According to different clinical studies, using a factor 15 photoprotector during the first 18 years of life can reduce the risk of skin cancer by up to 78%. Exposure to the sun is beneficial and necessary for human life; stimulates the synthesis of vitamin D, promotes blood circulation and promotes the treatment of some dermatoses.

The appearance of skin cancer is related, therefore, to exposure to sunlight for long periods of time and with intermittent and intense exposures. According to WHO estimates, more than two million skin cancers each year other than melanoma and 200,000 malignant melanomas occur worldwide each year.

More than 90% of skin cancers appear in areas exposed to the sun; The face, neck, ears, forearms and hands are the most frequent locations of a cancer whose main cause is invisible UV rays. The effects of these rays are increased by the wind and the reflective properties of the soil surface; the sand reflects between 10% and 25% of these rays, so the exposure of bathers is especially intense.

Other useful measures are the use of hats or wide hats, and sunglasses with approved glasses ".

"It is also advisable to use moisturizing lotions and painkillers after exposure, which act together, in order to calm the skin burning and alleviate and / or correct the anomalies caused by solar aggression. Finally, it is advisable to use clothes that protect the skin as much as possible, that does not let visible light go by ".

In addition, moisturizers are not enough to ensure adequate protection in summer, and hydration and nutrition play an important role; the experts emphasize in this sense that "to avoid heatstroke and the possible dehydration it is advisable to increase the consumption of water in the warm months; The recommended minimum daily is about two liters, an amount that should be increased by one or two more liters if you play sports or stay a long time outdoors.
