The very height of summer, the abolition of quarantine, many thought about a vacation and began long walks around the city. It's time to talk about sunscreen! A few years ago, girls were striving to achieve a golden tan as soon as possible, and now cosmetologists unanimously shout: "Enough." We suggest you figure out what is SPF cream - a necessary measure or a marketing ploy?
Should you be afraid of the sun?

It turns out that even in cloudy weather, about 40% of UV radiation reaches the ground. Normally, part of the UV radiation is scattered in the ozone layer, but due to poor ecology, the earth's protective barriers are weakened. According to Roman Vilfand (meteorologist of the Hydrometeorological Center of Russia), the ultraviolet radiation index in southern Russia in summer can be compared with the radiation index in Africa. The lesser of the negative effects of UV rays on human skin is the premature appearance of wrinkles and pigmentation, the greater is the development of serious diseases, such as skin cancer.
Which SPF cream to take?

An SPF cream is a cosmetic product that displays an index that determines the level of sun protection. The number (from 10 to 100) next to the abbreviation tells how much UV light will get on the skin when using the product.
- Cream with SPF 10 index protects against 90% of rays,
- SPF 15 protects against 93% of rays,
- SPF 50+ neutralizes 98-99% of radiation.
In fact, the difference between the degree of protection is not very large, but it is it that affects the time that you can be in the sun. No cream can give one hundred percent protection, even if the tube says SPF 100 - 1% of ultraviolet radiation will still reach your skin. Therefore, one hundred percent protection can just be called a marketing ploy.
How to apply sunscreen?

Sanskrin should be applied in a fairly thick and even layer (2 mg per square centimeter of skin). If we give an everyday example, then for the face you need ¼ teaspoon of cream, and for the body ½ tablespoon. In terms of consistency, sunscreens are quite dense, so the time for getting ready for a walk will increase significantly. Without the cream completely drying, you will hardly be able to apply makeup. If you are planning to go to the beach, then make sure that your cream is also waterproof. Otherwise, after each contact with water, the protective layer will have to be renewed. For outdoor sports, there are special ranges of "Sport" branded sunscreens that will protect your skin even in times of high sweating.
How to store Sanskrin?

It may seem that the acquisition of Sanskrin is not a very profitable undertaking, but it is obviously useful and necessary. An important point concerns the storage of sunscreen. A closed jar can be stored for several years (the main thing is that it does not stand in the sun). But an open tube of cream will live only a year, and then it will lose all its useful properties. Increasingly, dermatologists are advising to apply Sanskrin not only in summer, but also in winter. The winter sun will not cause skin cancer, but it is quite capable of provoking photoaging. But this measure is aimed at saving beauty, not health. So, in this case, everyone makes a decision for himself.
