Sunscreen

Sun protection is the chapter of cosmetics where science is clearest: protecting yourself well means preventing sunburn, photoaging, and skin damage. In this section, you will find the complete solar universe: face and body protections in every SPF and texture, after-sun products, self-tanners, and sunscreens specifically for children and sensitive skin.

How to choose the right sunscreen

The first criterion is the appropriate SPF for your skin type and exposure: fair skin and intense exposure require SPF 50+, and in any case, starting high in the first days is the correct strategy. The second is the spectrum: look for UVA protection (the UVA circle on the label) in addition to UVB — these are the rays responsible for photoaging, which are present even on cloudy days. The third is the texture that you will actually use: lotion, spray, gel, or cream — the best protection is the one that you are happy to reapply.

The rule that no product can bypass: generous amounts and reapplication every two hours and after every swim. Most sunburns "with protection" occur due to halved doses.

Frequently Asked Questions

What does SPF 50 mean compared to SPF 30?

SPF 50 filters about 98% of UVB, while SPF 30 filters about 97%: the real difference lies mainly in the margin of error allowed for imperfect application.

Is last year's sunscreen still good?

Check the PAO symbol (months since opening, typically 12): beyond that window, or if the product has changed smell and consistency, the protection is no longer guaranteed.
