Exposure to ultraviolet light, UVA or UVB, from sunlight accounts for 90% of the symptoms of premature skin aging including wrinkles The most important skin-care product available to prevent wrinkles is sunscreen, but most people do not use sunscreen correctly.

Composition of Sunscreens— What is the Best SPF? 26th June 2010
It used to be said that you only needed an SPF 15. Fine as far as it goes as SPF 15 really only protects against UVB—the rays that cause a sunburn. The UVA rays cause the cancer, tan, and wrinkles and they are not be protected by the lower number sunscreen. Recent research shows that the higher number sunscreens SPF 60 that contain Mexoryl SX, titanium dioxide, and Parsol 1789 are the most effective. A new development in sunscreens is to micronize them—but there is some loss of UVA protection with this physical change in the sunscreen properties. The best sunscreen is the one you have on! They are no good to any of us if left in the bottle. Be sure you carry a small bottle in your pocket or purse so you can reapply every 1-2 hours—particularly if outside with strenuous activities which makes us sweat the screen off.
