Fifteen to 30 minutes before going outdoors, apply a broad-spectrum sunscreen that provides protection from both UVA and UVB light. Use a sunscreen with a sun protection factor (SPF) of at least 30. 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 tightly woven clothing that covers your arms and legs and a broad-brimmed hat, which provides more protection than does a baseball cap or golf visor.

Treatment isnвt necessary, but some people want to remove age spots because of their appearance. Your healthcare provider may prescribe bleaching creams to fade the age spots gradually.

If you want to use an over-the-counter cream, choose one that contains hydroquinone, deoxyarbutin, glycolic acid, alpha hydroxy acid, or kojic acid. Cosmetics donвt remove age spots. Instead, they cover them. Ask your dermatologist, plastic surgeon, or makeup counter salesperson to recommend brands that effectively conceal age spots.
