FDA (US Food & Drug Administration) set out some rules last year regarding the sunscreen labelling. Quick guidelines:
– Labels not carrying “broad spectrum do not guarantee protection from skin cancer/premature ageing as most of the sunscreens claim to do these days.
– Higher SPF does not mean better protection, in other words the more SPF you can afford means more safety to you. Not all SPFs are the same and merely buying higher SPF will not do you good if you don’t consult a doctor first.
– The basic rule applies that SPF higher than 50 are as good as SPF 50, so brands may only write SPF 50+ on their labels.
– Buy products with a minimum SPF 15 and you will be assured safe from the sun.
