Tanned skin looks attractive, minor imperfections become less noticeable, and the whole face looks rested. But every year our sun becomes more and more aggressive, and people try not to sunbathe. What should sunbathers do to calmly enjoy the bright rays without harm to their health?
With the advent of sunlight, the body seems to wake up: vitamin D is actively synthesized, which is important for strengthening bones, heart muscle, stable functioning of the kidneys and liver, etc. The hormones of happiness are produced, the immune system is strengthened, the mood rises.
Ultraviolet radiation, within reasonable limits, benefits the body, and an overdose is harmful.
How the sun affects the skin
Our skin has a built-in sunburn protection mechanism. People are divided into several phototypes, each of which reacts differently to solar activity. Light-skinned people are most sensitive to ultraviolet light. They are more at risk of getting burned than those with dark or African skin.
Ultraviolet light consists of A (UVA) and B (UVB) rays. Scientists are constantly studying these types to create powerful protection for the skin.
Ultraviolet rays act not only on the surface of the skin, covering it with the desired tan, but also penetrate deep into the inner layers and provoke the appearance of wrinkles and disease.
Both types of rays are harmful to the skin, so the product should be double protected. According to cosmetologists, no sunscreen with SPF can protect us one hundred percent so far.
What are the funds with SPF
SPF is not a protection factor, as is commonly believed, but an indicator that determines the time spent in the sun that is optimal for the skin. For example, if your skin starts to redden under the sun without a cream after 5 minutes, then a product with SPF-10 will allow you to stay under active rays without harm for up to 50 minutes. The numbers are approximate, because it all depends on the type of skin.
Products with SPF do not allow the skin to burn and serve as protection for prolonged exposure to the sun, the maximum activity of which falls from 10 am to 16. The more intense the sun and the longer the stay on it, the higher the SPF should be. The most effective protection comes from SPF-15.
How to choose sun cream
Sunscreens should contain filters against the main ultraviolet rays of the A (UVA) and B (UVB) spectrum. The label may contain such information, but it is not always correct, you need to look at the composition. Most creams use physical UV filters that reflect rays like a screen; and chemicals that absorb UV radiation.
The main filters that should be in sunscreen: Titanium Dioxide, Zinc Oxide, Trolamine Salicylate, Octisalate (Octyl Salicylate), Oxybenzone, Dioxybenzone, Avobenzone, Meradimate (Menthyl Anthranilate) and others.
There is no universal protective cream. There are several factors to consider when buying:
- Age. Young skin resists radiation well and regenerates quickly. With age, you need to use a high protection factor.
- The level of ultraviolet radiation at the place of residence or location. For each region, information on the UV index can be checked on the Internet.
- Skin condition. Owners of sensitive skin, in the presence of many moles on the face, inflammation, as well as after cosmetic procedures, you need to use maximum protection.
- Lifestyle. For a work-to-home regime, creams with a mild to medium SPF level are suitable; if you are constantly outdoors, you must use products with a high level of protection.
How to apply SPF cream correctly
- Apply the product 20 minutes before sun exposure, otherwise you may burn yourself while the filters take effect.
- When making up, you need to use the main cream first, and then with SPF.
- Apply the cream after every bath. The water resistance of the products is in doubt, sunscreens will still lose their power.
- Do not leave the cream in direct sunlight to keep the filters effective.
- Do not apply the cream to the eye area. Filtered sunscreens are heavy on this area and can cause swelling. You can just put on quality sunglasses and a nice hat.
Sunbathing or not, everyone's business. The main thing is to take care of the skin in order to prevent various troubles.
