Daily Sun Protection Is Essential to Help Preserve Skin Health

The 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
