What does sunblock function?

  • SPF in sunblock  means Sun Protection Factor. Literally it means how much of time you can stand under the sun without getting sunburned.
  • For example, SPF 30 would allow you to stand under the sun in 30 times longer the period you can without any sun protection.
  • Generally, sun damage on our skin is happening since we are born. UVA and UVB can cause accumulative sun damage to our skin.
  • Sun ray can be reflected from any reflecting surface such as water, mirror, glass, and etc. So sun damage on our skin is happening all the time whenever there is sun appearance.
