Obagi Sun Shield Matte Broad Spectrum SPF 50

Obagi

Ultraviolet, Visible and Infrared Rays Penetrate Through Multiple Layers of Skin

UVB REACH OF RADIATION

  • Wavelengths span 280 nm to 315 nm
  • Inflicts more potential damage in superficial epidermal layers but may penetrate to the dermis

UVB HARMFUL EFFECTS

  • A primary cause of skin reddening and sunburn
  • A factor in the development of skin cancer
  • Contributes to hyperpigmentation and other signs of photoaging

UVA REACH OF RADIATION

  • Wavelengths reach between 315 nm and 400 nm
  • Rays are consistently intense throughout daylight hours, regardless of season or cloud cover
  • Radiation penetrates dermis, deeper than UVB
  • Delivers about 95% of the UV radiation reaching the Earth’s surface

UVA HARMFUL EFFECTS

  • Accelerates photoaging effects
    —Wrinkles
    —Roughness
    —Blotchiness
    —Hyperpigmentation
    —Poor skin tone
    —Sallowness
  • Damages keratinocytes, thereby contributing to the development of skin cancer

IR REACH OF RADIATION

  • Near IR wavelengths are between 780 nm and 1400 nm
  • Manifested as heat on the skin’s surface
  • Penetrates deeper than UVA and UVB rays, reaching the subcutaneous layer of skin
  • Accounts for about half of all solar energy reaching the skin

IR HARMFUL EFFECTS

  • Associated with loss of skin elasticity
  • Induces production of free radicals
  • Combined with UV rays, shown to inflict cumulative damage

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 provide:

  • 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 sunscreen>
  • Water resistance

Different Ingredients Provide a Range of Benefits

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