Why is it the number 1 anti-aging product? To take full advantage of the sun while protecting your skin (and your youthful capital) from the harmful effects of ultraviolet rays, it is essential to use suitable sunscreen products and not to underestimate the importance of sun protection. Face and body sunscreens are your best allies to protect your skin, but you still need to understand how they work and how to use them.
These sunscreens, whether in spray, stick, mist, lotion, sun oil, tinted, containing mineral filters, for the face or body, against UVA or UVB, including organic sunscreen, prevent premature skin aging and the risk of skin cancer, while maintaining optimal hydration for sensitive skin. After-sun care, such as milks and balms, soothe and repair the epidermis after sun exposure, thus ensuring complete protection adapted to all needs.
In this article, we demystify UV protection indices, sunscreens, best practices for a safe summer and some fun facts to shine in society!
Everything you need to know about SPF!
SPF, or Sun Protection Factor, is available in a wide variety of forms on the market, but it's hard to choose the right combination when you don't know what it really means! Hang on, the fun facts in this article will help you become an expert.
First the basics: What is SPF?
SPF indicates the level of protection a sunscreen offers against UVB rays. These are the ones responsible for your sunburn and some skin cancers. The higher the number, the greater the protection. For example, a sunscreen with SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%.
#1 FUN FACT:
SPF comes to us from Austria! Developed in 1938 by chemist Franz Greiter after suffering from sunburn while hiking.
#2 FUN FACT:
The first SPF tests were done on... milk!: Before being tested on human skin, some of the first sunscreens were tested on tubes of milk. Researchers measured how long it took for the milk to start degrading under UV light compared to an unprotected sample.
#3 FUN FACT:
SPF 100 = double protection VS SPF 50 ? This is FALSE! A SPF of 50 blocks about 98% of UVB, while a SPF of 100 blocks about 99%. The difference is minimal, which means that correct and regular application is much more important than the number indicated.
Myth or Fact: Is SPF Waterproof?
No sunscreen is completely waterproof. The terms “water-resistant” or “highly water-resistant” only indicate that the cream maintains its SPF after 40 or 80 minutes of swimming or heavy sweating. So it’s crucial to reapply your sunscreen regularly to ensure continued protection.
The million dollar question: Chemical filters or physical filters?
There is no wrong choice, the worst choice would be not to make one!

Less irritating: Better suited for sensitive skin and children. |
So, how do you choose the right SPF?
The choice of SPF depends on 3 factors:
- Your skin type : Light skin tones generally require higher protection (SPF 30 or higher), while darker skin tones can get by with SPF 15 to 30.
- The intensity of sun exposure : For a day at the beach or in the mountains, opt for a higher SPF. For a quick outing in the city, an SPF 15 may be enough.
- Duration of exposure : The longer you plan to stay in the sun, the higher the SPF you should choose.
How to apply sunscreen correctly?
For optimal protection, here are some of my tips:
- Apply generously : Don't hesitate to use enough cream. A common mistake is not putting enough, which reduces the effectiveness.
- Don't forget the often overlooked areas : The ears, neck, feet and backs of the hands are often forgotten, so be sure to cover them as well.
- Reapply regularly : Remember to regularly apply a layer of sunscreen to maintain good protection throughout your sun exposure. Every 2 hours and after swimming or heavy sweating.
And after the exhibition, what are the right actions?
- After-sun is essential to soothe and moisturize the skin after exposure to the sun's rays. Cosmetic products such as lotions, sun milks, and after-sun balms, enriched with aloe vera, vitamin E, monoi or shea butter, are perfect for maintaining hydration and repairing the epidermis. Using after-sun care helps prevent premature skin aging caused by UVA and UVB rays, as well as free radicals. These protective and antioxidant-rich products are essential to prolong the tan and protect the skin from the harmful effects of the sun, while maintaining a feeling of freshness and comfort.
Conclusion
Sunscreen is a crucial tool, but it shouldn’t be your only method of UV protection. By incorporating appropriate clothing, seeking shade, and avoiding peak travel times, you can greatly reduce your risk of skin damage. Combine these strategies for complete sun protection and enjoy the sun safely!
With these tips, you are ready for a carefree summer, armed with knowledge to effectively protect yourself from the sun's harmful rays. Happy holidays and stay protected!
