    I try to be religious about applying sunscreen all year around.not sure whether am meant to reapply during day though. Say this morning I applied factor 30 to face before walking into work. Worked in office until lunchtime then went out again for 30 minutes-should I have applied again? is it the total number of hours outdoors I should consider or does it 'wear off ' even when indoors.

    I heard a skin specialist on the radio last year say that the factor in sunscreen represents how many minutes it will last x 10. So a factor 30 would last 300minutes (5 hours). She said that once you go over factor 30 that you cant guarantee it will last any longer than five hours.

    Hope that helps

    Be very careful about what type of sunscreen you use. Many main brand sunscreens can contain very toxic products linked with the acceleration of certain cancers including skin cancer. They also block absorption of Vit D which is needed to prevent many common cancers. Try googling 'sunscreen' 'dangers of sunscreen' or if you are chemically knowledgeable have a look at your sunscreen ingredients on the bottle, Oxybenzone,Octyl methoxycinnamate,Retinyl Palmitate (known to cause or accelerate skin cancer) are particularly nasty. I cringe when i see mothers apply to babies. Sunscreen is not regulated by the FDA so cosmetics companies can use what ever products they want. I would suggest a hat is a cheaper and safer alternative.
