Why is SPF the best anti-ageing ally?

The best anti-aging routine includes: a perfectly formulated cleanser, a serum rich in active ingredients and antioxidantsnot forgetting an exfoliating treatment to boost cell renewalan eye contour to erase signs of fatigue and, of course a nourishing moisturizer. But an anti-aging routine will never be at its most effective without sun protection. 80% of premature signs of skin ageing are caused by UV rays. And UV rays don't stop at the end of summer; they're constant all year round, penetrating the atmosphere even on cloudy days (and even through windows). In short, the sun's rays damage our skin every day of the year!

UVB rays are responsible for sunburn. They stop at the epidermis, but damage the cells' DNA. Although stronger in summer, they can damage and burn the skin all year round, particularly at high altitudes and on reflective surfaces such as snow or ice. 

 Finally, UVCs are the most dangerous, but they are absorbed by the ozone layer and by oxygen in the atmosphere, before reaching the earth's surface.

There are 4 SPF levels: 

• 6 to 10: representing low protection

• 15 to 25: representing medium protection

• 30 to 50: representing strong protection

• 50 and +: representing very high protection

Each sun protection factor corresponds to a percentage of UVB rays blocked. For example, SPF 20 blocks around 92% of UVB rays, while SPF 30 blocks around 95%. Finally, SPF 50 will block 98% of UVB rays. Even if the difference in the percentage of UV rays blocked isn't huge, protection will still be more effective and a high level of protection will be more appropriate, especially if you have fair skin. Do you have dark skin? Depending on your destination, you may opt for a medium to high protection factor. In all cases, however, suncare products can only deliver effective protection if certain golden rules of application are observed.
