What if you want sun protection but don t want to use sunscreen and parasols?

Yes, when the ultraviolet rays are sufficient, the sunscreen effect is not good, and the ultraviolet rays can pass through the parasol and hurt the human body.

Sunscreen is divided into physical sunscreen and chemical sunscreen, the application of sunscreen products is chemical sunscreen, and the use of sunscreen clothing and sunscreen umbrella is physical sunscreen.

Sometimes darkening is not due to sun exposure, it is the sun's ultraviolet rays that darken people, and ultraviolet rays maintain the same intensity throughout the day throughout the year, regardless of weather and season. Even on cloudy days, UV rays can penetrate the clouds and reach the ground, and applying sunscreen correctly and using sunscreen products can prevent sunburn, but it will still darken people, but it will delay the time of being tanned compared to not wiping it.

In summer, only wearing a parasol can protect you from the sun, but it is not comprehensive, and you still need to wear sunscreen.

How to use sunscreen correctly:

1.Use sunscreen all year round. Many people must only use sunscreen when it's hot, as they used to be, because our skin can be easily tanned by the sun.

In fact, not only in summer, but also in any season, even if it is cloudy, the power of ultraviolet rays can not be underestimated, although it is not visible now, but melanin slowly accumulates in our body, and it will have an impact on the skin over time.

2.Before using sunscreen, cleanse your skin before applying lotion. If you have dry skin, you can apply a layer of lotion after lotion, and then use sunscreen.

If you want to be exposed to sunlight for a long time, it is recommended that you use SPF30 PA+ or higher, and if you stay in the office for a long time in front of the computer, then only SPF15 PA+ products are enough.

3.Sunscreen must be applied evenly, and don't forget only the face, but forget the neck, arms and other parts.

4.Sunscreen should be applied about 20 minutes before going out, because sunscreen does not have the effect of sun protection, and it needs to give the skin time to absorb. And sunscreen doesn't last all day, so reapply it when you're sweating a lot or after a few hours of sunscreen.

5.Don't mix and match brands of sunscreen. In order to thoroughly protect themselves from the sun and protect their fair and delicate skin, many people use several brands of sunscreen to pursue better sunscreen effects.

This is not the right practice, as mixing multiple brands of sunscreen together will not only exclude each other, but may also cause allergies. In fact, many excellent sunscreens have good sun protection effects, and you don't need to use so many products.

6.Use a makeup remover. Don't think that you only need to use cleansing oil if you wear heavy makeup, but you still need to remove makeup when you use sunscreen and base cream to prevent sunscreen residue on your skin from clogging pores and causing various problems such as rough skin or acne.

Parasols can block out half of the light, but they don't provide complete sun protection. Because visible light and ultraviolet light can reach you indirectly through reflections elsewhere, 20% is reflected by water and 15-25% is reflected by sand. Need to be extra careful!

Make it a habit to use sunscreen all year round. Many people must be like Kochi before, and only use sunscreen in the summer when the weather is hot. Because our skin can be easily tanned by the sun.

In fact, not only in summer, but also in spring, autumn and winter, even if it is cloudy, the intensity of ultraviolet rays cannot be underestimated. Although it is not visible for a while, melanin slowly accumulates in our body, and it will affect the skin over time. Be sure to remove makeup every day after applying sunscreen.

Because the sunscreen itself is oil-soluble, and the long-lasting formula, waterproof formula, and facial cleanser are like "bathing in a separate clothes", so you can remove it most effectively and gently. If you don't remove your makeup thoroughly, it can easily clog pores and cause breakouts.

It can only be said that the effect is not very ideal. Double protection protects against the sun more than a parasol alone.

Oh, use sunscreen, I wear sunscreen and umbrella at the same time.

The ground also reflects the light.

Absolutely.

It's possible in Chengdu.

Many fashion magazines tell us that we should put on sunscreen half an hour before we go out, which is not wrong, but it is not entirely true. As for the reason for such guidance, I have hardly seen these ** to say clearly, and one of the most ridiculous explanations I have ever seen is that "the sunscreen ingredient will only take effect after half an hour of application", it seems that the author when the sunscreen ingredient is a time bomb, and it will not work until the time.

So why is there such a half-hour lead? In fact, the reason is very simple, using this half an hour, the epidermis layer can absorb the sunscreen ingredients in the sunscreen to a certain extent, and once it enters the epidermis layer instead of staying on the surface, it will not be washed off due to sweat and other reasons, which is helpful for maintaining a good sunscreen effect. Understanding this truth, we should actually be clear, not that sunscreen has to be applied half an hour before going out, and it is okay to hold your feet temporarily, but it will be easier to lose due to sweating, wiping and other reasons; At the same time, there is no need to apply sunscreen with purely physical properties in advance, because the epidermis layer will not absorb these physical sunscreen ingredients, no matter how much advance is used.

