A moderate amount of sunlight is one of the recipes for external and internal beauty, as well as just a good mood. However, ultraviolet radiation, or rather its excess, can have a detrimental effect on health. Cream SPF - the most effective way to protect yourself from this influence!
SPF is a sunscreen factor that determines the duration of your stay in direct sunlight. In other words, SPF displays how many times your minimum dose of UV radiation increases with the use of a specific sunscreen.
Varieties of UV rays and their effect on the body
- UVA is a type that makes up 95% of the solar radiation reaching the earth (we are most exposed to it). UVA contributes to the tanning of the skin. Its excess can cause skin hardening, as well as a significant weakening of immunity.
- UVB is the radiation that makes up the remaining 5% of the sun's activity. The strongest is in the summer, from 10 to 16. Excessive exposure to the epidermis is caused by the appearance of burns, as well as abnormal mutations of skin cells.
The right choice of sunscreen is the only solution that will allow you to stay in direct sunlight longer without harm to your health!
How to choose sunscreen SPF correctly?
In order to choose the right cosmetic product from the sun, it is important to consider the following factors:
- Age of the user. For young skin (up to 35), it is better to use SPF creams with less sun protection factor!
- Lifestyle. The choice of cream is a cardinally different task for an office worker who only occasionally appears in the open air, and a young mother who walks all day with a child on the street.
- The state of the skin and its phototype (the classification in the table is given).
- The index of ultraviolet radiation in the region. The higher it is - the more sunscreen you need the cream!
Based on all these factors, determine the degree of protection of sunscreen - the main characteristic of the cosmetic products of this group!
Degrees of protection for sunscreens SPF
Conventionally, all products that block the harmful effects of the sun are divided into several groups:
- SPF with a factor of 2-4 - provide only basic protection. This means that 50 to 75% UV is blocked.
- SPF 4-10 - products that differ in their average protective performance (up to 85% UV).
- SPF 10-20 - cosmetic products, the task of which is to prevent 95% of the sun's rays (high protective level).
- SPF 20-30 - products that actively protect the skin from direct sun rays (97%!
- SPF 50 - Sanblocks blocking up to 99.5% of UV.

The composition of sunscreens SPF - the main indicator of efficiency!
Modern sunscreens combine physical and chemical filters:
- Physical - titanium dioxide or zinc oxide (create a screen reflecting the sun's rays).
- Chemical - Avobenzol, Benzophenol or others (adsorb ultraviolet rays).
In addition, in the composition of sunscreens SPF can include components such as glycerin, allantoin, Shea butter and others!
Have you found the right cream and are ready for the first use? At this stage, attention should be focused on the key mistakes in order to increase the effectiveness of sunscreens.
The main mistakes of use and recommendations for the sunscreen SPF:
- Apply this cosmetic product no later than 20 minutes before exposure to the sun. Otherwise, you will receive your dose of radiation even before the activation of the protective filters.
- The cream should be renewed after each bathing, wiping or simply felling in the sun for more than 2 hours.
- The anti-tanning agent used should not be exposed to direct sun rays - otherwise the effectiveness of the filters will be lost.
- When using sunscreens with different SPF indices, their protection can not be summed up, and may weaken!
- It is necessary to adhere to the application rates and the amount of the product distributed (at least 2 mg / cm2 of the body.
- The effectiveness of sunscreen SPF is noted even in the absence of a hot summer sun (in cloudy weather).
- Before distributing the cream, stop using perfumes and cosmetics!
- The application of the product should be carried out and on the closed areas of the body, because the sun's rays are able to penetrate and under the clothes!
Also it should be noted that in the Lambre collection with the function of sun protection, not only special products, but also ordinary day cream (series "Zen") or tonal base are doing good.
