Most kids suncream is available with SPFs 15, 30 and 50; but what is the difference between them? In summary, the difference is the percentage of protection you’re getting:
- SPF15 - blocks around 93% of UVB rays
- SPF30 - blocks around 97% of UVB rays
- SPF50 - block round 98% of UVB rays
Should I use factor 50 or factor 30 on my child?
There is no reason to choose a lower SPF for a kids suncream - it’s always best to select the highest SPF you can so that your child has the highest level of protection from the sun. With this in mind, it's best to go for SPF50 wherever possible.
It is important to understand that just because the SPF is higher, doesn’t mean it lasts any longer than a sunscreen with a lower SPF. You will still need to reapply the suncream for kids just as frequently to ensure that they’re getting the best level of protection from the sun.
