Skin Care MYTHS: The higher the SPF, the greater the protection.

Written by  

STATEMENT:

The higher the SPF, the greater the protection.

Facts:

The greatest protection is achieved by the correct use of a broad spectrum sunscreen that protects against UVA and UVB rays, wearing UVF clothing, a wide-brimmed hat, and sunglasses that block 99 to 100 percent of ultraviolet rays.
Sunscreen SPF ratings refer to UVB exposure only, the rays that burn you. A higher SPF provides only a slight increase in the level of UVB protection.

  • SPF 15 – provides 93 percent protection from UVB rays.
  • SPF 30 – provides 97 percent protection from UVB rays.
  • SPF 50 or higher – provides 98 percent protection from UVB rays.

Sunscreens that combine ingredients containing adequate SPF protection with zinc oxide, titanium dioxide, avobenzone, or ecamsule deliver broad spectrum protection. Most manufactures and dermatologists recommend 1.5 teaspoons of a broad spectrum sunscreen for the face and at least one ounce for the body; do not forget the bridge of the nose, the lips, and the tops of the ears. Clients should apply sunscreen 20 to 30 minutes before going outdoors and reapply every two hours and after swimming or perspiring.
