Should I wear sunscreen all year round?

Do I need to wear sunscreen all year round? Sunscreen is not only for sun protection, but also for ultraviolet protection. The damage of ultraviolet rays to our skin is obvious. There will be ultraviolet rays in summer and winter, so do you need to apply sunscreen all year round?

Should I wear sunscreen all year round? 1 sunscreen should be applied all year round, because ultraviolet rays are everywhere. Whether it is spring, summer, autumn and winter or rainy weather, ultraviolet rays have different degrees of radiation. Even in autumn and winter, due to the thin ozone layer, sometimes ultraviolet rays can reach the critical value of skin damage. Under normal circumstances, ultraviolet radiation is strongest in summer, so you can use sunscreen with a higher SPF, and sunscreen with a lower SPF in other seasons.

There are two kinds of ultraviolet rays harmful to the skin, long-wave ultraviolet UVA and medium-wave ultraviolet UVB. UVB will concentrate on the skin surface, causing skin redness and sunburn. UVA can penetrate buildings and even clothes and reach the dermis, which not only darkens the skin, but also accelerates the skin aging.

Clouds can only block some visible light and UVB on rainy days, but UVB can easily penetrate clouds and make our skin tan and age. Therefore, sunscreen should be applied all year round, even on cloudy or rainy days.

First of all, the amount of sunscreen

Many people wear sunscreen just to see their mood and squeeze a little on their faces. If the amount of sunscreen is not enough, then it can't play a good role in sunscreen. The most suitable dose for ordinary people to apply sunscreen every time is to squeeze out the size of a coin, and this dose is enough. Only when the dosage is enough can we have a better sunscreen effect.

Second, the time to apply sunscreen

Many people just put on a layer of sunscreen before going out, which can't play a good sunscreen effect. Because it takes a certain time for sunscreen to form a film on the face, we'd better apply sunscreen half an hour before going out, so that sunscreen can have enough time to form a film on the face and play a role in sun protection.

Third, the use time of sunscreen after opening.

Some people are still using last year's sunscreen this year, so they often have no way to protect themselves from the sun. The unopened sunscreen can be used for several years, but once it is opened, it should be used as soon as possible. It is best not to use sunscreen after changing seasons, which will lose the sunscreen effect. Therefore, exquisite girls should never feel bad about sunscreen, and use it as soon as possible so that there will be no waste.

Do you need sunscreen all year round? We need sunscreen and sunscreen in autumn and winter, otherwise we will get tanned and our skin will age faster.

The purpose of applying sunscreen is to prevent ultraviolet rays, which also exist in autumn and winter. Although a little weak, it has been affecting our skin. When our skin is exposed to too much ultraviolet radiation, it will be damaged, accelerate the precipitation of melanin, and the skin will become rough and dry, with fine lines and spots. In some places with higher altitude and snowy days, ultraviolet rays will be stronger and have a greater impact on our skin.

Some people think that the sun is not so strong in autumn and winter and mistakenly think that sunscreen is not needed, which is also the reason why many people unconsciously turn black. In fact, ultraviolet rays exist all year round, and sun protection should also be done well.

Pay attention to sun protection in autumn and winter:

First, choose different SPF sunscreens according to different seasons.

In autumn and winter, you can choose low-power sunscreen instead of high-power sunscreen. 15~20 SPF is enough to give our skin a chance to breathe. If you also apply sunscreen products with high SPF in autumn and winter, it will cause a great burden on your skin. Apply sunscreen about 20 minutes before going out, so it will be effective when going out, so that we won't get sunburned.

Second, apply sunscreen in time when going out.

Sunscreen is also time-sensitive. We apply sunscreen about 20 minutes before going out, but it only lasts for two or three hours because of sweating or oil. When we need to be exposed to the sun for a long time, we need to constantly apply a layer of sunscreen, so as to achieve the effect of sun protection.

Third, remove makeup when you get home.

Because sunscreen contains a lot of oil, it is not so refreshing to apply. After returning home, you need to use makeup remover to remove makeup, which will not affect your skin. If we can't clean them thoroughly, it will make our skin very greasy and lead to the problem of large pores.

Yes, sunscreen should be used all year round. Sunscreen is not only for sun protection, but also for ultraviolet protection. The damage of ultraviolet rays to our skin is obvious. No matter in summer or winter, there will be ultraviolet rays, so we need to wear sunscreen every day.

Can sunscreen be used for one year in Kaifeng?

Kaifeng is not available for one year.

The shelf life of unopened sunscreen is 1~3 years. If it has been opened, it is best to use it within one year, because improper contact with air and storage will greatly weaken the sunscreen effect and even cause skin allergies. Many people think that sun protection is only needed in summer, but it is not. Sunscreen should be done all year round. Whether it is sunny or rainy, ultraviolet rays will not disappear. In order to reduce the damage of ultraviolet rays to our skin, we must use sunscreen.

How long is the shelf life of general sunscreen?

The shelf life of sunscreen is usually three to five years. Although there are many brands of sunscreen, the shelf life of sunscreen produced by each brand is different, but the shelf life of unopened sunscreen in the market is generally three to five years, while the shelf life of unopened sunscreen is six months to one year.

The bottle of sunscreen is usually marked with the shelf life. Sunscreen is a sunscreen product that people use every day. Its shelf life is still relatively long. It can be kept unopened for at least three years and at most five years. However, after unsealing, the shelf life of sunscreen is greatly shortened, usually six months to one year.

Should eyes be protected from sun in summer?

Infrared rays, visible rays and ultraviolet rays in sunlight may cause harm to eyes. Under the same conditions, the younger the age, the more serious the retinal light damage. Although the damage caused by sunlight to the eyes is mostly light, it should not be underestimated that these injuries have cumulative effects, and even cataracts and retinal light damage may occur.

Moreover, the more transparent the crystal is, the more light it can transmit, which will cause retinal damage. This is also the reason why young people are more vulnerable to retinal light damage. Therefore, it is very necessary to wear a pair of sunglasses to protect your eyes from the sun besides wearing sunscreen when you go out.
