Technically, it is the ratio of how long you could spend in the sun before burning when you're protected by sunscreen, compared to when you don't have that protection. As of 2009, SPFs can range from 2 to as much as 100 or higher. A common mistake is applying too little sunscreen, which can drastically reduce the effectiveness of the product. About 1 ounce (a palmful) of sunscreen is recommended to cover the entire body, and it should be applied half an hour before sun exposure. You should reapply every two hours if you're staying outdoors for a long period of time. Applying sunscreen properly is one of the essential recommendations to lower your risk of developing skin cancer.

• Your level of sunburn risk x the SPF rating = safe sun exposure for your skin color
• The SPF number is a rating that determines how long you can stay in the sun without burning when you wear a sunscreen without needing to reapply it. It does not indicate quality of protection, just length of time.

• Level 1 skin (very fair) means you usually get a burn after 15 to 20 minutes of unprotected sun exposure. Determining your skin's response to various SPF ratings works like this:
  • SPF 15 x 20 minutes = 300 minutes (5 hours) of protection
  • SPF 30 x 20 minutes = 600 minutes (10 hours) of protection
  • SPF 45 x 20 minutes = 900 minutes (15 hours) of protection
• Level 2 skin (fair to light) ) means you usually get a burn after 30 minutes of unprotected sun exposure. Determining your skin's response to various SPF ratings works like this:
  • SPF 15 x 30 minutes = 450 minutes (7.5 hours) of protection
  • SPF 30 x 30 minutes = 900 minutes (15 hours) of protection
  • SPF 45 x 30 minutes = 1,350 minutes (22.5 hours) of protection
• Level 3 skin (light to medium/olive) means you usually get a burn after 40 minutes of unprotected sun exposure. Determining your skin's response to various SPF ratings works like this:
  • SPF 15 x 40 minutes = 600 minutes (10 hours) of protection
  • SPF 30 x 40 minutes = 1,200 minutes (20 hours) of protection
  • SPF 45 x 40 minutes = 1,800 minutes (30 hours) of protection
• Level 4 skin (medium to tan) means you usually get a burn after 60 minutes of unprotected sun exposure. Determining your skin's response to various SPF ratings works like this:
  • SPF 15 x 60 minutes = 900 minutes (15 hours) of protection
  • SPF 30 x 60 minutes = 1,800 minutes (30 hours) of protection
  • SPF 45 x 60 minutes = 2,700 minutes (45 hours) of protection
• Level 5 and Level 6 skin (brown to dark brown or black) means you usually get a burn after 120 minutes (2 hours) of unprotected sun exposure. Determining your skin's response to various SPF ratings works like this:
  • SPF 15 x 120 minutes = 1.800 minutes (30 hours) of protection
  • SPF 30 x 120 minutes = 3,600 minutes (60 hours) of protection
  • SPF 45 x 120 minutes = 5,400 minutes (90 hours) of protection

(Asian) and level 6 (Asian) skin should do just fine with a well-formulated sunscreen rated SPF 15. However, liberal application is still important. If you do not think you'll be applying the sunscreen as liberally as you should, consider a sunscreen rated SPF 30.
