with a sun-protection factor (SPF) of at least 15. Apply sunscreen generously, and reapply every two hours — or more often if you're swimming or perspiring.
- Cover up. For protection from the sun, wear a broad-brimmed hat, which provides more protection than does a baseball cap or golf visor, and tightly woven clothing that covers your arms and legs. You might also consider wearing clothing designed to provide sun protection. An ultraviolet protection factor (UPF) of 40 to 50 provides the best protection. UV-blocking clothes can lose their protective feature if they are stretched, become wet or are washed repeatedly.
