Sun protection

Sun protection plays a key role in preserving your skin’s health and appearance by blocking harmful UV rays. These rays cause photoageing, induce pigmented spots and increase the risk of skin cancer. Adopting suitable protection shields your skin from external stressors while preserving its radiance and elasticity.

How to apply sunscreen?

Premature ageing, skin cancer, burns... The sun can prove dangerous for the skin, regardless of the weather and whether you are indoors or outdoors. That's why it's necessary to block all UV rays. Therefore, the daily use of a sunscreen is essential. Even though the importance of applying sunscreen every day seems to be understood by most people, questions still remain, particularly about its application: how to apply it correctly?

Why is it necessary to apply sunscreen every day?

Wearing sunscreen is one of the simplest steps to preserve skin health and appearance, regardless of age or phototype. Yet its use often remains occasional, limited to summer or prolonged sun exposure. Dermatologists and public health authorities agree that daily sun protection is essential, even in winter, on cloudy days, or indoors. Why this consensus? This article explains why daily sunscreen matters.

FAQ about sun protection

How long before sun exposure should you apply sunscreen?

It is recommended to apply sunscreen 30 minutes before sun exposure based on testing methods. Protocols require a 15 to 20 minute drying period before measuring the sun protection factor to ensure water resistance. No evidence indicates sunscreen efficacy is delayed.

How many times should you reapply sunscreen during the day?

It depends on the activity. For prolonged exposure at the pool or beach, we recommend reapplying the sunscreen every two hours. In contrast, for a commute between home and the office, a single application in the morning is sufficient.

Does SPF protect against UVA?

The SPF measures the filtration rate of erythemal UV rays by a sunscreen, which comprise 85% UVB and 15% UVA.

After several days of sun exposure, is it possible to reduce the applied SPF?

According to some studies, applying sunscreen for several consecutive days before UV exposure may establish a baseline protection in the skin. This might suggest that switching to SPF 30 is possible after using SPF 50 for several days. However, research remains limited, and as a precaution, a high SPF is recommended throughout the exposure period.

Are tinted products with SPF sufficient to protect skin?

Makeup products with SPF offer supplementary protection but are insufficient on their own for complete, lasting sun protection because they are not applied in sufficient quantities.

Should you apply sun protection in winter?

Yes, it is recommended to apply a sunscreen throughout the year. Even in winter, lower UV levels can accelerate photodamage and worsen photosensitive conditions such as hyperpigmentation or acne.

Are waterproof sunscreens water-resistant?

Waterproof sunscreens offer limited water resistance. They cover swimming and must be reapplied after swimming.

Does layering multiple sunscreens increase sun protection?

No, SPFs cannot be added together. However, pairing skincare with a sunscreen helps ensure that enough sunscreen is applied to reach the labelled protection factor.

Is sun protection necessary under a parasol?

Yes, a sunscreen is necessary under a parasol because UV rays reflect off sand and water.

What are the risks of using expired sunscreen?

An expired sunscreen has lost its ability to reflect and absorb UV and does not protect against the sun. It may cause skin reactions.
