10 rules for the use and purchase of sunscreen
UVA radiation-rays penetrate deeper into the skin. They can cause destruction of DNA structure. The result is premature skin aging.
UVB radiation-causes dandruff and peeling of the skin, burns and melanoma and even skin cancer.
There are rules to help you choose a sunscreen. The choice depends on the phototype of the skin (skin color), sensitivity to sun exposure, skin type (oily, dry, normal, combination), and skin condition (healthy or with some disease). It is important to consider the latitude and longitude of the destination, because UV radiation and sun protection factor depend on it. The purpose of applying sunscreen is to prevent or reduce the harmful effects of UV (ultraviolet) radiation. This is achieved with UV filters or physical blockers. UV absorbers selectively absorb UV radiation that they emit in the form of long-lasting and less harmful. Physical blockers protect the skin because they reflect and scatter rays that reach the surface of the skin. The sunscreen should therefore have a UVA sign in the circle in addition to the marked SPF (which refers to UVB protection). Then the person can be sure that he also has adequate UVA protection and provides a wide range of protection. Otherwise, burns will not occur, but the skin will not be protected from the effects of UVA rays, the consequences of which are long-term and cannot be seen immediately, although they can be more dangerous and serious.
Cosmetologists say that 200 ml of the preparation is enough for only 5 lubrications of the whole body (skin surface). Sunscreen should be applied half an hour before sun exposure and after sun exposure. The layer should then be renewed every hour and after each stay in the water.
