know the SPF you need

*summer is back,and stepping out without putting on a sunscreen means you are likely to do a lot of damage to your skin,every sunscreen contains spf(sun protection factor),a number that let's you know how long you can stay out in the sun without burning your skin,for instance,if your skin starts turning red after 10 minutes in the sun,an spf of 15 allows you to stay out for 150 minutes wihout burning.
]*skin experts recommend that everyone should use atleast spf 15 before they step out in sun,if you are going to spend a lot of time out in the sun,use spf 30 or higher.,whichever spf value that you use,be sure to reapply the sunscreen every two hours,else its effect wear off,even if the suncreen is waterproff,you need to apply it every two hours as it comes off because of water and sweat.
*mixing products with spf does not necessarily add upto higher protection,for instance,using an spf 15 moisturiser with an spf 15 sunscreen does not result in spf 30 protection.
*spf has its limitation though,it only measures the protection yo get from uvb,which are the sun ray's that cause burning,an spf does not tell you how much protection,if any,you are getting from the sun's uva rays which are responsible for tanning,and premature aging of the skin,to ensure you are protected against uva as well uvb,make sure that your sunscreen contains avobenzone,titanium dioxide,or zinc oxide.
*tips for sunscreen use:
a.don't skip areas including ears and lips,all exposed parts of your body needs sunscreen.
b.while sunburns are immediate signs,without regular sunscren use,you could eventually see wrinkles,skin discolouration,and skin cancer.sun damage acumulates over the years.
c.to ensure that you get the amount of spf on the product label,you need to apply it generously and evenly all over your skin.put on sunscreen at leat 20 minutes before you go outside ,because the chemicals need time to bond with your skin before they are totally effective.
