The principle of operation and structure of sunscreen for sunburn

Ultraviolet radiation is of 3 types: UVA, UVB, UVC. The last rays are very harmful to people, fortunately, they are absorbed by the atmosphere and do not reach the surface of the Earth. But the rays A and B affect the body, but in different concentrations.

Only 5% of UVB rays reach Earth, however, with prolonged exposure to the sun, this amount may be sufficient for the appearance of serious skin damage (up to tissue mutation and, as a result, oncology).

95% of UV rays are UVA rays. They surround us constantly, create a tan on the skin, with prolonged exposure lead to hypersensitivity, photo-aging of the skin (wrinkles, loss of elasticity).

Given the effect of the rays on the skin, dermatologists strongly recommend the use of sunscreen that protect the skin from burns. The presence of sunscreen does not prevent the skin from acquiring a dark shade. The tanning process will be less intensive than without the use of a cream, but safer.

As part of the means usually there are special substances that neutralize the action of the ultraviolet rays of the spectrum A and B - UV filters.

The following types of UV filters are distinguished:

1. Physical create a screen, not allowing rays to penetrate into the deep layers of the skin (titaniumdioxide, zincoxide, various siloxanes).

2. Chemicals penetrate the skin and convert solar energy into heat (benzoquinones, salicylic acid esters, etc.).

They indicate the level of protection of the cream from exposure to harmful sunlight: the higher the value, the higher the protection. You can find products on which the SPF is above 50 - this is nothing more than an advertising move.

Sunscreen selection options

Sunscreen Choice Parameters

UV protection level

This is the main parameter of the selection of sunscreens. The lighter and more sensitive the skin, the higher the level of protection should be. The same applies to mature skin, which is less tolerant of solar radiation than the young, so it is recommended to strengthen the protection in older children.

Choosing the level of SPF should be considered:

1. Duration of exposure to sunlight. People who are exposed to prolonged exposure to the sun require increased protection, so the SPF level should be at least 30;

2. UV index. The higher this parameter in your area, the more intensive protection is required. You can find out the value of this parameter in any smartphone when viewing the weather forecast.

Filter view

On the packaging manufacturer must indicate the type of sunlight that protects the cream. The most effective tool will be the one that protects simultaneously from several types of rays: UVA, UVB. Also, protection against UVA rays is sometimes labeled as IPD, PA + or PPD.

Additional substances

It is better to choose creams that contain vitamins B, C, A, F. They contribute to intensive moisturizing of the skin and have an antioxidant effect. Sometimes creams may contain alcohol to reduce the fat content of the texture.

It is known that alcohol dries the skin strongly, so after applying a feeling of tightness may appear, to prevent this from happening, choose a cream without alcohol or its minimum content.

In addition, creams may contain the following undesirable components that negatively affect skin cells:

1. Oxybenzone;

2. Retinylpalmitate;

3. Parabens.

Consistency

The cream should be quickly absorbed and not leave a greasy luster, so the tool should not be very thick and not very liquid.

Water resistance

With increased sweating or if swimming is planned it is better to choose a waterproof cream, so the effect of the agent will remain after exposure to water; it will not be necessary to reapply the cream after 15-20 minutes

Hypoallergenic

The presence of this parameter indicates that the cream has passed multiple clinical trials for an allergic reaction and after applying it does not appear burning, dryness, irritation and rash on the skin.

1. Dermatologists recommend having several sunscreens. Until the skin is tanned, you should buy a cream with an SPF of at least 30. When sunburn appears, it is better to switch to a cream with SPF up to 15. Those who want to avoid premature aging of the skin should get a cream with an SPF of at least 30.

2. If the sun rays are contraindicated for any reason (undergoing aggressive cosmetic procedures, hormone therapy, hyperpigmentation, etc.), then in the summer period constant intensive protection is necessary, therefore you should choose a cream with SPF30-50.

4. Children's skin requires more intensive protection than an adult, because it is especially prone to the negative effects of the sun. To prevent burns and preserve the health of the skin of the child should choose a cream with SPF 40-50.

5. As for filters, the more they will be present in sunscreen, the more skin will be protected. If a person wants to get a quick, intense tan, then you should choose a cream with protection against UVB rays. If the safety of sun exposure is in the first place, then it is better to purchase a cream with protection against UVB and UVA rays. The latter should also be purchased if the skin is tender and prone to irritation. However, it should be remembered that chemical filters become harmful after 2 hours after application, therefore, it is recommended to completely clean the skin and apply a new layer of cream.