In fact, even if you apply sunscreen half an hour in advance, it is impossible to guarantee that there is no loss at all, so reapplying sunscreen after a certain period of time has become a necessary step - in fact, in my opinion, reapplying sunscreen is not only to make up for the loss of sunscreen ingredients before, but more importantly, it is important to achieve the amount of sunscreen products theoretically required by reapplying. As I mentioned before, all sunscreen indicators are measured based on the amount of 2mg cm2 applied, but most people tend to only apply the actual amount due to habits or consideration of texture and other issues, so the actual sunscreen effect may only be 20% to 30% of the theoretical effect. On the other hand, if you reapply sunscreen, you can divide the amount of one application into two parts, and gradually approach the amount of application that is theoretically needed through accumulation.

Therefore, even if there is no loss of sunscreen ingredients for any reason, it is necessary to reapply. For this step, traditional newspaper articles in newspapers and magazines will recommend that we apply it after 2-3 hours, is this really the best choice?

brian l.Diffey wrote in an article titled "When should sunscreen be reapplied?."This issue is discussed in detail.

He used a not too complicated linear regression model to calculate, the specific details will not be relayed here, interested readers can find the original literature l to see.

I'm just quoting one of his findings: sunscreen should be reapplied after 15-30 minutes of exposure to the sun, so that the UV protection can be optimised throughout the period.

Yes, because the sun protection of the sun umbrella is very limited, and there are many fakes, it is recommended that you buy a red sun umbrella, because the red is the best color to prevent ultraviolet rays, and the sun umbrella can not be used as an umbrella, and the sun umbrella that has been drenched in the rain is useless! If you have time, it's best to apply the barrier first and then apply sunscreen! In this way, it has an effect, and the post-sun repair can not be ignored!

Sunscreen is a hassle, I hope it can help you!

Parasols can block most of the UV rays, and people's ** is like this, if you are in the sun for more than 15 minutes in a row, it is easy to tan. If you are in the sun for half an hour in a row it is dangerous, it is better to have a double insurance - parasol plus sunscreen on 30+. If it doesn't take more than 15 minutes at a time, an umbrella is enough.

If you can afford it, it is recommended that you use sunscreen. It's not that there won't be ultraviolet rays where the sun can't shine, and the ones that are easy to darken ** will turn black after a long time, even indoors

Yes, the ground reflects 80% of ultraviolet light.

It's better to apply it, ultraviolet rays are eating away at our skin all the time.

10 minutes can hurt the skin, so insist on touching sunscreen products, and remember to buy three +++ 30 times more than as good Some sunscreen is applied 20 minutes before going out, and sunscreen should be applied last, and the body should also be touched, if the exposure time is long, the umbrella should be selected with UV protection, and the umbrella with an umbrella-shaped bow can cover the face.

Of course, it is good to wipe it, although the parasols on the market are said to have the function of preventing ultraviolet rays, but who can say for sure.

Sunscreen is the protection of the face, so the best strategy is to wear sunscreen, and also keep an umbrella open.

Absolutely. Be sure to do a good job of sun protection in summer.

It's hard to think about white when it's black.

In the summer, the ground radiation and reflection are very violent....

Do you still need to wear sunscreen with a parasol.

Yes, it can be used because umbrellas can also keep out the rain.

But parasols and umbrellas do differ in material.

It is better not to use a sun umbrella as an umbrella, otherwise the sun protection will lose faster.

The sun umbrella has a film that blocks ultraviolet rays, and it will be destroyed after rain" This sentence is completely true, because there is a sunscreen paint on the outside of the sun umbrella, which will gradually fade because it is often brushed by rain. Moreover, to protect the sunscreen effect of the sun umbrella, not only can it not be used as an umbrella, but also as little as possible, not to say don't use it, but only when necessary. Holding can also cause the sunscreen effect of the umbrella to fade prematurely.

The sun umbrella is still quite squeamish

Yes! The umbrella's UV protection film is on the inside and it's fine.

And it doesn't matter even if it's on the inside of the umbrella, the film is very strong, and you see if there's any transparency under the sun, and if there's a UV film, it's broken!!

The last time I looked at the Charm Front, I said that it was best to use an umbrella when it rained.

It is best to use the sun shade for rainwater, which is acidic and easy to corrode the coating.

The effect will be reduced.

Yes! UV rays. What's the matter with the rain? Look at your twenty points question, it's a bit wronged

Yes, some umbrellas have a sunscreen coating on the inside, even on the outside, and it is not something that can be worn off by a little wind and rain.

If the coating is still there, it's fine. It's okay to get drenched in the rain once or twice, don't worry.

It can protect against ultraviolet rays and protect your ** from ultraviolet rays.

The effect will be poor, so try not to get caught in the rain.

If you use it once or twice, it will not affect its sunscreen effect, but it is often used to keep out the rain, which will definitely cause the sunscreen film to fall off, thus affecting the sunscreen effect.

Professional should be fine.

It's a lot worse, I've tried it.
