The sun feels wonderful, but your skin needs protection. Yet sun protection remains a mystery for many people. What does that SPF value actually mean? Is a higher factor always better? And what is the difference between chemical and mineral filters? In this article, we walk you through everything you need to know to choose the right sunscreen - and how to save smartly in the process.
What does SPF mean?
SPF stands for Sun Protection Factor. The number indicates how much longer you can stay in the sun before your skin turns red, compared to no protection at all. An SPF 30 theoretically means you are protected 30 times longer.
But here is the catch: that is theory. In practice, protection depends on how much cream you apply, how often you reapply and whether you sweat or swim. Most dermatologists recommend at least SPF 30 for daily use and SPF 50 for extended outdoor exposure.
The SPF myth: SPF 100 is not twice as good as SPF 50
A common misconception: SPF 50 blocks about 98% of UVB rays, while SPF 100 blocks about 99%. The difference is minimal, but the price difference can be significant. For most people, SPF 50 is more than sufficient.
Chemical versus mineral sun protection
There are two main types of sun filters, and the difference is bigger than you might think.
Chemical filters
Chemical sunscreens are absorbed by the skin and convert UV rays into heat. They contain ingredients like oxybenzone, avobenzone and octocrylene. The advantage? They spread easily and leave no white cast.
The downside is that some people are sensitive to them. People with reactive skin, rosacea or eczema may experience irritation. Additionally, the environmental impact of certain chemical filters is debated - oxybenzone is already banned in some countries due to its impact on coral reefs.
Mineral filters
Mineral sun protection, with zinc oxide or titanium dioxide, acts as a physical shield on your skin. Rays are reflected rather than absorbed. This type is particularly suitable for sensitive skin, children and people allergic to chemical filters.
The traditional downside - that notorious white cast - is much less noticeable nowadays thanks to micronized formulas. Brands like Vichy have significantly improved their mineral formulations.
How to choose the right sun protection?
The ideal sunscreen depends on your skin type, activities and personal preferences.
Skin type: Sensitive skin? Go mineral. Normal to oily skin? Chemical or hybrid formulas work well.
Activity: Swimming or exercising? Choose a water-resistant formula. For daily use under makeup, a light texture is ideal.
