    Daily Sun Protection Is Essential to Help Preserve Skin HealthThe Importance of Sunscreen Composition

    The American Academy of Dermatology recommends daily use of sunscreens that provide8:

    • Broad-spectrum protection against UVA and UVB radiation
    • Sun Protection Factor (SPF) of 30 or greater
      —SPF indicates the duration of protection against UVB rays vs not using a sunscreen3
    • Water resistance

    Different Ingredients Provide a Range of Benefits

    • Minerals such as zinc oxide or titanium dioxide deflect solar radiation9
    • Chemicals such as octyl methoxycinnamate or oxybenzone absorb UV radiation and disperse it as heat9
    • Newer technologies address infrared radiation by helping to buffer the skin from the heat-derived oxidation process4,10
