Why does Maintenance 1 contain SPF 20?
Exposure to sunlight is known to be the leading cause of premature skin aging. Unlike many sunscreen products currently available, Maintenance 1 contains one of the most advanced sunscreens on the market–providing broad-spectrum protection against both UVA and UVB damage. If you are involved in outdoor activities with increased sun exposure, or desire even more protection, you can apply a sunscreen with even higher SPF over Maintenance 1.
