What is the difference between factor SPF30 and SPF50?
What is the difference between factor SPF30 and SPF50? Contrary to popular belief, there is no big difference between sunscreens with an SPF above factor 15:
- SPF15: 93.3% protection
- SPF30: 96.6% protection
- SPF50: 98% protection
- 100% protection does not exist
How often should you apply? How often you should apply sunscreen is actually different for everyone. It has to do with your skin type, the sun strength at the time and what you do in the sun. Many Weather Apps give an indication of the current level of UV radiation.
The UV strength is always higher:
- closer to the equator
- higher in the mountains
- in spring and summer
- on clear days
Have you been swimming, sweating or drying yourself off? Then you need to re-apply. Even if it says 'waterproof' on the bottle. It is best to reapply every 2 hours.
Protect your ears and lips as well. For your lips, use special natural lip balms with SPF.
Do not apply too little. You will not be as well protected as it says on the packaging.
Tips:
- Get out of the sun at the hottest part of the day, between 12pm and 4pm, or find a shady spot
- You can also get sunburned in the shade, for example under a parasol. Not all sunshades are made of UV-resistant material. So apply a natural sunscreen even in the shade.
- Keep children under 1 year of age out of the sun altogether.
- Children see how you handle sun protection. So set a good example. Get out of the sun and rub in well. There are special natural sun protection products for children.
