Every summer, using sunscreen becomes second nature. However, its actual effectiveness depends as much on the product you choose as on how you use it. Here’s a breakdown to help you adopt the right habits and better understand sun protection.
SPF, UVA, UVB: What You Really Need to Know
The SPF (Sun Protection Factor) is well known today. But it reflects only part of the protection:
- The SPF measures only protection against UVB, which causes sunburn (ISO 24444 standard)
- the UVA, on the other hand, penetrate deeper into the skin and contribute to photoaging and skin cancer
In Europe, regulations require a minimum level of UVA protection: it must account for at least one-third of the stated SPF (Recommendation 2006/647/EC)
A simple indicator: the presence of the UVA logo surrounded by a circle, which guarantees this balance.
Protection that is often overestimated
Contrary to popular belief:
👉 No sunscreen blocks 100% of UV rays
In addition, the conditions of use in the laboratory (2 mg/cm²) are rarely met in practice.
The result: actual protection is often less than what is stated on the packaging
That is why health authorities (Santé Publique France, the European Commission) emphasize:
- the amount applied
- the frequency of reapplication (every 2 hours, and after swimming)
combining it with other measures (hat, clothing, shade)
Choosing the right sunscreen for your lifestyle
The “right” solar system isn’t one-size-fits-all. It needs to be tailored to your daily life:
Intense sun exposure (beach, mountains, sports): Choose a very high SPF (SPF 50+) that is water-resistant
For daily use: lightweight, invisible, easy-to-apply formulas
Sensitive areas (face, lips, scars): targeted formulas, easy to reapply
👉 Formulation plays a key role: the more pleasant a product is to use, the more likely it is to be applied correctly and regularly.
A small act of kindness makes all the difference
Effective sun protection is based on three pillars:
✔ Choose the right product
✔ Apply a sufficient amount
✔ Renew regularly
It is this combination that truly reduces the risks associated with UV exposure, both in the short and long term, and thus provides effective protection.
