Your
Guide to SPF in sunscreens
When you are selecting
your SPF (Sun Protection Factor) level for sunscreen, do you
know exactly what the differet levels mean? If not, you are
not alone.
Here is the scoop
on how much of the sun's rays each level of SPF protects you
from.
SPF 4 blocks 75%
of the suns rays (allowing 25% through)
SPF 8 blocks 87.5%
of the suns rays (allowing 12.5% through)
SPF 15 blocks 93.3%
of the suns rays (allowing 6.7% through)
SPF 30 blocks 96.7%
of the suns rays (allowing 3.3% through)
SPF 50 blocks 98%
of the suns rays (allowing 2% through)
If you are fair
and tend to burn whenever you are in the sun, you want to
make sure you go with the highest SPF. If you are already
tanned, using a high SPF prevents you from getting darker
or use a lower SPF if you want to continue tanning.
It is important
to remember to reapply your sunscreen as the effectiveness
is reduced by the hour and when you do things such as go swimming
or even just sweating! More burns are caused by forgetting
to reapply!
