Sun Protection: Myths, Truths, and Expert Advice
Sun protection is often overlooked in our beauty routines, even though it's one of the most essential steps we take to maintain healthy, youthful skin. However, many misconceptions are circulating, causing confusion among consumers. In this article, based on scientific studies and the advice of dermatologists , we separate the facts from the fiction and guide you in choosing the sun protection best suited to your skin and needs.
☀️ Why use sunscreen?
An essential barrier against UV rays
Ultraviolet rays (UVA and UVB) are responsible for 90% of the visible signs of skin aging ( Skin Cancer Foundation ). They penetrate the skin and cause:
- premature wrinkles
- pigment spots
- loss of elasticity
- skin cancers
According to a study published by the Regional Health Agency (2024), daily use of sunscreen reduces the risk of melanoma by 50% .
Sun protection isn't just for summer
It's a common myth: the sun doesn't only shine in the summer. UV rays are present all year round , even on cloudy days or in winter. They also penetrate windows, which is why daily use is important.
🕒 When should you use sunscreen?
Every morning, even indoors
Applying sunscreen every morning should be part of every beauty routine. Even indoors, UVA rays can penetrate through windows and affect the skin.
To be renewed every two hours
The effectiveness of sunscreens decreases over time. It is recommended by dermatologists ( DERMATO-INFO ) to reapply every two hours , especially outdoors or after swimming/sweating.
🤔 Which sunscreen should you choose?
Understanding SPF
The SPF ( Sun Protection Factor ) indicates the level of protection against UVB rays, which cause sunburn. Here are the main points:
- SPF 15: blocks 93% of UVB rays
- SPF 30: blocks 97%
- SPF 50: blocks 98%
👉 For daily use, a minimum SPF 30 is recommended.
Mineral vs. Chemical Filters
- Mineral filters (zinc oxide, titanium dioxide): reflect UV rays, ideal for sensitive skin.
- Chemical filters (avobenzone, octinoxate, etc.): absorb UV rays, making them more invisible on the skin.

| Skin type | Recommendation |
|---|---|
| Oily skin | Gel formulas, Oil free |
