Sun Screen: Review 2015


  • Sun screens are either “physical blocks”, “chemical blocks”, or a combination.
  • Physical Blocks” are Zinc or Titanium.  (higher % is better)
  • Physical blocks tend to work better when swimming/ sweating etc. 
  • Only a small improvement in protection occurs by using higher SPF rating 
  • Most people only apply ¼ to ½ as much as is recommended.
  • The quantity and frequency is more important than the SPF rating  
  • All sunscreens are rated at less than SPF 10 if under applied.  
  • All sunscreens need to have a thick application  (This is impossible with aerosol spray types). 
  • When using “chemical” sun blocks avoid Oxybenzone(enters bloodstream and acts like estrogen), Retinyl Palmitate (increased skin tumors) and Spray Sunscreens (inhalation risk) 
  • “Chemical” sun screens can lose potency and should be replaced annually.
  • Remember:  Tanned skin is damaged skin 
  • Remember to apply all sun screens at least 15 minutes before exposure and to reapply approximately every 2 hours or after swimming. Remember to apply “lipblock” to the lips.
  • Infants should be covered from direct sun. If not possible then apply sun screens sparingly on exposed surfaces only.
  • Your best protection from the sun is shade, hats, long sleeves, sunglasses, swim tops, etc.
