Can you stay in the sun for longer if you use a higher SPF sunscreen?
Yes, but in reality the extra protection is likely to be less than the higher SPF number suggests.
Summer has officially arrived. So we all need to be paying even more attention to how we can protect ourselves from the sun's damaging rays, and this includes making sure we choose the right sunscreen.
While sunscreens that are SPF50+ have been on our shelves for about two years, many of us are still confused about just how much protection they are going to offer, especially when compared to SPF30+ (or just SPF30 as may be seen on newer labels).
It's easy to assume you could safely stay in the sun almost twice as long when you choose SPF50+ over SPF30, after all 50 is nearly double 30. But is this really the case?
