SPF.

You should wear sunscreen on skin not covered by clothing everyday you go outside. This is because the sun emits harmful UV rays everyday, rain or shine (up to 80% of harmful UV rays penetrate through clouds!).

Sun protection factor (SPF) is a measure of how much solar energy is required to sunburn protected versus unprotected skin. A higher SPF value indicates a higher protection rating.

When choosing a sunscreen, it is recommended to choose one that offers the following:

  • SPF 30 or higher
  • Broad spectrum protection
  • Water resistance

Not protecting your skin from the UV rays can worsen skin conditions and even lead to developing skin cancer.
