Summer is beaches, walks, i.e. Vitamin D is produced under the influence of sunlight.
But now doctors advise not to go out without a special cream, because sunlight can cause skin aging and can cause skin cancer.
Ultraviolet rays are dangerous, which can be of 2 types: UVA and UVB. Because of the first, dark spots may appear on the skin, they are knotted with photoaging. And because of the second kind of rays, burns appear. They can cause cancer.
It is important not only to choose the right sunscreen, but also to use it. Let's talk about the main mistakes that most people make.
10. You bought the wrong cream
The best remedies are with physical sunscreens. They are safer than chemical ones. How to find out that this is the same cream? It should say “zinc” and “titanium dioxide” on its packaging.
Do not buy a cream that contains oxybenzone. Because of it, there may be health problems, because it negatively affects the hormonal background.
Methylisothiazolinone can cause allergies, and a painful rash can appear on the skin.
9. After applying the cream, you spend a lot of time in the sun
When choosing sunscreens, we often buy ones with an SPF of much more than 50. A person who uses this product is confident that he is reliably protected from ultraviolet rays.
But experts warn that, even with a cream, you can not be in direct sunlight for a long time.
In European countries, Japan generally does not produce products whose protection level is higher than SPF 50. So, a cream with SPF 50 does not pass 98% of the rays, and if it is labeled 100 - 99%. This is a common marketing move to increase sales.
8. You treat the skin with sunscreen not at home, but on the beach
If you are going to sunbathe, apply the cream in advance. Experts say that it is absorbed into the skin in 10-15 minutes, and if it is with chemical protection filters, it takes another quarter hour.
In those half an hour before the cream started to “work”, the sun's rays will have their negative effect on the skin.
7. Do not update the sunscreen
Like any cosmetics, sunscreen can be washed off. Usually we go to the beach to sunbathe and swim.
After you come out of the water, you need to re-lubricate the skin with cream. Even if it is written on it that it is “waterproof”, this does not guarantee that the product will stay on the skin.
Experts advise updating the cream layer every 2-3 hours, and if you constantly bathe - every hour.
6. Take cream only to the beach
In the summer you have to spend a lot of time on the street. Do not forget to use sunscreen cosmetics, even if you went on business by car or have a good time with friends in a cafe.
UV rays penetrate even through glass. The ultraviolet spectrum is divided into ultraviolet-A, ultraviolet-B and ultraviolet-C. Ultraviolet A can pass through the glass.
The sun that hits you through the window is also dangerous. You won’t get a tan, but overheating or burning a skin is not excluded.
5. You do not store sunscreen makeup properly
So that the cream does not lose its protective properties, it must be stored in a dry place, where the sun does not fall. Do not leave it in a hot, stuffy car, where the air temperature reaches 40 ° C. Otherwise, the cream will exfoliate into water and fat, it can not be used.
Better to find a place for him in his purse. Remember that with improper storage the shelf life of the cream is drastically reduced.
4. Protective cream should be applied only on sunny days
Do not neglect sunscreens, even if you are hiding in the shade. On cloudy days, our skin needs protection. Scientists from the American Academy of Dermatology were able to prove that 80% of UV rays penetrate through the clouds and can affect the skin.
Even if you hide under a special umbrella from the sun, more than 30% of ultraviolet radiation affects our body. For cloudy days it is better to buy a special cream, which has a lower level of SPF.
3. You do not buy cream, because use regular cosmetics
Now they began to produce special cosmetics for the face, the manufacturers of which promise that it will protect from the sun. But experience shows that this is not enough. And some types of cosmetics generally can not protect the skin from UV rays, because it is applied in a thin layer, and even then not everywhere.
You need to be able to combine cosmetics and sun protection. If your chosen cream has physical filters, then you can apply everything in the way that suits you best.
When using chemical filters, the cream is applied only to a clean body. After it is well absorbed, i.e. after 20 minutes, you can apply leaving creams or decorative cosmetics.
2. Apply cream to the whole body
Walking along the beach or being under the hot sun, we often do not apply sun protection under clothes. It seems pointless to use it under clothes, but a T-shirt or other things still let in about 70% of UVA rays and about 20% of UVB rays.
Therefore, being in the open sun, you still risk getting burns. Going for a walk, be sure to apply cream on the whole body, even under clothes. It is especially important to protect such vulnerable areas as the nose, chest, ears and forehead.
1. Do not apply sun cream on lips
Lips also need protection from the sun, but do not lubricate them with creams with UV filters. They have too heavy and dense texture, so they can not stay on the lips.
Specialists advise choosing special tools, i.e. lip balms or oils that have UV filters. You can buy hygienic lipstick.
The advantage of these products is that they not only protect the lips from the sun, but also decorate them, because come with various "effects", for example, with sparkling particles.
