Why you need powerful sun protection.

Creams with SPF 50 are considered by many to be overprotective, preventing them from getting the long-awaited tan, and they refuse to use them. And completely in vain. From photoaging, thinning, hyperpigmentation, and even what is worse (for example, melanoma), the skin is most effectively protected by the “fifty”. We will find out how such funds work, what advantages they have and who needs them in the first place.

What does the SPF 50 mark on the cream bottle mean?.

The abbreviation SPF stands for Sun Protection Factor, that is, “sun protection factor”. And the number 50 is the protection level, which shows how effectively SPF protects the skin from UVB sun rays. Without protection, the skin of an adult can burn in 15–20 minutes of exposure to the sun, the skin of a child – three times faster.

Protection is weakened due to the fact that we usually apply 2-3 times less cream than recommended.

There are three types of solar radiation.

UVA rays are 320-400 nm long and penetrate clouds, glass and epidermis. These rays reach the cells of the dermis and, although their effect is painless, they cause enormous damage: they provoke the appearance of wrinkles, age spots, photodermatitis, and oncological diseases of the skin.

UVB rays have a length of 290-320 nm, some of them trap clouds and glass, they do not penetrate deep into the skin – they stay at the level of the epidermis. That is why this type of radiation is responsible for the appearance of sunburn. And it also causes sunburn. By the way, tanning is nothing more than a protective reaction of the skin to damage.

UVC rays are the most dangerous, they are blocked by the ozone layer of the atmosphere (this is why ozone holes are so dangerous).

Remember that SPF only protects against UVB radiation, so the sunscreen packaging must be specifically labeled for UVA protection..

The UVA protection option is indicated by a special marking:

Asian funds – PA +++;

American – the phrase “broad spectrum”;

European – circle UVA icon.

Differences SPF 50 from lower values.

According to the American Skin Cancer Association, SPF 50 protects against 98% of rays. For comparison: products with SPF 30 can save from 97%, with SPF 15 – from 93%. It may seem that the difference is not critical, but for people with photosensitivity (allergy to the sun) or those who are predisposed to cancer (oncology in the past or in close relatives), it is very noticeable.

What type of skin is recommended.

First of all, creams with a SPF 50 protection factor are necessary for children, as well as for representatives of phototypes 1, 2, 3.

The first phototype (based on the table developed by the American scientist Thomas Fitzpatrick) includes people with milky-white freckled skin, light or red hair, and light eyes.

The second – people with fair skin, blond hair and light or brown hair.

To the third – people with dark skin, dark blond or light brown hair, brown or light eyes.

Representatives of the remaining three phototypes (dark-skinned and dark-skinned people with black hair and dark eyes) SPF 50 will come in handy on vacation in hot countries.

Which sunscreen with SPF 50 is better to choose.

There are several factors to consider when choosing a sunscreen:

weather conditions: in cloudy weather, the protection factor may be lower (you remember that UVB rays, from which the SPF protects, are partially blocked by clouds);

individual characteristics of your skin: type, tendency to allergic reactions, heredity;

Sun filter type.

This is another parameter that must be taken into account when choosing a sunscreen..

Physical (inorganic, mineral) filters.

These include zinc oxide and titanium dioxide, which reflect the sun’s rays like a mirror..

Chemical (organic) filters.

There are many filters of this type, among them – avobenzone, oxybenzone, octinoxate, etc., they absorb sunlight.

good tolerance, long-term action, photostability.

UVA protection, good cosmetic properties, targeted action, the possibility of combining with other products.

weak protection against UVA rays, destruction by heating, occlusive effect, insufficient cosmetic.

Additional components included.

In addition to filters, sunscreen formulas contain substances intended for skin care.

Under the influence of solar radiation, free radicals are formed in the skin – one of the main factors of aging. And to combat them, antioxidants (vitamin E, baicalin) are included in sunscreen formulas.

Provides a moisturizing and anti-aging effect, smoothes wrinkles and evens skin texture.

Indispensable in protective creams for oily skin: mattifies, controls sebum production, reduces inflammation.

How to use correctly.

As for the use of SPF creams, the main requirements are not to use products that have expired and to renew them on the skin in a timely manner. Details below.

Shelf life.

It is indicated on the package. On the packaging of products made in Europe, you can see the expiration date marking in accordance with European legislation – an image of a jar with an open lid and a number from 6 to 12, which indicates the number of months during which it is permissible to use the product after opening the package.

As a rule, sunscreen cosmetics have a short shelf life. And if you take the product with you to the beach – even less, because under the influence of the sun, the formula can transform and lose its protective properties. The universal rule for using SPF creams is not to use them for more than one season..

Application rules.

Here are the most common questions asked by professionals.

When to apply? It is recommended to apply a face cream with SPF to the skin 20-30 minutes before going outside – this time is enough for the filters of the product to be evenly distributed.

How much? The recommended rate is 2 ml of the product per 1 square centimeter of skin. Thus, the face will need the volume of a teaspoon, and the body may require up to 3 tablespoons of the product, depending on the area of ​​application. That’s quite a lot, and most people use half the product they need. As a result, the protection is unreliable. The exception is sunscreen sprays. Their texture is the most economical.

How often to update? During the day, the cream wears off and the protection weakens. To prevent this from happening, update the tool every 1.5-2 hours if you are outdoors.
