At Nomige we often get the question whether a higher SPF is really that much better at protecting your skin. A higher protection factor tends to reassure people on the efficiency in protecting your skin from harmful UV-rays.However, research shows that the difference between SPF30 and SPF50 is much lower than you might think.
What is SPF and how does it protect your skin?
Let’s start with the meaning of SPF:
SPF means “Sun Protection Factor”
The SPF number tells you how long the sun’s UV radiation would take to redden your skin. Ideally, with SPF 30 it would take you 30 times longer to burn than if you weren’t wearing sunscreen. In essence SPF efficiency is a measure of the percentage of harmful UV-rays it block from being absorbed by your skin.
In the image below you can see how sunfilters protect our skin:
The image shows photons from the sun reacting with our skin in 3 different situations ( no sunscreen, SPF15, SPF30).The photons are little particles which constitute the sun rays and the sunfilter works like a barrier to avoid them to enter into the skin.
The table below shows the different SPF factors with their corresponding % UV-rays they can effectively block (when applied correctly):
In order to visualise the way different sun protecting factors protect your skin and how they differ from each other, Dr Barbara Geusens conducted a short experiment in her new skintip video.

Not convinced you have to wear sunscreen everyday? Maybe these facts can change your mind:
A single blistering sunburn can nearly double one’s lifetime risk of melanoma, the most deadly form of skin cancer.
Unlike UVB rays, UVA rays are not absorbed by the ozone layer and they are not filtered by windows or clouds. This means you are ALWAYS exposed to harmful UV rays.
