SPF And Suncreen
April 20th, 2007
- SPF (Sun Protection Factor) indicates the strength of a sunscreen to block out the sun’s UV rays. It ranges from SPF 2 to SPF 60. If a person under the sun gets a burn after 20 minutes, then with a sunscreen of SPF 30 it would need 30 times of the 20 minutes to get a burn. A higher number means longer protection.
- Sunscreen, also known as suncream or sunblock, must be applied 15 to 30 minutes before stepping outdoors. Give it time to get absorbed into the skin. Apply generously, re-apply often especially after heavy sweating or swimming.
- A sunscreen that offers broad spectrum protection protects the skin from a wider range of harmful rays.
- Water-resistant suncreens could lose their effectiveness after about 80 minutes in the water.
- Do not use sunscreen on babies under 6 months old.
- Sunscreen does not guarantee one will not be at risk of skin cancer.
