It seems that we are no longer afraid of the SPF inscription on the packaging of the cosmetic product. But, you see, it never became clearer for understanding.
Letidor decided to correct this unfortunate misunderstanding and asked Aleksandr Prokofiev, a dermatovenerologist, medical expert of the La Roche-Posay brand, to reveal the secrets about cosmetics with sunscreen factor.

In the first trimester of pregnancy, it is especially important to use cosmetics with SPF.
In the first trimester, all organs and systems in the embryo are laid, therefore any adverse effect from the outside or from the inside can have a negative impact on these processes.
Exposure to ultraviolet and infrared radiation from the sun can have a negative effect on the laying of not only the nervous system of the fetus, but other organs too.
The expectant mother should remember this and not get carried away with sunbathing during the period of solar activity, and she also needs to use sunscreens with a factor of 30 and above.

Cream with SPF-25-50 can prevent pigmentation
Chloasma is a pigmentation that occurs most commonly in women during pregnancy. Since the frequent localization of chloasma is open areas of the skin (face), this indicates the unfavorable role of ultraviolet radiation in its development.
The female sex hormones estrogens are photosensitizers, that is, they increase sensitivity to the sun.
Correct exposure to the sun, use of sunscreen with protection factors 25-50 significantly reduces the risk of developing chloasma.

For babies, you need to choose creams with the highest SPF index.
The skin of an infant is significantly different from the skin of an adult, it is extremely vulnerable to external factors, it contains very little of the protective pigment melanin.
Up to six months, the baby should not be exposed to direct sunlight at all.
Creams for babies (from six months) always contain maximum protection, and creams for children (from three years of age) may already have protection factors of 30-50.

The SPF value on the package does not indicate how long you can safely be in the sun.
The SPF index indicates how many times slower the development of erythema (redness) of the skin in the sun compared to exposure without using sunscreen.
Simply put, the "SPF 50" mark on the product's packaging says that skin treated with this cream will need 50 times more ultraviolet radiation to cause redness than the area where the cream has not been applied.
However, any sunscreen, regardless of the protection factor, must be renewed every 1.5-2 hours.
Hair sprays with SPF are able to protect curls from dehydration and preserve color pigment
Hair becomes porous under the influence of the sun, loses its shine and moisture. Using sunscreen sprays does more than just protect your hair from color loss. These products nourish and moisturize the hair structure.

SPF products should be used even when the weather is cloudy.
Ultraviolet light penetrates the clouds, affects us in the shade, and ultraviolet A is not retained even by glass. Therefore, sun protection is important at any time of the year, not only on the beach, but also in everyday life.
But keep in mind, there is no product that does not allow a single ultraviolet ray to pass through.
Even using sunscreen, you can get tanned. Modern sunscreens with a maximum filter block up to 98% of UVB and reduce UVA exposure by 45%.
For prominent areas of the skin, it is better to use cosmetics with SPF 50+
Areas such as the nose, forehead, ears, shoulders, chest, feet are more exposed to ultraviolet radiation. Therefore, they require more thorough protection.
In such areas, it is advisable to use additional special sticks with a high protection factor.

For the face, it is better to choose special products with SPF
The face, unlike the body, is exposed to ultraviolet radiation all year round, and therefore requires special attention. In addition, modern sunscreens for the face can help in solving some aesthetic problems (moisturizing, matting, masking). The choice of such funds, based on the needs of the skin, is quite reasonable.
Don't rely on SPF foundation as a substitute for sunscreen
Modern combined means that fulfill several aesthetic tasks, of course, make life easier in the modern frantic rhythm of the city. However, any tool has its main function, which it is designed to perform. In this case, it is toning.
Moreover, tonal means are used, as a rule, on the face, which means that some areas of the skin (ears, neck) remain unprotected.
Please note: most foundations use low filters of 10-20.
You also need to remember that sunscreens need to be renewed every 1.5-2 hours. Accordingly, this will also apply to the SPF foundation.

SPF products cannot be used after the expiration date
The formula of the product is stable and provides the degree of protection that is declared on the package for a certain time. After opening, the product begins to oxidize and gradually loses its properties.
The packaging usually shows the symbol "jar with an open lid" and a number on the jar - so many months you can use the product after the packaging has been opened.
In addition, it is important to store the products in a dry, dark place.
The windowsill or glove compartment of the car is not suitable for storage, and on the beach, cosmetics should be in a beach bag, and not on a towel in the sun.
