SPF sunscreen and SPF sunscreen
Adults and children must protect themselves against the harmful actions of ultraviolet radiation on hot summer days. Whether you are on a beach or in the traffic of a big city, you should use sunscreen lotions or a sunscreen spray. Sunlight has been clinically shown to have the same effect wherever you are. Therefore, you must protect yourself at all times. Furthermore, people should use sunscreens and, above all, facial sunscreen, not only in summer, but also in winter. It is important to mention that many people confuse between sunscreen and sunscreen, thinking that the two terms can be used interchangeably. This is false; there is an important difference between the two sunscreen lotions. Zinc oxide sunscreen is a transparent lotion that has a reduced action against UVA and UVB radiation. Sunscreen is a more powerful tool against sunlight, it is a more opaque sunscreen lotion and acts as a barrier against ultraviolet radiation.
The first sunscreen lotion was invented in 1938 by Will Baltzer and became the basis for Piz Buin lotions. The first widely used sunscreens and sunscreens were invented in 1944. The concept of SPF (sun protection factor) was first used in 1962 and has since become the international unit of measurement for the effectiveness of sunscreens. sun protection.
Most sunscreen lotions, such as sunscreen sprays and facial sunscreens, contain oxybenzone, a derivative of benzophenone, which is an excellent chemical compound for absorbing medium-wavelength radiation. Although benzophenone has been shown to be highly effective in counteracting ultraviolet radiation, the compound can also attack DNA, and since 1993 its use in the manufacture of sunscreen lotions, facial sunscreens, and spray sunscreens has become questionable . Sunscreens and sunscreens also contain zinc oxide and titanium dioxide and other organic chemical compounds.
The average dose of sunscreen for the whole body is 29 grams, as approved by the FDA, for a person 5 feet 4 inches, weighing 150 pounds and about a quarter teaspoon of sunscreen for the face or sunscreen for the facial area. Sunscreen should be applied every 2 to 3 hours, while protective sunscreen lotions should be applied less often.
Failure to apply sunscreen lotions, facial sunscreen or sunscreen spray can lead, over time, to the development of squamous cell carcinoma (SCC), which is one of many forms of cancer and can occur at the level of skin, lips, mouth, lungs, prostate and other organs. In addition, basal cell carcinoma (BCC), the most widespread form of cancer, can be caused by not applying sunscreen and sunscreen.
