Solar radiation can cause skin damage if care is not taken regarding the dose received. Daily use of sunscreen, for example, can prevent diseases caused by overexposure to the sun, such as small lesions, calluses and other blemishes, as well as skin cancer – which is most common in Brazil, with about 30% of all malignancies recorded from By the National Cancer Institute (INCA). Expert guidelines suggest that the sooner a person uses it, the less damage will be done over the years.
According to Faculdade Anhanguera’s Pharmacy Course Professor, Professor Inara Amoroso da Silva Luccas, creating a skin barrier through the use of sunscreen will contribute to health and beauty. “With this habit, it is possible to postpone the signs of aging caused by ultraviolet (UV) radiation, which stimulate the deterioration of collagen fibers and make the skin of the face lose its strength and support,” he says.
Sun exposure risks occur at all times of the year, including cloudy and rainy weather, however, there is an increased incidence of problems during the summer, when the days are longer and the heat is more intense. During this period, it is also advised to wear light clothing, with good coverage, and hats, as well as to avoid the sun between 10 am and 4 pm.
The composition of sunscreens has different formulations and compositions, classified into organic and inorganic filters. Organic substances consist of molecules that are able to absorb ultraviolet radiation (high energy) and convert it into electromagnetic waves of low energies that are harmless to humans. The inorganic option is represented by oxides of zinc and titanium. These sunscreens are the safest and most effective form of protection, they have a low potential for irritation, and they are also recommended as light sunscreens for use by children and people with sensitive skin.
Lotions work by partially or completely blocking the action of ultraviolet rays, and the sun protection factor (SPF), indicated on the package, displays the potential of the protective barrier created in the skin for a period – for example, if the sun protection factor is 10, it means that A person can be exposed to the sun for 10 times longer than the same amount of time without protection.
“Therefore, it is advisable to read the leaflet to check which one is most suitable for each type of skin and to clarify doubts with a pharmacy specialist to discover the best product for each patient,” says Prof.
