What does a sun protection factor mean?
Sun Protection factor is a way of measuring the amount of protection a sun block gives you.
Essentially a sun block with a sun protection factor of 20 give you 20 times protection from the sun. This means you’ll get similar injury to the skin from 20 minutes exposure with the sun block on to that you would get with one minute with the sunblock off.
We generally recommend that for adults they use a sunblock factor of at least 25 each day. This does not depend on if they live in a rainy wet country or sunny country, whether its winter or summer. For children this factor should go up to 40 and I would encourage you and your children to adapt daily sunblock application to their daily routine as soon as possible. Prevention is better than cure….
