Maybe you're applying sunscreen incorrectly and you don't know it.

Barcelona"Although dermatologists are understanding, it's important to be clear: a healthy tan doesn't exist," says Alejandro Fernández, from Sanitas' CIMA Hospital. A tan is actually evidence of the damage radiation causes to the skin.

To prevent this, sunscreen is a good remedy. "During peak radiation hours—between 11 a.m. and 5 p.m.—sun exposure is generally not recommended. But if there's no other option, it's necessary to do so with a good sunscreen." Now, how can we know if we're using it properly?

Protection according to skin type and time of day

For people with fair skin, it's advisable to use sunscreen regularly, especially on areas such as the face, décolletage, hands, and forearms, which are constantly exposed. "Having a darker face than your feet doesn't mean you need less protection; quite the opposite. Chronic exposure means you'll accumulate more solar radiation throughout your life and pose a higher risk of skin cancer."

Creams before and after bathing

The specialist recommends applying the cream both before and after bathing. "In the water, we are exposed to even more radiation, due to the mirror effect of liquids." In these cases, he recommends using sunscreen.waterproof, which adhere better to the skin and dissolve less with water. Also remember the general rule: reapply sunscreen every two hours or after each swim.

Regarding the SPF, Fernández clarifies that "the difference between a 30- and 50-sunscreen is minimal: a 30-sunscreen already filters out 95% of the radiation. The important thing, in the end, is to reapply."

For children, those with dry skin, or people who will spend a lot of time in the water, Fernández recommends creams rather than sprays, as they are more hydrating.
